President Donald Trump and Chinese leader Xi Jinping are meeting face-to-face today in South Korea. Tensions between the world's two largest economies have soared since Trump returned to office for a second term, and hiked import tariffs. China has retaliated by limiting exports of rare earth minerals, and shunning U.S. soybeans. The markets have been nervous but ahead of the meeting, officials from both countries signaled that there could be a detente. But the countries remain on a potential collision course as they compete to dominate manufacturing, develop AI technologies, and shape global affairs.
