President Trump arrived Monday in Japan, where new Prime Minister Sanae Takaichi is banking on building a friendly personal relationship with the U.S. leader to ease trade tensions.

Critical talks between US President Donald Trump and Chinese leader Xi Jinping have concluded in Busan, South Korea, where they discussed trade between the world’s two largest economies.

The trade war exploded this month after Beijing proposed dramatically expanding curbs on exports of rare-earth minerals vital for high-tech applications, a sector China dominates.

How Trump and Xi are reacting: “It was an amazing meeting,” the US president told reporters aboard Air Force One as he flew back to Washington on Thursday. “On a scale of 0-10, with 10 being the best, the meeting was a 12.” Trump said he will visit China in April and that Xi would make a reciprocal visit to the US.

U.S. President Donald Trump will visit China next year, a Chinese foreign ministry spokesperson said on Thursday following talks between Trump and President Xi Jinping in South Korea.

U.S. Trade Representative Jamieson Greer, also on the flight, said China would not be imposing its proposed rare earth controls after an understanding between the presidents.
