The Mekong Committee, which was composed of the four riparian countries in the lower Mekong river basin, was created in 1957 for the purpose of promoting economic development of the river basin. The Committee in 1970 elaborated the Indicative Basin Plan (IBP), which aimed at flood control, irrigation and power generation within riparian countries, by constructing several large dams in the mainstream. Integrated management of the basin was then assumed essential to promote such a huge development scheme.
However, the scheme suggested in IBP was not materialized, due to (i) lack of support from the World Bank and associated financing organizations, and (ii) changeover of political regime in Cambodia, Laos and Vietnam in mid 1970's. The circumstance remained unchanged until early 1990's.
The new agreement among basin countries was adopted in 1995. Though it provides principles for sustainable development, utilization, management and conservation of the water and related resources of the Mekong river basin, the integrated management of the river basin is now much less likely to be materialized (than it used to be in early 1970's) due to following factors: (i) Thailand puts the highest priority on securing water resources from the Mekong river for her irrigation development scheme in the north-eastern region, to which Vietnam has objected. (ii) Cooperation among riparian countries is now less firm, than it used to be in 1960's, due to the conflict between Thailand and Vietnam. (iii) Thailand, as a rapidly industrializing country, does not need to stay within the framework of cooperation among basin countries, which used to be a show-case to solicit funds from developed countries and aid organizations, and (iv) large-scale development projects in the main stream, as suggested in IBP, may no longer be implemented due to their possible effects on environment.
