This Inquiry podcast episode investigates why China is building the world's largest dam. The interview-based format features experts discussing the dam's massive scale (three times larger than the Three Gorges Dam), remote location in Tibet, and potential for 60 gigawatts of hydropower. Concerns raised include the dam's environmental impact on the Yarlung Tsangpo River, resettlement of Tibetan communities, and potential for water disputes with downstream countries like India and Bangladesh, who fear water diversion or flooding. The discussion also touches upon China's broader energy and climate goals, comparing the situation to other international water disputes involving dams.
