Why Vietnam Edging Closer, but not too Close, to the US Ralph Jennings TAIPEI, TAIWAN - The United States sent its second aircraft carrier in as many years to Vietnam this week, shortly after toughening up its treatment of the Southeast Asian country's economic prowess over concerns about the bilateral trade imbalance. Vietnam went along with both moves, yet didn't play up either. Vietnam and the United States are growing closer, despite their bitter war 50 years ago, as both hope to check Beijing's expansion in the South China Sea, analysts say. However, Vietnam's communist political system and pursuit of a multicountry foreign policy rather than a purely pro-Western one are likely to stop Washington from getting too close. For their part, U.S. officials worry about Vietnam's U.S. trade surplus. "Washington's institutional bureaucracy surely sees Hanoi as a partner in pushing back against Beijing's South China Sea claims and militarization," said Sean King, vice president of the New York-based Park Strategies political consultancy, "but Vietnam's not an ally, nor a democracy, hence there are limits to this partnership." "My sense is Vietnam wants [the United States] as a regional counterweight to Beijing but doesn't want to be part of any wider U.S.-mainland Chinese containment strategy," King said. .
