**Deck**: China is building a $167 billion mega‑dam in Tibet that could generate three times the power of the Three Gorges Dam, raising concerns in India about how upstream control might affect shared rivers and water security.

China is pushing ahead with a $167 billion mega‑dam project in Tibet that, if completed as described, would generate three times the power of the Three Gorges Dam and intensify long‑running worries in India about control over shared rivers.

The project sits on the Tibetan Plateau, upstream from South Asian countries that depend on major rivers rising in territory under Chinese control. With a planned output several times larger than one of the world’s most famous dams, it would add a vast new source of hydropower to China’s grid.

For Beijing, the appeal of such a dam is clear: large amounts of electricity from a domestic, non‑fossil source and another anchor for economic activity in a remote border region.

For India, the scale and location of the project translate into questions about water security. When a river is first captured behind a massive dam upstream, downstream states inevitably worry about how that structure might be used in future disputes, even if formal river‑sharing arrangements or operating rules are in place.

Those concerns touch more than high politics. In practical terms, they’re about whether flows that support agriculture, cities and industry in India could be affected by how and when China stores or releases water through its turbines.

The dam also becomes another point of friction in a relationship already strained by border clashes and regional rivalry. Control over headwaters is part of that wider contest.

Signals that would ease or deepen concern include any public technical details China releases about the dam’s design and operation, offers of data sharing on river flows, and how India chooses to respond in its own water and dam‑building policies downstream.
