China’s habitually closed water policy in the region of South-Еast Asia has strained its relations with the six countries of the Mekong-river basin. The Chinese government has been intentionally concealing its water management plans, which has sparked off a clash of interests between China and most SEA nations. The “dams policy” pursued by China enabled the country to take the Mekong run-off under control. At the same time, it has greatly affected the country’s international image, making China look like a regional bully.
