Donald Trump has backed down over his confrontational stance towards Beijing, committing to the ‘One China policy’ in his first phone call with Xi Jinping, the Chinese president, since taking office.

In a move that is certain to ease tensions between the United States and China, the US president “agreed, at the request of President Xi, to honour our ‘one China’ policy,” the White House said in a statement.

The “lengthy telephone conversation” on Thursday evening was “extremely cordial” and the two leaders “extended invitations to meet in their respective countries,” the statement added.

Mr Xi told Mr Trump that he appreciated the president's reaffirmation of the policy, China's state news agency Xinhua reported.

Mr Trump angered Beijing by accepting a congratulatory call from the President of Taiwan in December, breaking decades of diplomatic protocol.

He has since suggested there could be a renegotiation of the One China policy, in which the US recognises there is one China and Taiwan is part of that. Beijing views Taiwan as a breakaway province, which will be reunited with the mainland, by force if necessary.
