Mekong River Economy
Much of this development work has been undertaken under the auspices of the Interim Committee for Coordination of Investigations of the Lower Mekong Basin (Mekong Committee), organized in 1957 by Cambodia, Laos, Thailand, and South Vietnam. (After 1975 Vietnam replaced South Vietnam on the committee, and Cambodia ceased to participate, although Cambodia has resumed membership since 1991.) The committee has sponsored a series of preinvestment and general scientific investigations and has undertaken construction of a number of water projects. These projects include the multipurpose dam near Nam Phong in northeastern Thailand and the hydroelectric dam at Nam Ngum in Laos. The countries of the commission have continued to cooperate despite the political stresses produced by the war in Vietnam and its aftermath and have enlisted the assistance of other countries and international organizations.
