Iranian Foreign Minister Javad Zarif dismissed the U.S. claim. “US wants to resort to int'l conventions to make allegations against Iran when it's made a policy of violating them itself.

German Chancellor Angela Merkel rejected the demand.

April 8 – The United States announced the designation of the Islamic Revolutionary Guard Corps (IRGC) as a Foreign Terrorist Organization (FTO), effective April 15. The IRGC is Iran’s most powerful military and security organization as well as a key economic player. “This unprecedented step, led by the Department of State, recognizes the reality that Iran is not only a State Sponsor of Terrorism, but that the IRGC actively participates in, finances, and promotes terrorism as a tool of statecraft,” said President Donald Trump. He noted that it was the “first time that the United States has ever named part of another government as a FTO.” In response, Iran’s Supreme National Security Council designated U.S. Central Command forces as terrorists and the U.S. as a “sponsor of terrorism.”

He noted that oil sales accounted for up to 40 percent of Iran’s revenue. The Trump administration's stated goal was to bring Iranian exports down to zero.

Pakistani Prime Minister Imran Khan visited Tehran. Khan and Iranian President Rouhani announced their countries’ intent to establish a joint border security force in Baluchistan.

May 3 – The United States sanctioned imports of enriched uranium from Iran. JCPOA signatory countries—notably Russia—had imported Iran’s enriched uranium to prevent Tehran’s supply from exceeding the JCPOA’s cap. The U.S. sanctions made it impossible for Iran to remain within JCPOA limits without halting its enrichment. The United States extended sanctions waivers that allowed foreign firms to work on reconfiguring Iranian reactors for civilian use and that allowed countries to provide enriched uranium fuel for civilian reactors in Bushehr and Tehran.

May 8 – President Hassan Rouhani announced that Iran was suspending some of its JCPOA commitments. It would no longer send enriched uranium abroad (doing so had already been made difficult by U.S. sanctions), which would cause Iran’s stockpiles of enriched uranium to exceed the JCPOA limit by early July. Rouhani said that Iran would begin enriching its uranium to higher levels and would restart work on the Arak heavy water plant if other JCPOA signatories did not protect Iran’s oil and banking sectors from U.S. sanctions within 60 days. “We have given deadlines to JCPOA member states several times,” he said. "In simpler language, we felt that there was a need for surgery and the one-year-old painkillers were not enough; today's action is a surgical procedure to save the JCPOA, not to end it.”

May 12 – Four ships off the coast of the United Arab Emirates (UAE) were sabotaged, including two Saudi Arabian oil tankers. One was due to take a delivery of Saudi oil to the United States. “Fortunately, the attack didn't lead to any casualties or oil spill; however, it caused significant damage to the structures of the two vessels,” said Khalid al-Falih, the kingdom’s energy minister. The UAE did not speculate on who might have been responsible, but the alleged attack came as the United States warned that “Iran or its proxies” could target maritime traffic in and around the Persian Gulf. Iran denied any involvement and accused the Trump administration officials of trying to frame it.

Yemen’s Houthi rebels also carried out a drone attack on two Saudi pipeline pump stations, damaging one. Saudi Arabia’s defense minister Khalid bin Salman blamed Iran, “The attack by the Iranian-backed Houthi militias against the two Aramco pumping stations proves that these militias are merely a tool that Iran's regime uses to implement its expansionist agenda in the region, and not to protect the people of Yemen as the Houthis falsely claim.”

May 12-18 – Foreign Minister Zarif visited India, Japan, and China to seek economic relief after the United States halted sanctions waivers on Iranian oil imports for those countries. He received only tepid support. “The Chinese side is willing to, together with the Iranian side, eliminate the interference of complex factors to fully implement the JCPOA,” the Chinese Foreign Ministry said in a statement. On May 23, India announced that it had ceased oil imports from Iran.

May 22 – Heshmatollah Falahatpisheh, the chairman of Parliament’s national security and foreign policy committee said that Iran will “under no circumstances” enter a war with the United States. “No group can announce that it has entered a proxy war from Iran’s side,” he said, according to ILNA via the Associated Press

May 23 - Oman’s Foreign Ministry said it was working to ease tensions between Iran and the United States. It tweeted remarks made by Foreign Minister Alawi in an interview with Al-Sharq Al-Wasat. Alawi warned that war “could harm the entire world if it breaks out.” 

May 25 – Foreign Minister Zarif visited Pakistan for the tenth time in his six-year tenure. Relations between Iran and Pakistan, previously marked by tension and mistrust, appeared to be improving. “Pakistan understands our position [vis-à-vis the United States in the Persian Gulf],” Zarif said after his meetings in Islamabad.

May 26 – Iraqi Foreign Minister Mohammed al Hakim said his country would like to help deescalate tensions between Iran and the United States. “We are trying to help and to be mediators,” he said at a joint press conference with Iranian Foreign Minister Zarif. Hakim added that Baghdad does not approve of unilateral steps taken by Washington. Zarif called for a non-aggression pact between Iran and the Arab Gulf states. 

May 27 – President Trump offered to negotiate a new nuclear deal with Iran and identified nuclear weapons as his priority. “It [Iran] has a chance to be a great country with the same leadership,” Trump said. “We aren’t looking for regime change - I just want to make that clear. We are looking for no nuclear weapons.”

June 10 – Foreign Minister Zarif warned that the United States “cannot expect to stay safe” after waging what he called an “economic war” against Iran. “The only solution for reducing tensions in this region is stopping that economic war,” he said during a visit by his German counterpart. “Whoever starts a war with us will not be the one who finishes it,” he added. The combative language was uncharacteristic of the top diplomat. 

June 13 – Two more tankers – one owned by Japan and one owned by Norway – were attacked in the Gulf of Oman. The second ship, the Front Altair, may have been targeted by a torpedo, according to CPC Corp, which chartered the ship. The Front Altair’s crew of 23 were reportedly rescued by the Hyundai Dubai vessel and were transferred to an Iranian navy vessel bound for the Iranian port of Bandar Abbas. Iranian state media claimed that all 44 crew members from both ships were rescued by Iranian teams. The U.S. Navy offered aid in dealing with the two damaged tankers.

Secretary of State Mike Pompeo blamed the attacks – and other incidents in Iraq and Afghanistan – on Iran. He said the U.S. judgement was based on intelligence, “weapons used, the level of expertise needed to execute the operation, recent similar Iranian attacks on shipping, and the fact that no proxy group operating in the area has the resources and proficiency to act with such a high degree of sophistication.” U.S. Central Command (CENTCOM) released a video allegedly showing Iranian sailors removing a mine from the Kokura Courageous’ hull. Iranian Foreign Minister Mohammad Javad Zarif denied Iran’s responsibility and said the timing was beyond “suspicious.”

Japanese Prime Minister Shinzo Abe was in Tehran at the time to deliver a message from President Trump to Supreme Leader Khamenei. “I do not see Trump as worthy of any message exchange, and I do not have any reply for him, now or in future,” Khamenei told Abe.

June 15 – President Rouhani reiterated his warning that Iran will  “terminate the implementation of some of its obligations” under the JCPOA unless other signatories show “positive signals.” Iran “cannot stick to this agreement unilaterally,” he told Chinese, Russian and other Asian leaders at Conference on Interaction and Confidence Building Measures in Asia (CICA).

June 17 – An AEOI spokesman announced that Iran would surpass the JCPOA’s low-enriched uranium stockpile limit on June 27. Behrouz Kamalvandi accused European countries of “killing time” rather than moving to ensure Iran would derive significant economic benefits from the nuclear deal. “If this condition continues, there will be no deal” anymore, he warned. President Trump said in an interview that he would “certainly” go to war with Iran “over nuclear weapons.”

U.S. Central Command (CENTCOM) released  high-resolution photos allegedly showing an IRGC boat removing an unexploded mine from the Kokuka Courageous. Additional photos showed a magnetic device that the mine was attached to and damage to the tanker’s hull. 

Acting Defense Secretary Shanahan authorized  the deployment of 1,000 additional troops to the Middle East. “The recent Iranian attacks validate the reliable, credible intelligence we have received on hostile behavior by Iranian forces and their proxy groups that threaten United States personnel and interests across the region,” he said. Shanahan reiterated that the United States was not seeking a conflict with Iran and that the action was solely “defensive.”

June 19 – The U.S. Navy presented  limpet mine fragments that allegedly linked Iran to the attack on the Kokuka Courageous. “The limpet mine that was used in the attack is distinguishable and also strikingly bearing a resemblance to Iranian mines that have already been publicly displayed in Iranian military parades,” said Sean Kido, commanding officer of an explosive ordnance dive and salvage task group in the U.S. Naval Forces Central Command (NAVCENT).

June 20 – Iran shot down a U.S. military surveillance drone. The Islamic Revolutionary Guard Corps (IRGC) claimed it downed an RQ-4 Global Hawk after it violated Iranian airspace. The United States confirmed that the drone was shot down but claimed that it was flying over international waters.

June 21 – President Trump ordered  a retaliatory strike on Iranian radar and missile batteries, but called off the attack at the last minute. "Planes were in the air and ships were in position, but no missiles had been fired when word came to stand down," according to a senior administrative official. Trump confirmed that he had aborted the operation. He said that the strike, which was estimated to kill 150 Iranians, would have been disproportionate to the downing of the unmanned drone.

Tehran claimed  that it had refrained from shooting down a U.S. military aircraft with 35 people on board. “With the U.S. drone in the region there was also an American P-8 plane with 35 people on board. This plane also entered our airspace and we could have shot it down, but we did not,” said Amirali Hajizadeh, head of the IRGC aerospace division.

June 21 – Russian Deputy Foreign Minister Sergei Ryabkov announced that Russia would help Iran export oil if the European Union’s INSTEX trade mechanism failed to launch. INSTEX had failed to gain traction since its announcement in Jan. 2019 because European businesses feared using it would cost them access to the U.S. market.

June 22 – The Department of Homeland Security said that it had observed a rising number of malicious cyber activities directed at U.S. government agencies by Iranian state actors and proxies. “What might start as an account compromise, where you think you might just lose data, can quickly become a situation where you’ve lost your whole network,” Cybersecurity and Infrastructure Security Agency Director Christopher C. Krebs said  in a statement. 

The Associated Press reported  that U.S. Cyber Command launched a strike against Iranian military computer systems on June 21. The cyber attack disabled IRGC computer systems that controlled rocket and missile launchers, according to three officials who spoke on condition of anonymity.

Iran executed Jalal Hajizavar, a former defense ministry employee, on charges of spying for the Central Intelligence Agency. Iranian state media reported  that Hajizavar had “openly confessed” to the espionage charges after spying equipment and documents were found in his home. On June 18, the United States, however, denied  Iran’s claims that it had dismantled a spying network. 

June 24 – The United States imposed sanctions on Supreme Leader Khamenei and members of his office. Foreign Ministry Spokesman Abbas Mousavi said that the new sanctions meant “closing the door of diplomacy” between the United States and Iran. Presidents Trump and Rouhani traded insults; Rouhani said that the White House was “afflicted by mental retardation,” and Trump threatened “obliteration” in response to future Iranian attacks on “anything American.”

July 1 – Iran breached the terms of the 2015 nuclear deal by exceeding limits on its stockpile of low-enriched uranium. Tehran is only allowed to store 300 kilograms of low-enriched uranium under the deal, negotiated by six major world powers. It is supposed to sell or exchange any surplus. "We told the Europeans that if more practical, mature and complete measures were taken, Iran's reduction (to its) commitments could be reversed. Otherwise, we will continue," said  Foreign Ministry Spokesman Abbas Mousavi.

July 2  – The foreign ministers of Germany, France, and Britain said they were “extremely concerned” by Iran’s decision to breach the 2015 nuclear deal. “We regret this decision by Iran, which calls into question an essential instrument of nuclear non-proliferation,” they said in a joint statement  with the EU High Representative to Iran. 

July 3 – President Hassan Rouhani threatened  to increase Iran’s enriched uranium levels to “any amount we want” if European countries do not find a way to sidestep U.S. sanctions by July 7. “Our level of enrichment will no longer be 3.67. We will put this commitment aside by whatever amount we feel like, by whatever amount is our necessity, our need. We will take this above 3.67,” said Rouhani on July 3. 

July 8 – Iran began  enriching uranium past the 3.67 percent mark specified by the 2015 nuclear agreement.  The Atomic Energy Organization of Iran announced that it was enriching uranium at 4.5 percent. The IAEA confirmed  the breach after an inspection. Foreign Ministry spokesman Abbas Mousavi warned that Iran’s next step will be “harder, more steadfast and somehow stunning” if European countries do not find a way to bypass U.S. sanctions.  

July 14 – President Hassan Rouhani said  Iran was ready to hold discussions with the United States if the Trump administration agreed to end crippling sanctions and return to the 2015 nuclear deal. “We have always believed in talks ... if they lift sanctions, end the imposed economic pressure and return to the deal, we are ready to hold talks with America today, right now and anywhere,” said Rouhani on state television.  

Secretary of State Mike Pompeo seemed to reject Rouhani’s offer. “President Trump will obviously make the final decision. But this is a path that the previous administration had gone down and it led to the (Iran nuclear deal) which this administration, President Trump and I both believe was a disaster,” he said.  

July 15 – Iranian Foreign Minister Mohammad Javad Zarif said  the door was “wide open” to negotiations if the Trump administration lifted economic sanctions against Tehran. He claimed Iran favored diplomacy and did not want to go to war with the United States. "I do not believe that President Trump wants war. But I believe that people are around him who wouldn't mind," Zarif said. "But I don't think they'll succeed because at the end of the day, I think prudence will prevail. People know that Iran is a big, proud country. And we will not take a military attack lightly." 

The United Nations expressed  concern that the United States was restricting Iranian Foreign Minister Mohammad Javad Zarif to only three locations during his visit to New York City. Government officials said that Zarif could only travel between the United Nations, the Iranian U.N. mission, the Iranian U.N. ambassador’s residence. Zarif’s restrictions were “fully consistent” with 1947 U.N. “headquarters agreement” according to U.S. officials.  

July 16 – President Trump reassured  that the United States was not seeking to topple the Iranian regime. “We’ll be good to them, we’ll work with them. We’ll help them in any way we can, but they can’t have a nuclear weapon. We’re not looking, by the way, for regime change,” Trump told reporters. He added that a lot of progress had been made in negotiations with Tehran.  

July 18  President Trump said  that the U.S. downed an Iranian drone when it came within 1,000 yards of the USS Boxer in the Persian Gulf. The drone was brought down using electronic jamming after ignoring “multiple calls to stand down." "This is the latest of many provocative and hostile actions by Iran against vessels operating in international waters. The United States reserves the right to defend our personnel, our facilities and interest and calls upon all nations to condemn Iran's attempts to disrupt freedom of navigation and global commerce,” Trump stated.  

July 19 – Tehran denied  that the U.S. had downed one of its drones and said it would release images disproving the American claim. “All Iranian drones that are in the Persian Gulf and the Strait of Hormuz, including the one which the U.S. mentioned, after carrying out scheduled identification and control missions, have returned to their bases,”said Iran’s top military spokesman Brig. Gen. Abolfazl Shekari. Deputy Foreign Minister Abbas Araghchi also refuted the U.S. statement in a tweet.  

The Pentagon announced  a “multinational maritime effort” called Operation Sentinel “to increase surveillance of and security in key waterways in the Middle East to ensure freedom of navigation in light of recent events in the Arabian Gulf region.” The campaign would provide coordinated escorts for the flagged vessels of participating nations. U.S. Central Command also approved  the deployment of 500 troops to Saudi Arabia as “an additional deterrent” to Iran. Riyadh accepted the basing agreement that placed U.S. combat troops in Saudi Arabia for the first time in over a decade.  

July 22 – Iran claimed  it uncovered a CIA spy ring and detained 17 citizens on charges of espionage. Iranian intelligence officials said the U.S. spies worked in sensitive military and nuclear facilities around the country. "Individuals who consciously and deliberately betrayed the country and refused to compensate for the losses have been handed over to the judiciary system. Others, who honestly cooperated with the security system and their remorsefulness have been proved, have been managed with intelligence direction against Americans," said  Iran’s Intelligence Ministry.  

Secretary of State Mike Pompeo urged caution in trusting the Iranian reports. “The Iranian regime has a long history of lying ... I would take with a significant grain of salt any Iranian assertion about actions that they’ve taken,” he said.  President Trump later categorically denied Tehran’s claims in a tweet.  

July 25 – U.S. Secretary of State Mike Pompeo said  he would go to Iran for talks on regional security if invited. He added that he would welcome the opportunity “to speak directly to the Iranian people.” Three days later, Pompeo said Tehran had not accepted his offer.

July 31 – The U.S. Treasury sanctioned  Iranian Foreign Minister Zarif for acting on behalf of Supreme Leader Khamenei. “Iran’s Foreign Ministry is not merely the diplomatic arm of the Islamic Republic but also a means of advancing many of the Supreme Leader’s destabilizing policies,” said Secretary of State Mike Pompeo. “Foreign Minister Zarif is a key enabler of Ayatollah Khamenei’s policies throughout the region and around the world. The designation of Javad Zarif today reflects this reality.”  

Iranian President Hassan Rouhani called  the designation “childish.” In a defiant tweet, Zarif said, “Thank you for considering me such a huge threat to your agenda.”

The U.S. State Department renewed  five sanctions waivers permitting foreign firms to work on Iran’s civil nuclear program without penalties. The waivers, which were renewed for an additional 90 days, specifically permitted European, Russian, and Chinese companies to continue civil nuclear projects at Iranian nuclear facilities.   

Aug. 5 – Iranian Foreign Minister Mohammad Javad Zarif said  that he was given an invitation to the White House by Senator Rand Paul. “During my trip to New York, I was told I would be sanctioned within two weeks unless I accept their invitation, which I rejected,” he claimed. Zarif added that the U.S. sanctions against him represented a “failure” in diplomacy. 

Aug. 6 – Iranian President Hassan Rouhani said  the United States must lift all sanctions before negotiations could begin. “Peace with Iran is the mother of all peace, war with Iran is the mother of all wars,” he warned.  

Aug. 11 – Supreme Leader Ayatollah Ali Khamenei urged  haj pilgrims to protest a U.S. plan to end the Palestinian-Israeli conflict. “The trick called ‘Deal of the Century’, which is being pushed by an oppressive America and its traitorous companions, is a crime against human society, and not just the Palestinian people,” he told Iranian pilgrims at a rally.

Aug. 15 – Gibraltar released  the Grace 1, an Iranian oil tanker impounded by Britain since July 4, despite a U.S. bid to prolong the detention. The United States applied to seize the Iranian tanker, but a Gibraltar court denied the request. Gibraltar Chief Minister Fabian Picardo said the United States could file a new appeal, but ordered the tanker’s immediate release after the Iranian government provided documentation that the ship would not deliver oil to Syria.  

Aug. 18 – The Adrian Darya 1, renamed from the Grace 1 and re-flagged from Panama Iran, left  Gibraltar for Kalamata, Greece after being detained by Britain for over a month. On August 16, the United States issued a warrant to seize the tanker and its 2.1 million barrels of crude oil. But the Gibraltar government said it could not comply with the request because U.S. sanctions against Iran did not apply in the European Union.

Aug. 26  French President Emmanuel Macron told  reporters after the G7 summit that he hoped to arrange a meeting between President Trump and Iranian President Hassan Rouhani “in the coming weeks.” Trump said there was a “really good chance” for a potential meeting with Rouhani.  

Rouhani initially signaled his openness to negotiations. “If I knew that going to a meeting and visiting a person would help my country’s development and resolve the problems of the people, I would not miss it,” he said  in a televised speech.

Aug. 27  In a televised speech, Rouhani said  that Iran is ready to hold talks. “But first the U.S. should act by lifting all illegal, unjust and unfair sanctions imposed on Iran.” He called on Washington to demonstrate good faith ahead of potential negotiations. “Washington has the key for positive change ... So take the first step ... Without this step, this lock will not be unlocked.” He also warned that Iran could continue to curb its compliance with the JCPOA if its economic interests are not guaranteed. Rouhani, like many other Iranian officials, reiterated that Iran would never seek nuclear weapons because Supreme Leader Ayatollah Ali Khamenei issued a fatwa (religious decree) in the 2003 banning them.

Sept. 4 – Trump told reporters that “anything is possible” when asked about a meeting with Rouhani on the sidelines of the U.N. General Assembly opening. “We’re going to see what happens. They want to talk. They want to make a deal,” he said. “I very much appreciate President Macron’s involvement but we’re not dealing through President Macron, we’re dealing with people directly.”

U.S. Special Representative for Iran Brian Hook announced a reward of up to $15 million for any person who provides information that could disrupt the financial operations of Iran’s Revolutionary Guard Corps (IRGC) and Qods Force. “Today’s announcement is historic. It’s the first time that the United States has offered a reward for information that disrupts a government entity’s financial operations,” said Hook. He also outlined Treasury designations of more than 25 entities and individuals and 11 vessels involved in what he described as an IRGC “oil-for-terror network” that illicitly shipped oil to Syria and elsewhere. In a tweet, Zarif called the reward offer “outright blackmail.”

Rouhani announced  Iran’s third step in rolling back its commitments to the JCPOA in a speech late at night on state television. “The Atomic Energy Organization [of Iran] is ordered to immediately start whatever is needed in the field of research and development, and abandon all the commitments that were in place regarding research and development,” he said. 

Sept. 8 – Two diplomatic sources told Reuters  that the IAEA found uranium traces at a site that Israeli Prime Minister Netanyahu alleged was a “secret atomic warehouse.” The uranium was not highly enriched but called Tehran’s transparency into question. U.S. National Security Advisor John Bolton demanded a report as soon as possible.

Sept. 9 – Prime Minister Netanyahu alleged  that Iran conducted experiments relating to nuclear weapons development at a site near the city of Abadeh. “When Iran realized that we uncovered the site, here’s what they did,” he said in televised remarks, showing a photograph of the site from a month later. “They destroyed the site. They just wiped it out.”

On Twitter, Foreign Minister Zarif accused Netanyahu of lying and posted  a picture of a newspaper story discussing Israel’s undeclared nuclear arsenal in Dimona. 

Sept. 14 – The United States accused Iran of facilitating drone attacks on two major Saudi oil facilities. "Amid all the calls for de-escalation, Iran has now launched an unprecedented attack on the world's energy supply. There is no evidence the attacks came from Yemen," said Secretary of State Mike Pompeo. He added that Tehran had “pretended to engage in diplomacy” with the United States.  

Iran denied any responsibility for the attacks. On September 15, Foreign Minister Mohammad Javad Zarif said blaming Iran would not end the regional conflict. "Having failed at max pressure, Sec Pompeo is turning to max deceit,” Zarif tweeted. 

Sept. 15 – President Trump walked back  previous offers to negotiate with Tehran without preconditions. He blamed the “Fake News” for the reports, which he called “incorrect." 

Sept. 17 –  Iran’s supreme leader ruled out  the possibility of bilateral talks with Washington. His remarks came one day after President Trump blamed Iran for an attack on Saudi oil facilities that cut production in half. Tehran denied involvement. In remarks to seminary students, Ayatollah Ali Khamenei seemed to rule out a potential meeting between President Rouhani and President Trump on the sidelines of the U.N. General Assembly later in September. “The policy of maximum pressure on the Iranian nation is of little importance, and all the officials in the Islamic Republic unanimously believe that there will be no negotiations at any level with the United States,” said Khamenei.  

Sept. 18 –  Secretary of State Mike Pompeo called  the attacks on Saudi Arabian oil facilities an “act of war.” He denied claims that the attacks originated in Yemen. "As for how we know, the equipment used is unknown to be in the Houthi arsenal. These line attack cruise missiles we have never seen there and we think we’ve seen most everything,” Pompeo said. President Trump said  the United States would “substantially increase sanctions” against Tehran within the next 48 hours.

Sept. 19 — Iranian Foreign Minister warned  that Tehran could respond to a U.S. or Saudi military strike with “all-out war.” He questioned Saudi resolve and told CNN that the kingdom was prepared to fight "to the last American soldier." Zarif said Tehran hoped to avoid conflict but added, “We won't blink to defend our territory.”

Sept. 20 —President Trump announced sanctions on Iran’s central bank. “We’ve never done it at this level,” he told reporters in the Oval Office. “It’s too bad what’s happening with Iran. It’s going to hell.” Trump added, “They are broke and they could solve the problem very easily. All they have to do is stop with the terror.” Trump had directed the Treasury to increase sanctions on Iran following the September 14 drone and cruise missile strike on Saudi oil facilities, which Washington blamed on Tehran. Iran denied involvement. “Attacking other nations and disrupting the global economy has a price. The regime in Tehran must be held accountable through diplomatic isolation and economic pressure,” said Secretary of State Mike Pompeo. 

The United States also sanctioned the National Development Fund of Iran and Etemad Tejarate Pars Co., which allegedly conceals financial transfers for military purchases. Treasury Secretary Steven Mnuchin said the measures would cut off Tehran’s last remaining source of funds.

Sept. 25 – The IAEA found that Iran had breached the JCPOA again by using advanced centrifuges to enrich uranium. The U.N. watchdog “verified that all of the (centrifuge) cascades already installed in R&D lines 2 and 3 ... were accumulating, or had been prepared to accumulate, enriched uranium,” according to a new report. The JCPOA only allowed Iran to use some 5,000 of its first-generation IR-1 centrifuges to enrich uranium. Advanced centrifuges were supposed to only be used in small numbers for research purposes. 

The United States announced sanctions on five Chinese companies and six Chinese nationals accused of importing oil from Iran. The United States designated the China Concord Petroleum Co. Ltd., and two units of a major Chinese shipping company, Cosco Shipping Tanker (Dalian) Co. Ltd. and Cosco Shipping Tanker (Dalian) Seaman and Ship Management Co. Ltd. Washington also sanctioned the companies’ top executives. “We are telling China, and all nations: know that we will sanction every violation,” said U.S. Secretary of State Mike Pompeo during a speech at the United Against Nuclear Iran Summit. 

Oct. 5 - Iran released Jolie King, a British-Australian dual citizen, and her Australian boyfriend, Mark Firkin after three months of detention. In June 2019, the two travel bloggers were detained during a cross-continent trek from Perth, Australia to London.  The couple was arrested for flying a drone near Tehran without a permit, according to a prominent Iranian journalist. Iran dropped all charges against the travel bloggers following “very sensitive negotiations” with the Australian government. 

Nov. 4 – Iran began operating 30 new IR-6 centrifuges, doubling its number of the advanced machines. The chief of the Atomic Energy Organization of Iran, Ali Akbar Salehi, said Iran was operating a total of 60 of the centrifuges, which are some 10 times more efficient than the IR-1s allowed under the JCPOA. The announcement coincided with the 40th anniversary of the takeover of the U.S. embassy in Tehran by students.  

Salehi said that Iran went from producing about 450 grams (1 pound) of low-enriched uranium a day to 5 kilograms (11 pounds). He said Iran’s stockpile had grown beyond 500 kilograms (1,102 pounds). The JCPOA had limited Iran’s stockpile to 300 kilograms (661 pounds). 

Nov. 4 – The United States marked 40 years since the seizure of its embassy in Tehran by announcing new sanctions on Iran. The Treasury Department blacklisted nine members of the supreme leader’s inner circle. “The designation seeks to block funds from flowing to a shadow network of Khamenei’s military and foreign affairs advisors who have for decades oppressed the Iranian people, supported terrorism, and advanced destabilizing policies around the world,” Secretary of State Mike Pompeo said. 

Nov. 5 – President Hassan Rouhani announced that Iran would start injecting gas into 1,044 centrifuges at Fordo. The heavily fortified facility, built inside a mountain, was intended to be a research facility under the JCPOA, not an active site. The IR-1 centrifuges at Fordo had been spinning but were not enriching uranium. Ali Akbar Salehi, the head of the Atomic Energy Organization of Iran, said Iran would begin enriching uranium to five percent at Fordo. Iran injected uranium gas into the centrifuges at Fordo on November 7. Secretary of State Pompeo accused Tehran of extorting the international community into accepting its nuclear program and behavior in the region 

Nov. 6 – Iran reportedly held IAEA inspector and confiscated her travel documents while she was at the Natanz nuclear facility. The 2015 nuclear deal allowed for periodic IAEA inspections to ensure Iran was adhering to regulations. The IAEA’s Board of Governors convened an emergency meeting on November 7 to discuss the matters. 

Nov. 11 – In its quarterly report, the U.N. nuclear watchdog said that Iran had violated the 2015 nuclear deal by increasing its stockpile of enriched uranium. The IAEA also reported that its inspectors had found traces of uranium “at a location in Iran not declared to the agency.”  

France, Germany, Britain, and the European Union issued a joint statement saying they were “extremely concerned” by Iran’s latest moves. “Iran’s action is inconsistent with the JCPOA’s clear provisions on Fordow and has potentially severe proliferation implications,” the statement said. “We affirm our readiness to consider all mechanisms in the JCPOA, including the dispute resolution mechanism, to resolve the issues related to Iran’s implementation of its JCPOA commitments.” 

Nov. 12 - Iranian Foreign Minister Mohammad Javad Zarif criticized the European Union’s warning to Tehran over advancements of its nuclear program and accused the Europeans of failing to fulfill their commitments to the 2015 nuclear deal. 

Nov. 16 – Iran informed the IAEA that its stock of heavy water exceeded the 130 metric ton limit under the JCPOA. On the following day, the watchdog confirmed that the Heavy Water Production Plant was active and that Iran had 131.5 metric tons of heavy water. Heavy water is often used as a moderator to slow down reactions in nuclear reactors.   

Nov. 18 – Secretary of State Mike Pompeo said the United States would cancel sanctions waivers for projects at Iran’s Fordow nuclear plant effective December 15. “The right amount of uranium enrichment for the world’s largest state sponsor of terror is zero ... There is no legitimate reason for Iran to resume enrichment at this previously clandestine site,” Pompeo said. The waivers had allowed foreign firms to work on Iran’s civil nuclear program without penalties.  

Nov. 22 - The U.S. Treasury sanctioned Iran’s communications minister, Mohammad Javad Azari Jahromi, for his role in internet censorship. Washington blamed Jahromi’s ministry for blocking internet access in the country for several days in November during widespread protests sparked by a sudden fuel price hike.    

Nov. 27 - French Foreign Minister Jean-Yves Le Drian warned that Paris would consider activating the dispute mechanism of the 2015 nuclear deal, which could eventually trigger U.N. sanctions against the Islamic Republic. “Every two months, there is another dent (in the deal by Iran) to the point where today we ask ourselves, and I’m saying this very clearly, about the implementation of the dispute resolution mechanism that exists in the deal,” he said.  

Dec. 3 - Rafael Mariano Grossi, the incoming chief of the U.N. nuclear watchdog, said the agency was still awaiting an explanation from Tehran after detecting uranium at an undeclared site. Israel and the United States had urged the IAEA to investigate a “secret atomic warehouse,” which Israeli Prime Minister Benjamin Netanyahu revealed during his 2018 U.N. address. “The process continues,” Grossi said. “We have so far not received an entirely satisfactory reply from them, but the exchanges continue.”  

Dec. 4 - President Rouhani said that Iran was still open to nuclear negotiations with the United States. He stipulated that Washington must first remove all sanctions imposed on the Islamic Republic. “If America lifts the sanctions, we are ready to talk and negotiate, even at the level of heads of the 5+1 countries (major powers that were party to the 2015 nuclear deal),” Rouhani said.  

Dec. 6 - European countries condemned Iran’s violations of the 2015 nuclear deal but said the JCPOA was “still alive.” During the nuclear discussions, Tehran told European powers that it would continue to breach the deal until it served Iran’s interests. Iran had breached the JCPOA at least four times since July.  

Dec. 8 - Xiyue Wang, a U.S. citizen detained in Iran since August 2019, was released in exchange for Massoud Soleimani, an Iranian national held in an Atlanta prison for allegedly violating U.S. sanctions. Wang, a Princeton University graduate student, was arrested while conducting research in Iran on the administrative and cultural history of the late Qajar dynasty for his doctoral dissertation. President Trump, Secretary of State Mike Pompeo, and Iranian Foreign Minister Mohammad Javad Zarif thanked the Swiss for their help in arranging the trade. 

Dec. 19 - President Rouhani said that Iran would begin to test a new type of advanced centrifuge. Use of advanced centrifuges to enrich uranium would be a violation of the 2015 nuclear deal. Tehran had already breached the agreement five times since July 1. “We have had great achievements and today, Iranian new IR-6 centrifuges are working and models IR-9 are currently being tested.”  

Dec. 20 — President Rouhani met with Prime Minister Abe in Tokyo to discuss deepening economic ties and tensions over the 2015 nuclear deal. Rouhani reportedly asked Abe to help maintain the 2015 nuclear deal, which the United States withdrew from in May 2018. Rouhani said that a sustainable deal could be secured through “the logic of negotiation and a win-win prospect.” Abe expressed concern over rising tensions in the Middle East and urged Iran to comply with the nuclear deal.  He also urged Tehran to comply with investigations by the U.N. nuclear watchdog.   



Jan. 3 - President Trump ordered an airstrike on a convoy of Iranian and Iraqi military leaders leaving Baghdad airport. The drone attack, launched on January 3 (January 2 U.S. time), killed seven people including General Qassem Soleimani, the head of the IRGC's elite Qods Force, and Abu Mahdi al Muhandis, a Kataib Hezbollah leader. Muhandis was also the deputy commander of the Popular Mobilization Forces (PMF), an umbrella group of militias formed to fight ISIS. Many PMF militias have received arms, training and funding from Iran.    

Jan. 5 -  Iran announced that it would no longer abide by restrictions on uranium enrichment imposed by the 2015 nuclear deal. “The Islamic Republic of Iran, in the fifth step in reducing its commitments, discards the last key component of its operational limitations in the JCPOA, which is the limit on the number of centrifuges,” the government said. Tehran emphasized that all its actions were reversible and that it would return to the deal if sanctions would be lifted and its interests could be guaranteed. Iran said it would continue to cooperate with IAEA inspectors. 

Jan. 8 - Iran fired more than a dozen missiles at two Iraqi military bases housing U.S. troops in retaliation for the U.S. killing of Soleimani. No U.S. or Iraqi personnel were harmed, according to initial reports. Iran was quick to claim responsibility for the attack on U.S. forces. But its foreign minister also emphasized that Tehran did not seek war.   

Jan. 10 - President Trump issued an executive order authorizing sanctions “against any individual or entity operating in the construction, manufacturing, textiles, or mining sectors of the Iranian economy.” Mining and metals have historically been one of the regime's largest non-oil sources of export revenue, some 10 percent. The U.S. Treasury also blacklisted eight senior Iranian officials, including Secretary of the Supreme National Security Council Shamkhani. 

Jan. 14 - Britain, France and Germany triggered the dispute resolution mechanism under the 2015 nuclear deal. It was the strongest action taken by European powers to enforce the agreement. If Iran does not return to compliance, the process could result in the reimposition of U.N. sanctions and ensure that an arms embargo does not expire in October 2020. On the following day, President Rouhani responded defiantly. In recent days I... made it clear to two European leaders that what we have done is reversible for one, and that everything we do regarding the nuclear issue is under the supervision of the IAEA,” Rouhani said. “If you take the wrong step, it will be to your detriment. Pick the right path. The right path is to return to the nuclear deal. 

Jan. 16 - President Rouhani announced that Iran had begun enriching more uranium than before the 2015 nuclear deal. He did not detail how much more uranium was being enriched. Rouhani added that the country’s nuclear program was better off today than before the deal. 

Jan. 17 - The United States blacklisted a Revolutionary Guards commander for his involvement in the crackdown on demonstrators in November 2019. Brigadier General Hassan Shahvarpour “oversaw the massacre of 148 helpless Iranians in the Mahshahr region,” U.S. Special Representative for Iran Brian Hook told reporters. Hook said information about Shahvarpour and other regime officials came from some 88,000 tips received by the State Department from Iranians. 

Jan. 23 - The U.S. Treasury Department designated four companies accused of purchasing Iranian oil and petrochemical products in violation of U.S. sanctions. Two companies based in Hong Kong, one company based in Shanghai and another company based in Dubai allegedly helped Iran’s state-owned oil company export millions of dollars’ worth of petroleum products. The United States also sanctioned Ali Bayandrian, who is linked to Hong Kong-based Triliance Petroleum, and Zhiqing Wang, who has ties to Shandong Oiwangwa. 

Jan. 25 - Ali Asghar Zarean, an aide to Iran’s nuclear chief, said the country had accumulated 1,200 kilograms of low-enriched uranium, far more than the 202.8-kilogram limit under the JCPOA. The announcement suggested Tehran had significantly ramped up enrichment since November, when the IAEA said the stockpile was 372.3 kilograms. 

Jan. 30 - The United States announced sanctions on the Atomic Energy Organization of Iran (AEOI) and its chief, Ali Akbar Salehi. The AEIO has played a big role in Iran breaching its key nuclear commitments [under the 2015 nuclear deal],” Hook said. “It has exceeded the limits on its uranium stockpile and enrichment levels. The head of AEOI personally inaugurated the installation of new advanced centrifuges to expand its uranium enrichment capacity.”  

The United States also renewed sanctions waivers on Iran’s nuclear projects for 60 days. The waivers allowed Russian, Chinese and European companies to continue work on the Arak heavy-water research reactor, the Bushehr nuclear power plant, the Tehran Research Reactor and several other joint initiatives. 

Feb. 3 - Iranian President Hassan Rouhani said that Tehran would bar U.N. inspectors from nuclear facilities if the country were faced with “a new situation.” The warning came during a visit with the Josep Borrell, the new E.U. foreign affairs chief. 

Rouhani added that Iran was willing to negotiate with European powers. “The Islamic Republic of Iran is still ready for interaction and cooperation with the European Union for resolving issues and, whenever the opposite side completely upholds their commitments, Iran will return to its commitments,” he said. 

Feb. 4 - The European Union said that it would avoid sending a dispute over the 2015 nuclear deal to the U.N. Security Council. “We are in agreement not to go directly to a strict time limit which would oblige (us) to go to the Security Council,” said E.U. foreign affairs chief Josep Borrell during a two-day trip to Tehran. After Britain, France and Germany triggered the deal’s dispute mechanism, the parties technically had a 15-day period to resolve issues with Iran. 

Feb. 20 - U.S. Special Representative for Iran Brian Hook announced sanctions on five key members of Iran’s Guardian Council, an unelected panel of twelve Islamic jurists and scholars. The council disqualified more than 9,000 out of the some 14,000 candidates who registered to run in parliamentary elections, scheduled for February 21. Hook dismissed the poll as “political theater” because “the real election took place in secret long before any ballots were cast.” 

Feb. 25 - The U.S. State Department announced sanctions on 13 foreign companies and individuals for supporting Iran's missile program. The entities were based in China, Iraq, Russia, and Turkey. The State Department said that the action was based on a periodic review required under the Iran, North Korea, and Syria Nonproliferation Act. “The imposition of sanctions against these foreign entities is consistent with our efforts to use all available measures to prevent Iran from advancing its missile capabilities,” the State Department said in a statement. 

Mar. 3 - The IAEA released a pair of reports that lambasted Iran for violations of the JCPOA. In the first report, the U.N. nuclear watchdog found Iran had tripled its stockpile of low enriched uranium since its last quarterly report. The larger stockpile could shorten Iran’s breakout time – the time it would take to produce enough fissile material for a nuclear weapon. But the IAEA did not find evidence that Iran was taking steps toward producing a weapon. In the second report, the IAEA condemned Iran’s refusal to grant inspectors access to three sites of interest. The report said that it found evidence from early July 2019 that was consistent with efforts “to sanitize part of the location” to obscure nuclear material.   

Mar. 17 - The State Department designated nine companies in South Africa, Hong Kong and China, as well as three Iranian nationals, for “the purchase, acquisition, sale, transport, or marketing of petrochemical products from Iran” in violation of U.S. sanctions. The Department of Commerce separately designated 18 corporations and six individuals— including five Iranian nuclear scientists — for assisting with Iran’s nuclear program, Pakistan’s unsafeguarded nuclear and missile programs, and Russian military modernization efforts. 

Mar. 25 - Iran and seven other countries urged U.N. Secretary General Antonio Guterres to call for the immediate lifting of unilateral sanctions imposed mainly by the United States and the European Union. In a joint letter, the foreign ministers of China, Cuba, North Korea, Iran, Nicaragua, Russia, Syria, and Venezuela said fighting the COVID-19 pandemic was “hard – if not impossible” under the limitations imposed by sanctions. They urged the U.N. chief to "reject the politicization of such a pandemic" and immediately call for the removal of the "illegal, coercive measures of economic pressure." 

Mar. 26 - The United States sanctioned 20 individuals and companies for funneling money to the Islamic Revolutionary Guards Corps-Qods Force (IRGC-QF) and transferring lethal aid to Iraqi militias backed by Iran. “Iran employs a web of front companies to fund terrorist groups across the region, siphoning resources away from the Iranian people and prioritizing terrorist proxies over the basic needs of its people,” said Treasury Secretary Steven T. Mnuchin. 

April 15 - The United States accused Iranian military vessels of conducting “dangerous and harassing” maneuvers close to U.S. Navy and Coast Guard ships in the Persian Gulf. A group of 11 speedboats belonging to the IRGC repeatedly approached six U.S. military vessels at close range and at high speeds, coming within 10 yards of one ship, the Pentagon said. The U.S. warships were conducting joint training operations with U.S. Army helicopters in international waters. The United States issued several warnings, including bridge-to-bridge radio communications, blasts from the ships’ horns, and soundwaves from long-range acoustic devices. The Iranian vessels left after an hour. 

April 20 - Iranian Foreign Minister Javad Zarif met with Syrian President Bashar Assad and Foreign Minister Walid Moallem in Damascus. The high-level meeting was Zarif’s first trip abroad in nearly two months and his first to Syria since April 2019. Assad expressed his “condolences” over the thousands of Iranians killed by the virus. Both Iran and Syria condemned the U.S. for not lifting its sanctions during a global pandemic.  

May 19 - The U.S. Treasury sanctioned a China-based company for providing services to Mahan Air, an Iranian airline blacklisted in 2011 for supporting the elite Qods Force. Mahan Air has transported fighters, weapons, equipment and funds to support the Syrian regime and Iranian proxies across the Middle East, including Hezbollah. Shanghai Saint Logistics Limited was the seventh company sanctioned for acting as a general sales agent for Mahan Air. 

May 20 - The United States sanctioned nine Iranian officials, including the interior minister, and three entities for human rights abuses. The new measures “send a message of support to the Iranian people that we will continue to support their demands for transparent and accountable governance and speak out for those who are being silenced by this regime,” said Secretary of State Mike Pompeo. The State Department imposed visa restrictions and the Treasury Department imposed financial sanctions. 

May 27 - The Trump Administration announced that it would end waivers – or exemptions from U.S. sanctions – allowing British, Chinese and Russian companies to work at three Iranian nuclear sites. The work focused on ways to contain or limit Iran’s ability to use its nuclear program to build a bomb. The foreign projects were part of the 2015 nuclear deal between Iran and the world’s six major powers. Foreign companies involved were given 60 days to wind down activities on three projects—or face U.S. sanctions. 

June 2 - Iranian Foreign Minister Mohammad Javad Zarif announced that Sirous Asgari, a scientist who had been imprisoned in the United States, was on a plane back to Iran. “Congratulations to his wife and his esteemed family,” he wrote on Instagram. Dr. Asgari was indicted in 2016 on charges of stealing trade secrets related to research he had done at Case Western Reserve University in 2012 and 2013. The scientist, an engineer who specializes in metals and materials, had been working on a project for the U.S. Navy Office of Naval Research to create anti-corrosive stainless steel. 

June 4 - Iran released Michael White, an American who had been detained for nearly two years. The U.S. Navy veteran was arrested on unspecified charges in July 2018 while visiting his girlfriend in Iran. In March 2019, White was sentenced to two years in prison for insulting the supreme leader and 10 years for posting a private photograph on social media. In March 2020, White – an immunocompromised cancer patient – was released from prison on medical furlough and transferred to a hospital with COVID-19 symptoms. As White was released, the United States freed an Iranian doctor, Majid Taheri, who was charged with violating U.S. sanctions on Iran. Prosecutors said he tried to export a filter to Iran that could be used for chemical and biological warfare. But Taheri, who also holds U.S. citizenship, claimed it was for vaccine research. He arrived in Iran on June 8.  

June 8 - The United States expanded sanctions on Iran’s shipping industry. The Treasury Department blacklisted Islamic Republic of Iran Shipping Lines (IRISL) and its Shanghai-based subsidiary, E-Sail Shipping Company Ltd, along with more than 100 ships and tankers. “IRISL has repeatedly transported items related to Iran’s ballistic missile and military programs and is also a longstanding carrier of other proliferation-sensitive items,” including items that can be used in Iran’s nuclear program, Secretary of State Mike Pompeo said. 

August 14 - A U.S. resolution that would require all U.N. member states to indefinitely forbid the sale of conventional arms to Iran failed at the Security Council. The vote in the 15-member body was only two in favor (the United States and the Dominican Republic), two against (Russia and China), and 11 abstentions. To win passage, any Security Council resolution needs nine votes in favor and no vetoes from the Council’s five permanent members—Britain, France, China, Russia and the United States. 

August 17 - Iran offered bounties to Taliban fighters to target U.S. forces and coalition troops in Afghanistan, CNN reported. The payments were linked to at least six attacks last year by the Haqqani network, including one on Bagram Air Base that killed two civilians.  

Sept. 13 -  As a presidential candidate, Joe Biden pledged that he would “offer Tehran a credible path back to diplomacy” if elected. “If Iran returns to strict compliance with the nuclear deal, the United States would rejoin the agreement as a starting point for follow-on negotiations,” Biden wrote in September 2020. “With our allies, we will work to strengthen and extend the nuclear deal's provisions, while also addressing other issues of concern,” such as ballistic missiles and Iran’s regional proxies.

October 18 - The global ban on the sale of conventional arms to Iran expired and opened the way for the Islamic Republic to import weapons, including warplanes, helicopter gunships, missiles, tanks, artillery, and other weapon systems. The ban was imposed by U.N. Resolution 1929 in 2010. It was lifted as part of the 2015 nuclear deal—enshrined in U.N. resolution 2231—as one of the incentives for Tehran to cooperate on its nuclear program. Iran was also allowed to export its domestically produced arms for the first time in a decade.  



Feb. 1 - Iranian Foreign Minister Mohammad Javad Zarif suggested that the European Union could “choreograph” moves by the United States and Iran to return to the Joint Comprehensive Plan of Action (JCPOA). ”There can be a mechanism to basically either synchronize it or coordinate what can be done,” he told CNN.

Feb. 7 - President Biden reaffirmed in a CBS interview that his administration would not lift sanctions first to entice Iran back to the negotiating table.

Feb. 10 - Special Envoy for Iran Malley spoke with China’s vice foreign minister Ma Zhaoxu to discuss Iran’s nuclear program, Beijing said in a phone call readout.

Feb. 18 - The Biden administration announced three opening moves to jumpstart diplomacy with Iran. The three moves were accepting an invitation from the E.U. to attend a meeting of the P5+1 countries, rescinding the Trump administration invocation of “snapback” sanctions at the United Nations, and lifting travel restrictions on Iranian diplomats in New York.

Feb. 19 - Tehran reacted coolly to the U.S. offer of talks and instead repeated its demand  that Washington lift all sanctions imposed by the Trump administration between 2018 and 2021 as a precondition to roll back its breaches of the 2015 nuclear deal. “Gestures are fine. But to revive P5+1, US must Act: LIFT sanctions,” Foreign Ministry spokesperson Saeed Khatibzadeh tweeted. “Here is the key sequence: #CommitActMeet.

Feb. 28 - Iran rejected an E.U. offer to broker direct talks with the United States. “Given the recent moves and positions of the U.S. and the three European countries, the Islamic Republic doesn’t assess the timing of an informal meeting proposed by the E.U. coordinator as appropriate,” the foreign ministry said.

March 27: Iran and China signed a 25-year "strategic partnership" to deepen economic and security ties. The text of the agreement was not published, but a draft released in June 2020 indicated that Beijing would invest billions in exchange for a heavily discounted supply of Iranian oil. "We want China to continue to be a major trading partner to Iran and to have more cooperation in the field of joint ventures," President Hassan Rouhani said

March 30 - The Biden administration would be willing to discuss a comprehensive “roadmap” for both the United States and Iran to fully return to the nuclear deal rather than limited initial steps, a U.S. official told Reuters. “If that’s what Iran wants to talk about, we are happy to talk about it,” the official said.

April 1 - The European Union said that it would host a virtual meeting to discuss the “possible return of the United States to the JCPOA” with the remaining five participants of the deal, including Iran. State Department spokesperson Ned Price welcomed the meeting as a “positive step, especially if it moves the ball forward on that mutual return to compliance.”

April 2 - The United States and Iran said that they would both attend diplomatic talks in Vienna the following week to discuss the JCPOA but would not meet directly. The Vienna meeting would focus on reaching two separate agreements: one with the United States on its timetable for lifting sanctions and one with Iran on its timetable for returning into compliance, The Wall Street Journal reported. Malley told PBS that the U.S. delegation would also push for the return of American detainees in Iran, "whatever happens on the nuclear side, whether we succeed or fail."

April 6 - Indirect talks between the United States and Iran began in Vienna. Two expert working groups were formed: one on the timetable for lifting U.S. sanctions on Iran, the other on reversing Iran's breaches of the nuclear deal. Araghchi said that negotiations were on "the right track," but that it was "too soon to say it has been successful."

April 9 - The first week of talks in Vienna concluded. No final agreement was reached, but participants agreed to reconvene the following week. The P4+1 "took stock of the work done by experts over the last three days and noted with satisfaction the initial progress made," Ambassador Ulyanov tweeted

Iran and Saudi Arabia held direct talks five years after severing diplomatic relations. The talks in Baghdad were mediated by Iraqi Prime Minister Mustafa al Kadhimi. The Iran delegation was led by Saeed Iravani, deputy secretary of the Supreme National Security Council. The Saudi delegation was led by Khalid al Humaidan, the chief of intelligence. The discussion focused primarily on Yemen, where Riyadh and Tehran have backed opposing sides since the civil war erupted in 2014. The delegations also reportedly discussed the political and financial crisis in Lebanon, where Iran and Saudi Arabia back opposing political blocs.

April 15 - Indirect talks over getting the United State and Iran back into compliance with the JCPOA resumed in Vienna. In Tehran, President Rouhani reiterated that Iran was not seeking a nuclear weapon. “We can enrich 90 percent today, but we stand by our word and we are not looking for an atomic bomb,” he said during a cabinet meeting. “It is YOU who made and stockpiled the atomic bomb and are still making bombs. This is what YOU do. Do not accuse us of making bombs, Iran's activities are completely peaceful.”

April 20 - The Joint Commission created a third expert group "to start looking into the possible sequencing of respective measures" by the United States and Iran to reenter the JCPOA. Diplomatic talks in Vienna paused to give delegations time to consult with their capitals. Parties would resume discussions the following week. "There has been some progress, but there remains a long road ahead," State Department spokesperson Ned Price said. "And I think it’s fair to say that we have more road ahead of us than we do in the rearview mirror."

April 21 - Iran and Saudi Arabia would hold a second round of direct talks in late April or early May, Reuters reported. The timing of the second meeting would depend on progress in Vienna negotiations between Iran and the six world powers on returning to the Joint Comprehensive Plan of Action (JCPOA).

April 27 - Talks resumed in Vienna for the third round. 

May 1 - The Joint Commission wrapped up the third week of Vienna talks. "Moderate advances but with more detail comes more complexity," E.U. Coordinator Mora tweeted. "We will reconvene next week to continue." Ambassador Ulyanov said that participants aimed to complete talks to restore the JCPOA in three weeks. 

May 2 - White House Chief of Staff Ron Klain denied media reports that Iran had agreed to release four American detainees. "We're working very hard to get them released," he said on CBS Face the Nation. "We raised this with Iran and our interlocutors all the time. But so far there's no agreement to bring these four Americans home."

May 6 - Talks resumed in Vienna for the fourth round.

May 10 - Iran confirmed that it was holding talks with Saudi Arabia. “We welcome resolving of the issues that have existed between the two countries,” Foreign Ministry spokesperson Khatibzadeh said during a weekly press conference. “We will use our best efforts in this regard.”

May 10 – 20: Iranian leaders offered unequivocal support after Palestinian militants in Gaza fired rockets at Israeli cities, and Israel responded with airstrikes on May 10. Khamenei called on Palestinians to “confront the enemy” and “stand strong” against Israel. “One can only talk with the language of strength with these criminals,” he said in a video message on May 11. Foreign Minister Mohammad Javad Zarif released a video in Arabic on May 11 condemning Israel as “racist” and calling for a “popular referendum” to determine the future of the Holy Land.   

May 12 - Foreign Minister Mohammad Javad Zarif said that Iran was "ready for close ties with Saudi Arabia" and that greater cooperation could help stabilize the region, including Yemen. His remarks followed a meeting with President Bashar al Assad during a visit to Syria. “I am sure our Syrian brothers have always welcomed cooperation in the Arab world," Zarif added. "And we are also in that mood.”

May 16 - Secretary of the Supreme National Security Council Shamkhani said that Iran would work with its neighbors to bolster regional security. "We're ready to participate with the countries of region in a mechanism to create collective security as an infrastructure for development & welfare of their nations," he tweeted

May 17: President Hassan Rouhani told Iraqi Prime Minister Mustafa al Kadhimi that he welcomes Baghdad's role as a regional mediator. "Dr. Rouhani also expressed support for Iraq's role in regional interactions as an important member country of the Arab League, welcoming Baghdad's positive role in intervening to resolve disputes among regional states," according to a phone call readout released by the president's office. 

May 18 - The Saudi foreign minister expressed optimism about the talks with Iran, AFP reported. "We have initiated some exploratory talks," Foreign Minister Prince Faisal bin Farhan said while in Paris. "They are at a very early stage, but we are hopeful." The result of the Iranian presidential election, slated for June 18, was unlikely to affect the talks, he added. "Our understanding of Iran's foreign policy is that it's set by the Supreme Leader," he said. "So we don't think there will be a substantial change."

May 19 - The Joint Commission met in Vienna and concluded the fourth round of talks. "We’ve made good progress. An agreement is shaping up," Mora tweeted after the meeting. "Significant" progress was reached and an agreement was "within reach," according to Ambassador Ulyanov. "Hopefully the 5th round will be final," he tweeted.

May 20 - Israel and Hamas agreed to an Egypt-brokered ceasefire that went into effect the next morning. On May 21, Khamenei congratulated the Palestinians on their “victory” over Israel. “Greetings to the heroic, resistant Gaza. Greetings to Hamas, Islamic Jihad and all jihadi and political groups in Palestine,” he wrote. “The savage, wolf-like enemy has realized correctly that it is powerless when facing the unified uprising of Palestine.” 

May 21 - Foreign Minister Zarif spoke with E.U. foreign policy chief Josep Borrell to discuss the state of the talks. "All sides now need to take necessary political decisions, so we can conclude negotiations & get back to full implementation," Borrell tweeted

May 25 - Talks resumed in Vienna for the fifth round. 

June 2 - The fifth round of talks in Vienna ended. Differences between the parties were "not insolvable," according to Iran's deputy foreign minister. "I do not think there will be much delay between today's meeting and the next round of talks," Araghchi said. "Like in the previous rounds, we will probably return to Vienna after consulting with our capitals."

June 12 - Talks resumed in Vienna for the sixth round.

June 18 - Araghchi met with IAEA chief Grossi in Vienna, according to Iran’s envoy to the U.N. nuclear watchdog. The pair discussed the latest developments around the JCPOA negotiations and possible assistance of the [IAEA]," Ambassador Gharibabadi tweeted

June 20 - The sixth round of talks in Vienna concluded. Delegations returned to their respective capitals for consultations.  

June 21 - President-elect Ebrahim Raisi warned that his administration would take a harder stand on diplomacy with the international community. “The world, particularly the West, should realize that the situation in Iran has changed through the people’s vote,” Raisi told reporters on June 21. He specifically rejected negotiations to limit either Iran’s regional role or its ambitious missile program, although he expressed support for the 2015 nuclear deal brokered with the world’s six major powers. 

July 6 - An Iranian government spokesperson said that "good progress" had been achieved in talks with Saudi Arabia but cautioned against expecting a swift diplomatic breakthrough. "In some cases, disputes may have complexities that take time to resolve," Ali Rabiei told reporters.

July 7 - The State Department said that it had "every expectation that there will be a seventh round of talks" in Vienna. "The team continues to remain here, continues to engage in discussions, continues to do important work from the department, but that team will be ready, will be prepared to travel back to Vienna when there’s a seventh round of talks," department spokesman Ned Price told reporters in Washington D.C.

Foreign Minister Mohammad Javad Zarif hosted peace talks with Sher Mohammad Abbas Stanikzai, the Taliban’s chief negotiator, and former Vice President Younus Qanooni representing the Kabul government. Zarif urged them to “take difficult decisions today for the future of their country.” Iran was “ready to assist the dialogue” and to “resolve the current conflicts in the country” following the “failure of the U.S. in Afghanistan,” he said. Zarif subsequently tweeted that the meeting had been “cordial” and promised Iran would stand with Afghans on their road to peace.

July 12 - The State Department said that the U.S. delegation was "prepared to return" to Vienna for a seventh round of talks "as soon as they are scheduled." 

July 13 - Iran confirmed that it was negotiating a prisoner exchange with the United States. "‌Because of its humanitarian aims, Iran is ready to exchange all American political prisoners in exchange for the release of all Iranian prisoners who have been detained around the world at the behest of America," government spokesperson Ali Rabiei said.

July 14 - Iran informed European diplomats that it would not be ready to resume negotiations in Vienna until after Raisi was inaugurated as the new president in August, Reuters reported. "We were prepared to continue negotiating, but the Iranians requested more time to deal with their presidential transition," a State Department spokesperson said. 

The State Department warned that the U.S. offer to return to the nuclear deal was not "indefinite" and urged a swift return to negotiations. "There will come a point where our calculus will change, where the gains that Iran is able to make in its nuclear program, the benefits it accrues might one day outweigh the benefit that the international community would accrue from a mutual return to compliance with the JCPOA," Ned Price told reporters at a press briefing. "We’re not there yet, but that is why we believe we should...return to Vienna for these talks just as soon as we can.

July 17 - Araghchi said that Iran would not return to Vienna for a seventh round of talks until after Raisi’s inauguration. “We’re in a transition period as a democratic transfer of power is underway in our capital,” he tweeted. State Department spokesman Price condemned the delay as “outrageous.” 

The delay also postponed a potential deal for the safe return of American and British detainees in Iran in exchange for Iranian detainees in the United States and Britain. Araghchi said that up to 10 prisoners “on all sides” could be released immediately, if the Biden administration made a decision to act. But State Department denied that any detainee exchange had been agreed. “We see just another cruel effort to raise the hopes of their families,” Price said.

July 30 - In one of his last acts as foreign minister, Zarif published a 204-page book titled “Documenting Six Years of Western (Non-) Implementation of the ‘Iran Nuclear Deal.’” The book included his last letter to U.N. Secretary General Antonio Guterres, dated July 20, in which he accused the United States and its “European accomplices” of failing to comply with the deal. Zarif claimed that the Britain, France, Germany and the United States were using economic pressure and blackmail to renegotiate provisions of the agreement, including the timetable for restrictions on Iran to expire.   

August 4 - Deputy Foreign Minister Araghchi met with E.U. coordinator Mora in Tehran to discuss Afghanistan, E.U.-Iran relations and the nuclear talks in Vienna. Mora's "key priority is to resume negotiations in Vienna and facilitate the way back to full JCPOA implementation," E.U. external affairs chief Josep Borrell said

August 8 - The U.N. secretary general’s envoy for Afghanistan, Jean Arnault, met with Zarif in Tehran. They agreed that intra-Afghan talks were the best way to stem the violence between Afghan government forces and the Taliban.

August 5 – The United States called on Iran’s new president, Ebrahim Raisi, to resume talks on restoring full U.S. and Iranian compliance with the 2015 nuclear deal. “We urge Iran to return to the negotiations soon so that we can seek to conclude our work,” State Department Spokesperson Ned Price said. He added that the window of opportunity to return to the nuclear deal “won’t last forever,” reiterating a similar warning by Secretary of State Antony Blinken on July 29. 

August 11 – President Raisi nominated Hossein Amir-Abdollahian, a hardliner, as his foreign minister. Amir-Abdollahian previously served as deputy foreign minister for Arab and African affairs and has close ties to the Revolutionary Guards, the Financial Times reported.

August 17 – Iran was using a second cascade of centrifuges to enrich uranium to nearly weapons-grade level, the IAEA reported. Tehran added a cascade of 153 advanced IR-4 centrifuges to enrich uranium up to 60 percent, according to a report by the U.N. nuclear watchdog. Uranium needs to be enriched up to 90 percent to fuel a nuclear bomb. In April, began enriching uranium to 60 percent, the highest level of enrichment that it has publicly acknowledged. In May, the IAEA had reported that Iran was using 164 IR-6 centrifuges to enrich uranium up to 60 percent.

August 23 – Iran announced that it would resume exporting fuel to Afghanistan at the Taliban’s request. The price of gasoline had exceeded $900 per ton in Afghanistan due to a spike in demand from Afghans fleeing Taliban-controlled cities.

The goal was to ease regional tensions, particularly between Iran and the Arab nations. Iran, which is predominantly Persian, is one of only two countries in the Middle East that is not ruled by Arabs. It was Amir-Abdollahian’s first trip abroad as foreign minister.

August 31 – Foreign Minister Amir-Abdollahian tweeted that he had a “positive” and “cordial” meeting with Sheikh Mohammed bin Rashid Al Maktoum, the prime minister of the United Arab Emirates (UAE), on the sidelines of the Baghdad Summit on August 28. “Iran and the UAE can take big steps toward cooperation and the realization of neighborhood policy and diplomacy.”

Raisi called for “an end to the bloodshot and fratricide” in the wake of the Taliban takeover. 

September 7 – The IAEA reported that Iran has continued to amass highly enriched uranium above the limits defined in the 2015 nuclear deal. The IAEA’s confidential quarterly report, seen by The Associated Press, stated that its verification and monitoring program was “seriously undermined” by Iran’s refusal, since February 2021, to allow inspectors’ full access to IAEA monitoring equipment.

September 8 – Secretary of State Blinken reiterated that Iran’s continued advances in nuclear technology could jeopardize the restoration of the 2015 nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA). “I’m not going to put a date on it, but we are getting closer to the point at which a strict return to compliance with the JCPOA does not reproduce the benefits that that agreement achieved,” he said.

September 12 – Iran and the IAEA reached an agreement that would allow the watchdog agency to service monitoring equipment at Iranian nuclear facilities. The IAEA had not had access to its equipment, including cameras, since May 25. It urgently needed to swap out memory cards to prevent any data gaps.

September 28 – Foreign Ministry spokesman Khatibzadeh rejected Azerbaijan’s concerns over military drills that Iran conducted along the shared border. He said the exercises were a matter of “sovereignty” and “national security.” Iran “will not tolerate the presence of the Zionist regime near our borders,” he said, an apparent reference to Azerbaijan’s close ties with Israel.

September 30 – Khamenei declared that Iran must “firmly block” the import of South Korean home appliances to protect Iranian producers. “The two [South] Korean companies...will break the back of domestic manufacturers, which have just started to stand on their own feet,” he wrote in a message to President Raisi. Khamenei appeared to be referring to Samsung and LG. 

Israeli Foreign Minister Yair Lapid visited Bahrain and reportedly discussed cooperation on responding to Iranian drone attacks, according to Israeli newspaper Haaretz. Lapid met with Bahrain’s king, prime minister and foreign minister. During the visit, Lapid toured the headquarters of the U.S. Navy’s Fifth Fleet. Iran criticized Bahrain for hosting the Israeli official. “It is unfortunate that Bahrain’s rulers ignore the Zionist regime’s daily crimes against the oppressed but resilient people of Palestine,” Foreign Ministry spokesperson Khatibzadeh said. “This stain will not be erased from the reputation of Bahrain’s rulers.”

October 6 – Foreign Minister Amir-Abdollahian met with his Russian counterpart, Sergey Lavrov, in Moscow to discuss talks on restoring the 2015 nuclear deal as well as developments in Afghanistan, the Caucasus, Syria and Yemen. “Fortunately, ties between Tehran and Moscow are at the best level and I am confident that these relations will expand even more with the coming to office of the new government [in Tehran],” Lavrov said.

October 11 – Microsoft announced that hackers allegedly linked to Iran targeted more than 250 customers “with a focus on US and Israeli defense technology companies, Persian Gulf ports of entry, or global maritime transportation companies with business presence in the Middle East.” Less than 20 of the targets were breached since July. “Gaining access to commercial satellite imagery and proprietary shipping plans and logs could help Iran compensate for its developing satellite program,” Microsoft said in a blog post

October 13 – Iran and Azerbaijan agreed to reduce tensions through dialogue. In a joint statement, their foreign ministers condemned “the harmful rhetoric observed recently, which does not correspond to the level of friendly relations between our countries.” In early October, Iran had held military drills near the shared border that surprised Azerbaijan. Iran also alleged that Israel, which supplies weapons to Azerbaijan, had deployed its forces in the country. Baku rejected the claim. 

Qatari Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani called for dialogue between the Gulf Cooperation Council countries and Iran. “Iran is our neighbour, a player in our region … we cannot change geography. Our disagreements can be resolved around a table, they can’t be resolved by confrontation,” he told the Global Security Forum in Doha. He also expressed hope that the 2015 nuclear deal would be restored “to see that there is no risk of a nuclear race in our region.”

October 19 – IAEA chief Grossi said that the “stop-gap” measures on monitoring Iran’s nuclear facilities agreed to in February were no longer “intact.” In an interview with the Financial Times, Grossi said that Iran was not permitting surveillance cameras at the Tesa Karaj facility, which produces parts of centrifuges that can enrich uranium.

October 25 – Iran began feeding uranium gas enriched to 20 percent into a single IR-6 centrifuge at the Natanz facility outside Isfahan, the IAEA reported. Iran was already enriching small amounts of uranium to 60 percent purity—far above the cap of 3.67 percent set by the JCPOA—at Natanz. Iran was not retaining the enriched uranium, the agency noted, but the move prompted the IAEA to “increase the frequency and intensity of its safeguards activities” at the facility. Uranium enriched to 90 percent or above is considered weapons-grade.

October 27 – Iran’s lead negotiator announced a return to nuclear talks with the world’s six major powers by end of November. Ali Bagheri, the new deputy foreign minister, tweeted the announcement after meeting in Brussels with Enrique Mora, the E.U. coordinator for the talks.

November 2 – Monitoring Iran’s nuclear activities was becoming increasingly difficult, warned Grossi, the head of the IAEA. “I would say we are flying in a heavily clouded sky,” he said. “We can continue in this way, but not for too long,” he added. Iran curtailed the watchdog’s access starting in February 2021.

November 8 – Foreign Ministry spokesperson Khatibzadeh outlined Iran’s demands for the United States ahead of the resumption of nuclear talks on November 29.

November 9 – Foreign Minister Amir-Abdollahian, in a phone call with his French counterpart, expressed a desire to expand bilateral ties. French Foreign Minister Jean-Yves Le Drian said that nuclear talks must resume where they left off on June 20. 

November 17 – The United States and the Gulf Cooperation Council (GCC) condemned Iran for supporting militias and proliferating weapons across the region. Ballistic missiles and drones “have been used by Iran or its proxies in hundreds of attacks against civilians and critical infrastructure in Saudi Arabia and civilian merchant seamen in international waters of the Sea of Oman, and endangered American troops combatting ISIS,” the United States and the GCC said in a statement following a working group meeting in Riyadh, Saudi Arabia.

November 18 – The United States sanctioned six Iranian men and one company, Emennet Pasargad, for attempting to interfere with the 2020 U.S. presidential election.

November 29 – The world’s major powers and Iran opened the seventh round of talks on restoring the 2015 nuclear deal. From April to June 2021, they held six rounds of talks.

October 18 – Ukraine’s foreign ministry proposed cutting ties with Iran for supplying drones to Russia. “The actions of Iran are vile and deceitful,” Foreign Minister Dmytro Kuleba said. “We won’t suffer them, because all those actions were done while Iran told us that they didn’t support the war and won’t support any of the sides with their weapons.”
