President Trump and Chinese leader Xi Jinping spoke on Thursday, and both countries pledged to restart tariff and trade talks in the coming days. Trump hailed the call as "positive," with both leaders inviting the other to visit their respective countries.

President Donald Trump says China and the U.S. have agreed to more tariff talks amid trade standoff and concerns over rare earths.

And Beijing complained that the U.S. violated the deal with further restrictions on access to artificial-intelligence chip technology and electronic design automation software. The State Department’s plans to revoke Chinese students’ visas, announced after the truce, added to China’s concern.
