India fears a planned Chinese mega-dam in Tibet will reduce water flows on a major river by up to 85 per cent during the dry season, according to four sources familiar with the matter and a government analysis seen by Reuters, prompting Delhi to fast-track plans for its own dam to mitigate the effects.

The Indian government has been considering projects since the early 2000s to control the flow of water from Tibet’s Angsi Glacier, which sustains more than 100 million people downstream in China, India and Bangladesh.
