The dam is to be built at a huge gorge in the Himalayan reaches where the Brahmaputra river makes a huge U-turn to flow into Arunachal Pradesh and then to Bangladesh. The total investment in the dam could exceed one trillion yuan ($137 billion), which would dwarf any other single infrastructure project on the planet including China’s own Three Gorges Dam, regarded as the largest in the world, the Hong Kong-based South China Morning Post reported on Thursday.
China has already Operationalised the $1.5 billion Zam Hydropower Station, the largest in Tibet in 2015.
