As a saying goes, “shared river, shared future”. Lancang-Mekong countries face similar problems and challenges in the pursuit of environmental protection and sustainable development. The countries have all agreed to build a Lancang-Mekong community of shared future by seeking complementary advantages and mutual promotion between LancangMekong Cooperation (LMC) and other sub-regional mechanisms through cooperation in production capacity, innovation, people’s livelihood and environmental protection, with emphasis placed on building the Mekong-Lancang Economic Development Belt.

Improving the ecological environment, protecting and making reasonable use of water resources, and working together to implement the “Green Lancang-Mekong Initiative” is an important direction towards which the cooperation among Lancang-Mekong countries moves. Having come to the stage of rapid industrialization and urbanization, the countries are witnessing similar water environment pollution problems. Problems such as water pollution, drinking water security, and industrial and agricultural water stress, which are caused by domestic sewage and industrial wastewater as a result of population growth and industrial and agricultural development, are increasingly prominent, threatening environmental and human health.
