What do we know about the site of China’s mega dam in Tibet and what is its significance?

China has officially broken ground on what is set to become the world’s largest hydropower dam on the Tibetan Plateau.

The dam is being built on the Yarlung Tsangpo in Medog – a remote yet geopolitically significant county close to the disputed border with India.

As well as becoming a major energy source, the dam is a key element in Beijing’s plans to develop the region and strengthen its border security.

However, it could also aggravate tensions with India as a result of a long-running border dispute and concerns about the impact on the environment and water security.

What is the location?

Medog, also known as Motuo in Chinese, is a border county in the southeast of the Tibet autonomous region, which lies in the foothills of the Himalayas.
