Trump's aggressive use of tariffs since returning to the White House for a second term combined with China's retaliatory limits on exports of rare earth elements have given the meeting newfound urgency. There is a mutual recognition that neither side wants to risk blowing up the world economy in ways that could jeopardize their own country's fortunes

The meeting lasted a little over 100 minutes, with the two leaders shaking hands and Trump appearing to say something into Xi's ear, just before the Chinese leader entered his own limousine. Trump was shortly back aboard Air Force One to return to Washington

Before the meeting, Trump was optimistic. "We're going to have a very successful meeting, I have no doubt," Trump said, adding that Xi is a "very tough negotiator." Trump said they "could" possibly sign a deal coming out of the meeting and that they have a "great understanding" of each other

When the two were seated, Xi read prepared remarks that stressed a willingness to work together despite differences

The leaders met in Busan, South Korea, a port city about 76 kilometers south from Gyeongju, the main venue for the Asia-Pacific Economic Cooperation summit
