Beijing warned on Monday that its ties with the United States would be jeopardised if Washington did not stick to its stance that Taiwan is part of China.
Those who seek to damage the “one China” principle and harm China’s core interests are “lifting a rock only to drop it on their feet”, Chinese Foreign Minister Wang Yi said in comments carried on the Foreign Ministry’s website.
Speaking separately, ministry spokesman Geng Shuang said China was “extremely concerned” about Trump’s comments that Washington did not necessarily have to stick to the one-China policy.
The remarks signalled that Beijing was seriously dismayed by US president-elect Donald Trump’s moves and rhetoric on Taiwan, observers said.
