China's UN Ambassador Fu Cong wrote to UN Secretary-General Antonio Guterres last Friday that Japanese Prime Minister Fumio Kishida had committed a 'flagrant violation of international law and diplomatic norms' by saying any attack on Taiwan might prompt a military response from Tokyo. In the letter, according to a statement from China's UN mission, Fu added: 'If Japan dares to attempt to intervene... China will defend itself by all necessary means.' China has escalated its dispute with Japan to the United Nations, accusing Tokyo of threatening 'armed intervention' in the Taiwan issue and vowing to defend itself, using the strongest language yet since the crisis began two weeks ago.
