12 Iranian tankers have transported oil to Asia and the Mediterranean since May 2, when the United States revoked sanctions waivers which had previously allowed eight countries to buy Iranian oil. At least six were unloaded in China, while others went to the Mediterranean through the Suez Canal, likely bound for Turkey or Syria. The National Iranian Oil Company owns or manages 11 out of the 12 tankers. This scale of Iranian oil shipments is larger than was previously known.
