China's proposed mega hydropower dam on the Yarlung Zangbo River has raised significant concerns in India due to potential impacts on water security and downstream communities.

China on Friday (December 27, 2024) defended its plan to build the world’s largest dam on the Brahmaputra river in Tibet, saying the project will not “negatively affect” lower riparian states and that safety issues have been addressed through decades of studies.

China recently authorized the construction of the largest dam in the world, which is expected to cost about $137 billion, on the Brahmaputra River in Tibet, close to the Indian border. Concerns about the dam's possible effects on water flow and regional stability have been raised by other nations,

China has approved the construction of the world's largest dam, stated to be the planet’s biggest infra project costing $137 billion, on the Brahmaputra River in Tibet close to the Indian border, raising concerns in riparian states — India and Bangladesh.

China has approved the construction of the world’s largest hydropower dam on the lower reaches of the Yarlung Zangbo River, the Tibetan name for the Brahmaputra, near the Indian border. The $137 billion project, described as the world's biggest infrastructure undertaking, has raised concerns in downstream nations India and Bangladesh.

The construction of dam over the Brahmaputra river will enable China to control the water flow. Notably, India is also constructing a dam over the Brahmaputra river in Arunachal Pradesh.

The $137 billion project, while promising clean energy and regional development, risks ecological damage, geopolitical tensions and water disruptions for downstream India and Bangladesh
