China has reiterated its plan to build the world's largest dam over the Brahmaputra River in Tibet, near the Indian border. The Chinese Foreign Ministry has assured that the project, estimated to cost around USD 137 billion, will not have any negative impact on downstream countries, India and Bangladesh. The ministry has stated that the project has undergone rigorous scientific verification and will be conducive to disaster prevention and mitigation, as well as climate change response. India has expressed concerns about the dam, raising the issue during talks with the visiting US National Security Advisor, Jake Sullivan. China has maintained that the project will not negatively affect the lower reaches and has committed to maintaining communication with downstream countries.
