China has commenced the construction of the Motuo Hydropower Station, poised to become the largest hydropower dam globally, situated in the Yarlung Tsangpo canyon—often dubbed the deepest land canyon. Through this extensive project, Chinese officials assert their commitment to ecological safeguarding and local economic enhancement. However, the initiative has sparked significant concern among neighboring countries, particularly India and Bangladesh, fearing severe ramifications for millions living downstream.

At the construction launch in Tibet, which sits atop this vital waterway, Premier Li Qiang underscored the initiative's potential benefits but downplayed criticisms concerning its possible disruptive impact on trans-border waterways. Experts noted that the dam could enable China to exert control over the Yarlung Tsangpo River, with potential threats to the water supply for Indian states Arunachal Pradesh and Assam, along with the broader ecosystem and human settlements that depend on these water resources.

Arunachal Pradesh's Chief Minister, Pema Khandu, voiced fears that the new dam might jeopardize the livelihood and existence of indigenous tribes in the region, underscoring the urgency and gravity of the project’s implications. In parallel, India's government has previously articulated concerns regarding such mega-dams, urging China to prioritize transparency and consult with lower riparian nations about water management.

The dam's construction raises alarm bells regarding sustainability, particularly given the ecological significance of the Tibetan Plateau and its inherent biodiversity. Additionally, it risks exacerbating an ongoing history of tensions in the region, as Tibetan protests against similar projects have often met with repression.

Chinese state media have framed these dams as environmentally friendly solutions to meet the energy demands of their industrialized eastern regions, yet many activists argue that these projects come at the cost of exploiting Tibetan communities and their rich cultural landscapes. Past incidents of crackdown against protesting Tibetans signal a concerning trend, raising critical questions about autonomy and environmental stewardship as China advances its infrastructure ambitions in the region.
