China keeps the Yarlung Zangbo mega-dam in the 15th Five-Year Plan after the Nepal flood

China's 15th Five-Year Plan for renewable energy, issued on 23 July 2026, still lists the Yarlung Zangbo Lower Reaches Hydropower Project among the schemes to push forward. The Hindu's Beijing correspondent, writing after the 26 August glacial collapse on the Nepal-China border, said that disaster is unlikely to take the dam off the plan. The river becomes the Brahmaputra in Arunachal Pradesh and then Bangladesh.

Premier Li Qiang opened the ground in Nyingchi in July 2025 and called it the project of the century. The announced investment is 1.2 trillion yuan, about Rs 14 lakh crore, for five power stations. Chinese briefings put annual output near 300 billion kilowatt-hours, roughly three times the Three Gorges station. WION's explainer placed the cost near $68 billion and the site at the Great Bend, where the river drops through the world's deepest canyon before it enters India.

The location is the problem as much as the scale. The bend sits in a seismic belt a short distance from a militarised stretch of the Line of Actual Control. A paper in the Chinese journal Sedimentary Geology and Tethyan Geology, cited by Brahma Chellaney and by South China Morning Post earlier this year, said an active fault, named in some accounts as the Paishan fault, runs under or beside the works and could affect structural stability. When a state-linked journal prints that sentence, downstream governments treat it as an admission, not a rumour.

India's concern is water and silt, not only electricity. A dam that high can hold a flood pulse or release one. After a glacial collapse has already killed more than 1,300 people in Nepal and left thousands missing, the argument that Himalayan slopes are stable enough for a reservoir of this size is harder to make in public. Bangladesh, which takes the river in its last, flat reach, has the same exposure and less military leverage.

Beijing's reply has been consistent for two years. The project is domestic, on Chinese territory, and part of the energy transition. It does not, in that telling, require an Indian or Bangladeshi veto. There is no basin treaty on the Brahmaputra that would force a joint design review. Hydrological data sharing has been patchy in past flood seasons.

What the July plan adds is bureaucratic momentum. A Five-Year Plan line item tells provinces and central energy firms to keep spending. It is not a construction log. Tunnels, cofferdams and the first concrete lifts will show whether the July 2025 ceremony became a working site or a ribbon on a hillside. The geology paper is the document to set against those lifts.

New Delhi's tools are diplomatic protest, satellite watch and the eastern-sector military talks that opened at Wacha on Sunday. None of those tools stops a pour of concrete. They do decide how loudly India describes the dam as a flood risk the next time the Brahmaputra runs high at Dibrugarh.
