Part of a Kurdish oil cargo has been offloaded from a Greek-managed tanker into another tanker in the South China Sea, but mystery surrounds the identity of the buyer and where the two tankers are headed. The United Emblem, which is carrying more than 1 million barrels of oil, is one of three tankers loaded with oil from the autonomous Kurdish region, which is trying to sell oil independently. Iraqi Kurdistan is locked in a bitter legal and diplomatic struggle with Baghdad over international oil sales. A U.S. judge on Tuesday refused a request by Baghdad, citing a lack of jurisdiction, to seize 1 million barrels of oil aboard the United Kalavrvta tanker, which has been anchored off the port of Galveston since the weekend.
