HANOI, Vietnam -- The Obama administration announced Monday that the United States would fully lift a longstanding U.S. embargo on lethal arms sales to Vietnam, a decision that reflects growing concerns about China's military clout and illustrates the warming bilateral ties between the former enemy nations.
President Obama unveiled the new arrangement at a news conference with Vietnamese President Tran Dai Quang during the opening day of his first visit to the country. Obama emphasized that his decision reflected a maturing relationship and deepening cooperation on security and economic investment four decades after the end of the Vietnam War."
