The origins of the Mekong Committee are linked to the legacy of (de)colonialism in Indochina and subsequent geopolitical developments. The political, social, and economic conditions of the Mekong River basin countries evolved dramatically since the 1950s, when the Mekong represented the "only large river left in the world, besides the Amazon, which remained virtually unexploited." The impetus for the creation of the Mekong cooperative regime progressed in tandem with the drive for the development of the lower Mekong, following the 1954 Geneva Conference which granted Cambodia, Laos, and Vietnam independence from France. A 1957 United Nations Economic Commission for Asia and the Far East (ECAFE) report, "Development of Water Resources in the Lower Mekong Basin", recommended development to the tune of 90,000 km2 of irrigation and 13.7 gigawatts (GW) from five dams. Based largely on the recommendations of ECAFE, the "Committee for Coordination on the Lower Mekong Basin" (known as the Mekong Committee) was established in September 1957 with the adoption of the "Statute for the Committee for Coordination of Investigations into the Lower Mekong Basin". ECAFE's Bureau of Flood Control had prioritized the Mekong—of the 18 international waterways within its jurisdiction—in the hopes of creating a precedent for cooperation elsewhere. and "one of the UN's earliest spin-offs", as the organization functioned under the aegis of the UN, with its Executive Agent (EA) chosen from the career staff of the United Nations Development Programme (UNDP).
