The president has spoken with the leaders of both countries as they spar over remarks the Japanese prime minister made about the Beijing-claimed island democracy.

President Donald Trump had a phone conversation with Japanese Prime Minister Sanae Takaichi shortly after speaking with Chinese President Xi Jinping.
