The threat posed by North Korea was a key topic in phone calls between U.S. President Donald Trump and the leaders of China and Japan, along with trade issues, the White House said on Sunday.

Trump spoke with Chinese President Xi Jinping and Japanese Prime Minister Shinzo Abe ahead of expected meetings with the leaders of Asia's two biggest economies at a Group of 20 nations summit in Germany later this week.
