U.S. President Barack Obama had a mixed message Tuesday for Vietnam’s leaders. During his first visit to Vietnam, Obama spoke about the Vietnamese and American people beginning “on a 100-year journey together.” But he said Vietnam needs to do more to improve human rights. The president made the comments in a speech at Hanoi’s National Convention Center. Tuesday was the second day of Obama’s three-day trip to Vietnam. Earlier on his visit, he gave the Vietnamese government what it wanted an end to an almost 50-year-old ban on selling military equipment to Vietnam. “Just a generation ago, we were adversaries and now we are friends," he said. In his speech, Obama said that Vietnam is now among the top 10 countries sending students to American colleges and universities. He said a record 19,000 Vietnamese are studying in the United States this year. “And last year, Vietnam welcomed nearly half a million American tourists to this country, and I will assure you that more are on their way,” Obama said.
