New Delhi, India – In a significant move to bolster its strategic security and counter potential downstream impacts from China’s ambitious hydropower project on the Yarlung Tsangpo river, India has initiated work on the Dibang Multipurpose Project in Arunachal Pradesh. This project will feature what is set to be India’s highest dam upon completion.

- Objective: The primary aim of the Dibang Dam is to serve as a crucial buffer against any sudden or uncontrolled water releases from China’s mega-dam on the trans-border river. This initiative is designed to prevent potential flooding in downstream Indian territories.
- Dam Specifications: The Dibang Dam is expected to be India’s highest dam.
- Project Timeline: As per the tender, the project has a 91-month deadline, with completion anticipated by 2032.
- Investment: The Indian government, through the state-run NHPC Limited, has launched a global bid valued at ₹17,069 crore for the construction of the main dam.
- Strategic Importance: The dam is deemed critical for India’s strategic security, particularly in light of China’s ongoing infrastructure development on the Tibetan Plateau.
The Yarlung Tsangpo River and China’s Mega Project
The Yarlung Tsangpo river, which flows into India as the Brahmaputra, is a vital trans-boundary river system. Reports indicate that China has commenced work on a significant hydropower project along this river in the Tibetan Plateau. This development has raised concerns in India regarding potential water security and flood management.
India’s Response: Building a Strategic Buffer
The Dibang Multipurpose Project is India’s proactive measure to mitigate any adverse effects stemming from China’s project. By constructing one of the highest dams in the country, India aims to:
- Regulate Water Flow: Create a substantial reservoir capacity to manage and regulate water flow from the upstream.
- Enhance Flood Control: Provide a critical defense mechanism against flash floods or sudden surges of water.
- Strengthen National Security: Ensure greater control over a vital water resource and enhance preparedness for potential water-related security challenges.
