Trump backs One China policy in 'cordial' call with Xi The White House says US President Donald Trump has agreed to honour the so-called "One China" policy in a phone call with Chinese President Xi Jinping. The One China policy is the diplomatic acknowledgement that there is only one Chinese government. Mr Trump had placed the long-standing policy in doubt when he spoke with Taiwan's President in December. China sees Taiwan as a breakaway province to be reunified with the mainland. The move was a major break from traditional protocol and provoked an official complaint from China. The telephone conversation was the first between the two since Mr Trump took office on 20th January, though the new US President has called several other national leaders. SOURCE: BBC NEWS
