China’s $167 Billion Mega-Dam in Tibet Sparks Global Tensions and Environmental Fears

China has begun construction on what will be the world’s largest hydropower dam, a $167 billion project on the Yarlung Tsangpo River in Tibet.

The dam is expected to dwarf the Three Gorges Dam in both size and electricity output, generating up to 300 billion kilowatt-hours annually. While China touts the project as a major step toward renewable energy and economic stimulus, neighboring countries India and Bangladesh have raised serious concerns about water security, environmental impact, and regional stability, as the river flows downstream into their territories. The project has also triggered a surge in hydropower and construction-related stocks, but critics warn of potential ecological damage and lack of transparency in consultation and compensation.

The dam’s construction marks a new chapter in regional geopolitics, with water resources at the heart of growing tensions between China and its neighbors.
