NEW DELHI -- China's move to build a $137 billion hydropower project in Tibet -- which will be the world's largest -- has triggered environmental and security concerns in India, at a time when frosty ties between the neighbors appear to be thawing.
The proposed dam in the lower reaches of the Yarlung Tsangpo river, known as Brahmaputra in India, is expected to generate 300 billion kilowatt-hours of electricity annually, about three times the power of China's Three Gorges Dam, currently the world's biggest.
