China Pushes Ahead with Brahmaputra Mega‑Dam Despite Fresh Safety Worries

Beijing has reiterated its commitment to the massive hydropower scheme that will harness the lower reaches of the Yarlung Zangbo – known downstream as the Brahmaputra – even as fresh alarm bells rang after a catastrophic glacial collapse on the Nepal‑China frontier.

The project, which Chinese officials have dubbed the “project of the century,” is a cornerstone of the country’s 15th Five‑Year Plan for renewable energy. When the plan was unveiled on July 23, 2026, the Yarlung Zangbo Lower‑Reaches Hydropower Project was listed alongside other flagship schemes, signalling that it is far from a side‑note.

In April, Vice‑Premier Zhang Guoqing toured Nyingchi, the Tibetan prefecture bordering India, and urged officials to “shoulder the principal responsibility for project‑building” while emphasizing quality, safety and environmental safeguards. “Construction progress must be subordinate to quality and safety,” he told the media.

Construction actually began in July 2025, when Premier Li Qiang visited the site, cut the ribbon and called the dam a “landmark mega‑project of the new era.” The ambition is bold: the dam is expected to generate roughly three times the electricity of the Three Gorges dam, making it one of the world’s most powerful hydro facilities.

Yet the optimism is tempered by a string of concerns. The dam will sit in a seismically active zone, perched over a known fault line. Geologists in China have already flagged the risk of earthquakes, while downstream neighbours – especially India – warn that any failure could unleash floods across the Brahmaputra basin, jeopardising millions.

Adding urgency to these fears, a sudden glacial outburst on August 26, 2026 triggered flash floods and deadly mudslides along the Nepal‑China border. The disaster has sharpened India’s anxiety about the dam’s potential to aggravate downstream water flows, especially during monsoon season.

Environmental NGOs echo the apprehensions, pointing to the dam’s likely impact on river ecology, sediment transport and the livelihoods of communities that depend on the Brahmaputra’s waters. Yet Beijing’s stance remains unchanged: the project will move forward, with promised “strict enforcement of construction standards and ecological‑environmental‑protection requirements.”

As the water rushes through the rugged Tibetan canyon, the debate over the dam’s fate is unlikely to cool. What is clear, however, is that China sees the megaproject as essential to its renewable‑energy roadmap, while its neighbours watch with growing unease.
