China begins construction of planet's largest hydroelectric dam

### Construction Begins on World’s Largest Hydropower Dam

China has started building what officials describe as the largest hydropower dam in the world, located on the Yarlung Tsangpo River in Tibet.

Premier Li Qiang announced the project during a ceremony on Saturday, marking the beginning of construction. The news contributed to a rise in Chinese markets as expectations grew for the long-planned initiative, initially proposed in 2020 as part of the country’s 14th five-year plan.

The project has faced objections from India and Bangladesh, where the river flows, as well as Tibetan groups and environmental advocates.

According to state media, the dam will be constructed on the lower section of the river. Reports indicate it will include five hydropower stations, generating approximately 300 billion kilowatt-hours of electricity each year at an estimated cost of 1.2 trillion yuan (£124 billion).

By comparison, the Three Gorges Dam—previously the largest—cost 254.2 billion yuan and produces 88.2 billion kilowatt-hours annually.

Although no specific timeline or full scope of construction was provided, the reported figures exceed previous estimates from 2020.

China, which leads the world in carbon emissions, is rapidly expanding renewable energy projects as part of efforts to reduce emissions and ensure stable power supply. It operates tens of thousands of hydropower developments, far surpassing any other nation.

The Yarlung Tsangpo dam will reportedly utilize the river’s steep descent—dropping 2 kilometers over a 50-kilometer stretch as it curves through a canyon.

India and Bangladesh have expressed concerns that water flow could be restricted or redirected. The river, known as the Brahmaputra in India and Jamuna in Bangladesh, supports millions downstream.

Analysts have warned that the project could be leveraged as a strategic tool. In December, India formally raised concerns with China, which denied pursuing water dominance, stating it seeks cooperation with neighboring countries.

Tibetan groups have also voiced worries about sacred sites along the river and potential displacement of communities. Previous hydropower projects in the region have led to protests and arrests, according to activists.
