China defended its plan to build the world’s largest dam on the Brahmaputra River in Tibet, saying the project will not “negatively affect” lower riparian states and that safety issues have been addressed through decades of studies. Chinese Foreign Ministry spokesperson Mao Ning played down apprehensions about the massive project to dam the Brahmaputra River, which is called Yarlung Zangbo in Tibet. The project estimated to cost around USD 137 billion is located in the ecologically fragile Himalayan region, along a tectonic plate boundary where earthquakes occur frequently.
Mao said China carried out in-depth studies for decades and took safeguard measures. China has always been responsible for the development of cross-border rivers, Mao told a media briefing here in response to a question on the concerns related to the dam. She said the hydropower development there has been studied in depth for decades, and safeguard measures have been taken to ensure the project’s security and ecological environment protection.
“The project will not negatively affect the lower reaches,” she said referring to the concerns in India and Bangladesh which are the lower riparian states. “China will continue to maintain communication with countries at the lower reaches through existing channels and step up cooperation on disaster prevention and relief for the benefit of the people by the river,” she said.
She said China’s hydropower development in the lower reaches of the Yarlung Zangbo River aims to speed up the development of clean energy and respond to climate change and extreme hydrological disasters. China on Wednesday approved the construction of the world’s largest dam, stated to be the planet’s biggest infra project on the Brahmaputra River in Tibet close to the Indian border, raising concerns in India and Bangladesh.
The hydropower project will be built in the lower reaches of the Yarlung Zangbo River, the Tibetan name for the Brahmaputra River, an official statement here said. The dam will 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.
Mao said China’s hydropower development in the lower reaches of the Yarlung Zangbo River aims to speed up the development of clean energy and respond to climate change and extreme hydrological disasters.
The total investment in the dam could exceed one trillion yuan (USD 137 billion), which would dwarf any other single infrastructure project on the planet, including China’s own Three Gorges Dam which is regarded as the largest in the world, the Hong Kong-based South China Morning Post reported on Thursday. China has already operationalised the USD 1.5 billion Zam Hydropower Station, the largest in Tibet in 2015.
The Brahmaputra dam was part of the 14th Five-Year Plan (2021-2025) and National Economic and Social Development and the Long-Range Objectives Through the Year 2035 adopted by Plenum, a key policy body of the ruling Communist Party of China (CPC) in 2020.
Concerns arose in India as the dam besides empowering China to control the water flow could enable Beijing to release large amounts of water flooding border areas in times of hostilities because of its size and scale. India too is building a dam over Brahmaputra in Arunachal Pradesh.
India and China established the Expert Level Mechanism (ELM) in 2006 to discuss various issues related to trans-border rivers under which China provides India with hydrological information on the Brahmaputra and Sutlej Rivers during the flood seasons.
Data sharing of trans-border rivers figured in the talks between India, China Special Representatives (SRs) for border questions which NSA Ajit Doval and Chinese Foreign Minister Wang Yi held here on December 18. The SRs provided positive directions for cross-border cooperation and exchanges including data sharing on trans-border rivers, a statement by the Ministry of External Affairs said.
The Brahmaputra Dam presents enormous engineering challenges as the project site is located along a tectonic plate boundary where earthquakes occur. The Tibetan plateau, regarded as the roof of the world, frequently experiences earthquakes as it is located over the tectonic plates.
