China lodges complaint over Trump-Taiwan call

China's foreign ministry said Saturday it has lodged a complaint with the United States over a controversial phone call between President-elect Donald Trump and Taiwan's President that has overturned decades of diplomatic protocol.

China views Taiwan as a renegade province and, since 1979, the US has acknowledged Beijing's claim that Taiwan is part of China, with US-China relations governed by a set of protocols known as the 'one China' policy.
