On June  28, the United States reported that China cut its imports of Iranian oil  by 25 percent to avoid U.S. sanctions. What impact will the cutback  have on China-Iran relations, both economically and politically?
  Politically,  the exemption from the Obama administration is not necessarily  that damaging for China-Iran relations. While China’s relationship with  the United States is Beijing’s most important bilateral relationship,  the Chinese government would also like to preserve a good working  relationship with Tehran. The fact that the Chinese government did not  publicly promise to reduce oil imports from Iran to secure an exemption  from U.S. sanctions gives Beijing some room to maneuver. 
  Beijing  can tell Tehran that it opposes the sanctions--and that the U.S.  exemption does not reflect China’s support for U.S. sanctions. It can  note that the reduction is due instead to a contract dispute earlier  this year between Sinopec, the largest Chinese importer of Iranian  crude, and the National Iranian Oil Company.  As a result of this  contract dispute, China’s oil imports from Iran fell by more than  one-third in the first quarter of 2012. 
Economically,  China’s cutbacks are having an impact on the Iranian economy, as are  reductions made by other countries.  Iran’s crude oil exports have  fallen from 2.5 million barrels per day (bpd) in 2011 to 1.5 million  bpd, which implies revenue losses of $8 billion per quarter, according  to the International Energy Agency.
Moreover,  unilateral sanctions by the United States, the European Union, Japan and  other countries in 2010 have constrained China’s national oil companies  in Iran.  Since these sanctions were imposed, Washington repeatedly  warned Beijing that it opposed Chinese companies taking over oil and  natural gas projects abandoned by European and Japanese  companies.  China’s companies have not taken over any of these  projects. 
  What will China’s cutback mean for Iran’s economy? Can China find alternative oil imports on a long-term basis?
China  can find alternative oil imports. Earlier this year, for example,  Sinopec was not buying from Iran due to its contract dispute with  National Iranian Oil company. So China it bought more oil from Russia  and Vietnam. Going forward, China should be able to continue to find oil  supplies to replace future reductions in its imports from Iran. Saudi  Arabia has increased its output; Libya is back on-line; and oil  production is growing in Iraq and the United States.  The decline in  U.S. imports of light crudes from Africa due to increased domestic  production, in theory, frees these crudes for sale to China. 
  The  U.S. waiver of sanctions on China is good for only 180 days. China must  cut back even further on its Iran oil imports to continue to get the  U.S. waiver in six months. Is Beijing likely to comply? Why or why not?
  It  will probably be more challenging for China to secure another exemption  in six months. The reduction in China’s imports of Iranian crude during  the first five months of this year were due largely if not entirely to  the contract dispute between Sinopec and National Iranian Oil Company.  The contract dispute, which began in late 2011, was resolved in March  2012.  As a result, China’s oil imports from Iran began to rise in  April, and by May, China’s oil imports from Iran were back to 2011  levels of more than 500,000 bpd.
Sinopec has  said it plans to buy 16 to 20 percent less from Iran in 2012. But most  of those reductions have already occurred. If China continues to buy at  2011 levels this year, then China is unlikely to satisfy the U.S.  criteria of “significant reduction in Iranian crude oil purchases” for  another 180-day sanctions exemption. 
  China  is the largest importer of Iranian crude oil. China accounted for 22  percent of Iran’s oil exports in the first half of 2011, averaging  543,000 bpd. How much Iranian oil can China cut back realistically  without hurting its own economic growth?
China  has reduced its Iranian oil imports by 25 percent from January to May  2012 without any adverse effects to its economy. There are other sources  of supply, which could replace future reductions in China’s oil  purchases from Iran.  Sinopec may be reluctant to change the mix of  crudes in its refineries, but it would not be that difficult for Sinopec  to do so.
