Chinese Support Gives Laos an Edge Over Powerful Neighbor Vietnam Ralph Jennings TAIPEI, TAIWAN - A Mekong River hydropower dam scheduled to open this month worries Vietnam because the country sits just downriver from it and would be threatened by lower water flows. Officials in Hanoi aren't wildly protesting to the dam's host country, Laos, however, because Vietnam knows Laos has support from their much larger neighbor, China. Vietnamese leaders instead are approaching Laos cautiously about the dam, out of fear the tiny landlocked country would seek more of that help from Beijing, Southeast Asia scholars say. Vietnam struggles to get along with China and resents Chinese expansion in other parts of Asia. The new fear in Hanoi shows it can no longer treat Laos as a client state as it's used to doing, those experts say. "Vietnam is worried that Laos is just doing a little bit too much to dam up the Mekong," said Murray Hiebert, senior associate of the Southeast Asia Program at the think tank Center for Strategic and International Studies in Washington. "But Vietnam, although they have talked quietly to the Lao, it has not chosen the nuclear option to carry on very publicly and condemn Laos." .
