China plans to build the dam at the “Great Bend,” where the river makes a dramatic U-turn before entering India’s Arunachal Pradesh. The location, marked by tectonic instability, amplifies concerns about potential environmental disasters.

Defence Minister Rajnath Singh on Tuesday (7 January) said that the government is on alert regarding China’s announcement to construct the world’s largest dam on the Brahmaputra River in Tibet, near the Indian border.

Trans-border rivers from China to India fall into two main groups—the Brahmaputra river system on the eastern side and the Indus river system on the western side.

The reaction from Rajnath Singh came days after China announced its plan to construct the world's largest dam on the Brahmaputra, and India said it will continue to monitor and take necessary measures to protect its interests.

China reiterated its stand on Tuesday to build dam project in upstream belt of Brahmaputra in its own territory, saying it will “help” downstream countries, including India and Bangladesh, with their “disaster prevention and reduction and climate response”.

China has reaffirmed its plans to construct the world's largest dam on the Brahmaputra River in Tibet, near the Indian border. Despite concerns from India and Bangladesh, China insists the dam will not harm downstream countries.

Concerns have been raised in India about the hydropower project enabling China to flood border areas during times of conflict.

China has reiterated its commitment to building the world’s largest dam on the Brahmaputra River, assuring India and Bangladesh that it will not negatively impact their water resources or the environment,
