The United States President, Donald Trump, and his Russian counterpart, Vladimir Putin, shook hands on the sidelines of Asia-Pacific Economic Cooperation (APEC) Summit in Vietnam on Friday. Trump and Putin, both of whom were dressed in oversized, blue traditional-style Vietnamese shirts provided by the host country, smiled and stood next to each other for the traditional group photograph. The White House said earlier that no formal meeting was planned because of scheduling conflicts on both sides, though there are possibilities that they might bump into each other. The main meeting of leaders from APEC countries is on Saturday in the Vietnamese resort city of Danang. Trump is on the fourth leg of a 12-day tour of Asia.
