Beijing, Dec 26: China has approved the construction of the world's largest dam, stated to be the planet's biggest infra project costing USD 137 billion, on the Brahmaputra River in Tibet close to the Indian border, raising concerns in riparian states - India and Bangladesh.

The Chinese government has approved the construction of a hydropower project in the lower reaches of the Yarlung Zangbo River, the Tibetan name for the Brahmaputra, according to an official statement quoted by state-run Xinhua news agency on Wednesday.

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 (USD 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 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, the size and scale of it could also enable Beijing to release large amounts of water flooding border areas in times of hostilities.

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 river and Sutlej river during the flood seasons.

Data sharing of trans-border rivers figured in the talks between India, China Special Representatives (SRs) for border question, 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.

The official statement on Wednesday sought to allay concerns about earthquakes, saying that the hydropower project is safe and prioritises ecological protection.

Through extensive geological explorations and technical advancements, a solid foundation has been laid for the science-based, secure, and high-quality development of the project, it said.

The Brahmaputra flows across the Tibetan Plateau, carving out the deepest canyon on Earth and covering a staggering vertical difference of 25,154 feet before reaching India, the Post report said.

The dam will be built in one of the rainiest parts of mainland China bringing bountiful flows of water.

According to a 2023 report, the hydropower station is expected to generate more than 300 billion kWh of electricity each year – enough to meet the annual needs of over 300 million people.

In 2020, Yan Zhiyong, then chairman of the state-owned Power Construction Corporation of China, was quoted in the media as saying the location on the Yarlung Tsangpo was one of the most hydropower-rich areas in the world.

“The lower reaches area features a vertical drop of 2,000 metres over a 50km distance, representing nearly 70 million kilowatts of resources that could be developed – that is more than three Three Gorges Dams with an installed capacity of 22.5 million kilowatts,” the Post quoted him as saying.

To harness the hydropower potential of the river, four to six 20km-long tunnels must be drilled through the Namcha Barwa mountain to divert half of the river’s flow at about 2,000 cubic metres per second, according to the report.

Yan said that the hydropower exploitation of the Yarlung Zangbo River downstream is more than a hydropower project.

It is also meaningful for the environment, national security, living standards, energy and international cooperation.

"It is a project for national security, including water resources and domestic security," he said, noting that the project will also smooth cooperation with South Asia.

The hydropower station could generate income of 20 billion yuan (USD three billion) annually for the Tibet Autonomous Region, he said.

An official statement on Wednesday defended the project, saying it will play a positive role in accelerating the country's efforts to create a new development pattern and pursue high-quality development.

It is also of great importance to advancing the country's strategy for carbon peaking and carbon neutrality and to coping with global climate change, it said.

The hydropower project is a green project aimed at promoting low-carbon development. By harnessing the abundant hydropower resources of the Yarlung Zangbo River, the project will also spur the development of solar and wind energy resources in surrounding areas, thus creating a clean energy base featuring a complementary mix of hydro, wind and solar power, it said.

It will directly stimulate the rapid growth of such industries as engineering, logistics and trade services, and create new jobs, it said.

Once completed, the project will further improve infrastructures of electricity, water conservancy and transportation. It will strengthen the synergy of development between Tibet and other regions, it said.

New Delh (PTI) The Congress on Saturday said it is perhaps not very surprising that India is not part of a US-led strategic initiative to build a secure silicon supply chain, given the "sharp downturn" in the Trump-Modi ties, and asserted that it would have been to "our advantage if we had been part of this group".

Congress general secretary in charge of communications Jairam Ramesh took a swipe at Prime Minister Narendra Modi, saying the news of India not being part of the group comes after the PM had enthusiastically posted on social media about a telephone call with his "once-upon-a-time good friend and a recipient of many hugs in Ahmedabad, Houston, and Washington DC".

In a lengthy post on X, Ramesh said, "According to some news reports, the US has excluded India from a nine-nation initiative it has launched to reduce Chinese control on high-tech supply chains. The agreement is called Pax Silica, clearly as a counter to Pax Sinica. The nations included (for the moment at least) are the US, Japan, the Republic of Korea, Singapore, the Netherlands, the United Kingdom, Israel, the United Arab Emirates, and Australia."

"Given the sharp downturn in the Trump-Modi ties since May 10th, 2025, it is perhaps not very surprising that India has not been included. Undoubtedly, it would have been to our advantage if we had been part of this group."

"This news comes a day after the PM had enthusiastically posted on his telephone call with his once-upon-a-time good friend and a recipient of many hugs in Ahmedabad, Houston, and Washington DC," the Congress leader asserted.

The new US-led strategic initiative, rooted in deep cooperation with trusted allies, has been launched to build a secure and innovation-driven silicon supply chain.

According to the US State Department, the initiative called 'Pax Silica' aims to reduce coercive dependencies, protect the materials and capabilities foundational to artificial intelligence (AI), and ensure aligned nations can develop and deploy transformative technologies at scale.

The initiative includes Japan, South Korea, Singapore, the Netherlands, the United Kingdom, Israel, the United Arab Emirates, and Australia. With the exception of India, all other QUAD countries -- Japan, Australia and the US -- are part of the new initiative.

New Delhi will host the India-AI Impact Summit 2026 on February 19-20, focusing on the principles of 'People, Planet, and Progress'. The summit, announced by Prime Minister Narendra Modi at the France AI Action Summit, will be the first-ever global AI summit hosted in the Global South.

Prime Minister Modi and US President Trump on Thursday discussed ways to sustain momentum in the bilateral economic partnership in a phone conversation amid signs of the two sides inching closer to firming up a much-awaited trade deal.

The phone call between the two leaders came on a day Indian and American negotiators concluded two-day talks on the proposed bilateral trade agreement that is expected to provide relief to India from the Trump administration's whopping 50 per cent tariffs on Indian goods.

In a social media post, Modi had described the conversation as "warm and engaging".

"We reviewed the progress in our bilateral relations and discussed regional and international developments. India and the US will continue to work together for global peace, stability and prosperity," Modi had said without making any reference to trade ties.
