Chinas Medog Dam Sparks Transboundary Geopolitical Conflict Concerns

While the exact location of the Motuo Hydropower Project is not known, it is set to be built in Medog County near Nyingchi just upstream of the Great Bend on this map meaning it would be only 100-200 km away from the border between Tibet and the disputed state of Arunachal Pradesh. Map Source: The World Bank with annotations added for clarity (purple and red) In response to the Motuo Hydropower Project, India threatened to build a dam on the Brahmaputra. “This happens a lot when you’ve got a transboundary river and one country builds a dam; it sort of spurs competition,” Tilt explained.

In February 2025, Bangladeshi officials formally requested more information from Beijing, citing potential impacts on river flow, agriculture, and livelihoods in the densely populated delta region, which depends heavily on consistent water levels from transboundary rivers originating in Tibet. China describes the Medog Hydropower Station as a run-of-the-river project with no impact on downstream flow, but Bangladesh has sought technical transparency and hydrological data to verify this. Malik Fida Khan, head of the Center for Environmental and Geographic Information Services, warned that disruptions to the Brahmaputra—source of 70 percent of dry-season flow in the Ganges-Brahmaputra-Meghna basin—could harm Bangladesh's water security.

By framing the new Medog county dam as a necessary investment to improve the livelihoods of Chinese nationals, local governments are generating legitimacy for large state infrastructure in Tibet and securing their position in delivering the same to the region. ... Beijing’s decision to build a mega-dam over the Yarlung Tsangpo in Tibet has in many ways raised concerns in New Delhi over its transboundary water security and potential ecological risks in Northeast India.

China’s unilateral decision to build the Medog dam, without consulting downstream nations, raises geopolitical tensions in South Asia. The lack of a water-sharing treaty between China, India, and Bangladesh further exacerbates the situation. While China has provided hydrological data to India since 2006 and to Bangladesh since 2008, experts argue that such data-sharing agreements are insufficient in preventing potential water conflicts. India has expressed concerns about China’s control over transboundary rivers, with policymakers advocating for stronger diplomatic and strategic countermeasures.

However, several factors make this project questionable both in terms of necessity and feasibility. 1. Seismic Risks: The region is highly prone to earthquakes due to its position on the Indian and Eurasian tectonic plates.

The Medog dam is central to China’s hydropower ambitions but raises critical issues: • Lack of Transparency: No public participation, Environmental Impact Assessment (EIA), or Free, Prior, Informed Consent (FPIC). • Forced Displacement: Local Tibetan communities face relocation without ...

The inability to make binding decisions ... and transboundary water governance. Long-term progress will require not only technical and infrastructural responses but also political will, constitutional clarity and strategic foresight to navigate the layered complexities of water security in ...

The study identified the same river where the Medog Hydropower Station will be constructed, the Brahmaputra River, as a potential source of disagreement between the two nuclear nations. More specifically, even the perception of upstream water manipulation during extreme climate events could strain regional relations. The report states that “China’s lack of transparency in its dam projects on transboundary rivers, and severe distrust between the two rivals, create additional risks of misperception and attendant security tensions.” Therefore, any major dam project such as the Medog Station has the potential to significantly impact Chinese/Indian affairs.

The construction of the Medog Dam in one of the world’s most seismically active regions significantly magnifies · transboundary human and environmental risks. Situated along a major geological fault intersecting the Yarlung · Tsangpo, the project exemplifies the dangers of large-scale hydropower development in tectonically unstable
