WASHINGTON (AP) — U.S. President Donald Trump is hosting Chinese leader Xi Jinping in Washington this week as economic and tech competition escalates between the two countries. Both leaders are aiming to stabilize fragile ties, though no major agreements are expected. The meeting itself is seen as significant given the deep differences and a lack of trust between the United States and China. An accelerating artificial intelligence race is a key issue, with both countries vying for dominance despite warnings about the rapid development of the technology. Along with persistent trade issues, the two leaders also are trying to maneuver around major hot spots like Iran and Taiwan.
