China has embarked on constructing the world’s largest hydroelectric dam on the Brahmaputra River (Yarlung Tsangpo in Tibet), and while the project promises massive energy generation, it simultaneously raises alarming strategic, environmental, and geopolitical concerns—especially for India and Bangladesh. The ability to block water during dry seasons or release it without warning during floods gives China an upper hand over downstream nations. Such control could have catastrophic consequences for millions of people, especially farmers in India’s Northeast and in Bangladesh who rely heavily on the river.
