Rajnath Singh assures India's vigilance over China's Brahmaputra dam plans, emphasises dialogue to safeguard interests. Highlights need for open regional communication

Defence Minister Rajnath Singh said that the Indian government is “on high” alert following China’s announcement to construct the world’s largest dam on the Brahmaputra River in Tibet.

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.

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

Chinese officials say that hydropower projects in Tibet will not have a major impact on the environment or on downstream water supplies.

Estimated at a cost of approximately USD 137 billion, the dam is to be built in the ecologically fragile Himalayan region.

China reiterates its plan to build the world's biggest dam over the Brahmaputra River in Tibet. Says that the planned project near the Indian border has gone through rigorous scientific verification and that it will not have any negative impact on downstream countries.
