The Brahmaputra also known as the Yarlung Tsangpo river is one of the biggest rivers in Asia, and has strategic importance given that it flows across three international borders.

Now China has operationalised the biggest dam in Tibet built over Brahmaputra, at the cost of Rs 9700 crore, as reported by NDTV . The dam is a positive step towards development in Tibet, but is also a cause of concern for India in terms of security.

Here's all there is to know about the dam which is causing ripples across the subcontinent.

What it means for China

The dam, also known as the Zangmu Hydro-power Station, is built by hydro-power contractor China Gezhouba Group, based in central China's Hubei province, and is the biggest dam in Tibet.

The dam is also the world's highest altitude hydro-power station, which will produce 2.5 billion kilowatt-hours of electricity annually.

As per the company's claim, the dam will solve the power shortage in central Tibet and will provide a thrust to development.

As the electricity supply during summers is regularly available in the area, the power will be supplied to the neighbouring Qinghai province.

India's concerns

Three major dams including Jiexu and Jiacha other than the Zangmu power station are built on the river within 25 kms of each other and just 550 kms from the Indian border.

Indian authorities are worried as these dams can enable China to control the flow of water in the Brahmaputra.

The Indian administration is also concerned because of the possibility that China might release water to cause flooding in India, during any confrontation.

There is also skepticism regarding the water being diverted, having an effect on projects in Brahmaputra in Arunachal Pradesh.

Although China has assured that the dams it is building are just "run-of-the-river" projects, which are not designed to hold water, the Indian side is concerned about availability of water in the lower areas being restricted.
