"But while others back out, Chinaoil has sold a total of about 600,000 barrels worth around $55 million to the Islamic Republic. The cargoes were Chinaoil's first direct sales to Iran since at least January 2009, according to Reuters data. Chinese firms have previously sold through intermediaries, traders said. 'Prior to this there was some third-party trades going on, but this was a direct sell,' a trader said. Chinaoil is the trading unit for China's top energy group China National Petroleum Corp (CNPC), which is the parent of U.S. and Hong Kong-listed PetroChina (0857.HK) (PTR.N). A CNPC spokesman was unable to comment on the sales." (Reuters, "Exclusive: China's top oil firms sell gasoline to Iran-trade," 4/14/10)
