"Operation Libya" and the Battle for Oil part 2 by Prof Michel Chossudovsky http://www.globalresearch.ca/index.php?context=va&aid=23605

Foreign oil companies operating prior to the insurrection in Libya include France's Total, Italy's ENI, The China National Petroleum Corp (CNPC), British Petroleum, the Spanish Oil consortium REPSOL, ExxonMobil, Chevron, Occidental Petroleum, Hess, Conoco Phillips. Of significance, China plays a central role in the Libyan oil industry. The China National Petroleum Corp (CNPC) had until its repatriation a Chinese workforce in Libya of 30,000. British Petroleum (BP) in contrast had a British workforce of 40 which ahs been repatriated. Eleven percent (11%) of Libyan oil exports are channelled to China. While there are no figures on the size and importance of CNPC's production and exploration activities, there are indications that they are sizeable. More generally, China's presence in North Africa is considered by Washington to constitute an intrusion. From a geopolitical standpoint, China is an encroachment. The military campaign directed against Libya is intent upon excluding China from North Africa.
