Assam CM Himanta: No Immediate Concern Over China’s Brahmaputra Dam

Rapid Summary

• Assam CM Himanta Biswa Sarma expressed no immediate concern over China’s construction of teh world’s largest dam on the Brahmaputra River, citing the river’s multiple water sources from Bhutan, arunachal Pradesh, adn local rainwater.
• China officially began constructing a $167.8 billion megadam in Tibet on July 19, 2025. It is expected to be larger then the Three Gorges Dam.
• The project includes five cascade hydropower stations and aims to generate over 300 billion kWh annually – enough for over 300 million people.
• CM Sarma noted differing scientific views: reduced water flow might affect biodiversity but could also mitigate floods downstream.
• The site is near tectonic plate boundaries prone to earthquakes and situated at one of Earth’s rainiest locations.
• Concerns raised include potential impacts on lower riparian countries (india and Bangladesh), with possible strategic implications during conflicts as China could control or flood border areas.
• India has an ongoing dam project in Arunachal Pradesh and maintains dialog with China through mechanisms like Expert Level Mechanism (ELM).

Indian Opinion Analysis

China’s ambitious megadam project along the Brahmaputra raises important questions about its environmental impact and geopolitical ramifications for India. While Assam CM Himanta Biswa Sarma downplayed immediate fears due to local water contributions from Bhutan,Arunachal Pradesh,and rainfall,uncertainties persist about long-term effects on biodiversity upstream versus flood regulation downstream.

The project’s location in a seismically active zone further amplifies concerns about structural safety amid high-intensity rainfall conditions – factors that could influence water manageability for all riparian stakeholders including Bangladesh.

On strategic concerns, controlling Brahmaputra’s flow gives Beijing leverage during disputes; however, India’s own hydropower initiatives in Arunachal Pradesh may serve to balance capacities within its borders while maintaining existing diplomatic mechanisms like ELM for data sharing.

It will be crucial for New Delhi’s policymakers not only to rely on dialogues but proactively track developments using scientific modeling tools to prepare mitigation strategies ensuring protections for both ecological balance and national security interests.
