China's central bank chief says trade tensions major risk to global economy

China's top central banker said on Saturday that potential escalation of trade tensions and policy uncertainty were the major risk factors facing the world economy, and market forces were keeping China's yuan at an appropriate level.

Yi Gang, the governor of the People's Bank of China, said in a statement to the International Monetary Fund's steering committee that Beijing is "deeply disappointed" in the IMF's failure to realign its shareholding structure to recognize the rising influence of China and other fast-growing economies.
