Aides to Trump and Xi have discussed a potential meeting between the leaders during a trip by the U.S. president to Asia later this year, sources previously told Reuters. A trip would be the first face-to-face encounter between the men since Trump's second term in office, at a time when trade and security tensions between the two superpower rivals remain elevated. While plans for a meeting have not been finalized, discussions on both sides of the Pacific have included a possible Trump stopover around the time of the Asia-Pacific Economic Cooperation summit in South Korea or talks on the sidelines of the October 30-November 1 event, the people said.
