As the situation in Iraq worsens, China is showing increasing consternation. And while authorities have mainly issued broad statements of concern, it's no secret what worries those in charge in Beijing: the risks the crisis could pose to its Iraqi-sourced oil supply and China's three petro-majors, all active in the country. While officials may not be so direct, that's not the case with others. The situation in Iraq will almost certainly drive up oil prices for China, which imports about 60% of its crude, Lin Boqiang, director of the China Center for Energy Economic Research at Xiamen University, warned yesterday. So far the conflict has been in the north, away from Iraq's most productive oil fields, which are mainly located in the south.
