After the failed Unocal Corp. bid in 2005, China's policy has shifted to taking minority stakes, not taking an active role, and keeping Chinese managers at a distance from U.S. advanced technology.

By buying a small stake in a company Chinese government advisors see the opportunity to to get an entry into new markets and gain the exerience and knowledge needed to keep up with new drilling techniques. This comes at a time when China expects to become the world's largest oil consuming country because of the surging use of automobiles in the country, according to the International Energy Agency. Natural gas consumption doubled in China between 2006 and 2010 according to the BP Statistical Review.
