U.S. President Barack Obama (2nd R) shakes hands with Vietnam's Communist Party General Secretary Nguyen Phu Trong after they spoke to reporters following their meeting in the Oval Office at the White House in Washington July 7, 2015. Trong is Vietnam's first party general secretary to visit the U.S., as Hanoi has strengthened its military relationship with former foe Washington since a territorial dispute with Beijing in the South China Sea has heated up in the past couple of years.
