US President Barack Obama and Vietnamese General Secretary Nguyen Phu Trong shake hands during a meeting in the Oval Office of the White House in Washington, DC, July 7, 2015. President Barack Obama on Tuesday welcomed the leader of Vietnam’s Communist Party to the White House for a rare Oval Office meeting, two decades after the one-time enemies normalized relations. The talks with Trong — the first general secretary of the Vietnamese Communist Party to visit the United States and the White House — come as Washington looks to build deeper trade, military and political ties with Hanoi.
