China must match foreign policy to global role

Academic Yan Xuetong says China must adapt its "low profile" foreign policy to its increasing global role. The director of the Institute of International Studies at Tsinghua University tells China bureau chief Geoff Dyer that, because of their nuclear weapons, there is no danger of war between the US and China, and that the tensions in 2010 between China and other Asian countries were "only slight'. But he sees growing tension with the US as inevitable.
