US President Donald Trump met with Chinese leader Xi Jinping, a chance for the leaders of the world’s two largest economies to stabilize relations after months of turbulence over trade issues. 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 new urgency. There is a mutual recognition that neither side wants to risk blowing up the world economy in ways that could jeopardize their country’s fortunes. When the two sat down, Xi read prepared remarks that emphasized a willingness to work together despite their differences.
