Mekong River—The Lifeblood of Southeast Asia The Mekong River is the heart and soul of Southeast Asia.The 12th longest river in the world，the Mekong runs 4800 kilometers from Tibet through Yunnan Province in China，to Burma，Thailand，Cambodia，Laos and Vietnam. Over 60 million people depend on the Mekong for food，water，transport in their daily lives.Along the riverbank rice and vegetables grow well.As the Mother of waters，the river gives one of the world’s richest fishes，second to the Amazon(亚马逊河)． Over the past ten years，more than 100 large dams(大坝)have been built.One of the greatest threats is China’s plans to build eight dams on the Upper Mekong—Lancang.Two of these dams have already been completed.These dams will have widespread impacts (影响)on the livelihoods of Mekong communities and on the natural ecology(生态) of the river system. In Laos，people are working to stop World Bank support for the Dam and ensure that losses become smaller from the dams.In Thailand，they have been working with communities affected by the Pak Mun and Rasi Salai dams. The Yali Falls Dam in Vietnam has affected communities in both Vietnam and Cambodia.
