China Begins Construction on World's Largest Dam in Tibet Amid India Tensions
China has launched construction of the massive Medog hydroelectric dam in Tibet, sparking fierce geopolitical tensions with India over shared water resources and security concerns.
China announced the construction of the massive Medog hydroelectric dam in Tibet, sparking geopolitical tensions with neighboring India over shared water resources.
The Engineering Giant
On July 19, 2025, Chinese Premier Li Qiang announced the start of construction on the Medog hydroelectric plant in Tibet, which is slated to become the largest in the world. The project is expected to take about a decade and cost roughly 1.2 trillion yuan (around $167 billion), dwarfing the Three Gorges Dam.
The official reason behind the dam is clean energy demand. According to the Center for New Age Warfare Studies in India, the river's potential plays a major role in Beijing's transition plans aimed at achieving carbon neutrality by 2060.
Challenges and Concerns
Experts warn that the region is geologically unstable, prone to earthquakes and landslides, and the immense weight of the water could exacerbate these risks. Furthermore, human rights and environmental concerns mirror those raised during the Three Gorges Dam project, with fears of local displacement and the destruction of ancient monasteries.
"This is a ticking water bomb," stated Pema Khandu, Chief Minister of Arunachal Pradesh, reflecting India's deep anxieties over Beijing's control of the downstream flow.
Geopolitical Friction
India is highly dissatisfied with China's unilateral plans to control the river flow reaching its territory. China stopped sharing hydrological data with India in 2023, escalating tensions. In response, India announced plans to accelerate the construction of the Upper Siang dam, turning transboundary water management into a high-stakes geopolitical bargaining chip.
