Water Diplomacy through Dams (India-China)

📌 Background & Key Features

• Riparian asymmetry: India is a lower riparian state for the Brahmaputra with no binding water-sharing treaty with China (unlike the Indus Waters Treaty with Pakistan) — only an expert-level mechanism (since 2006) for hydrological data sharing.
• India’s fears: Possible flow manipulation (Reuters: up to 85% dry-season flow reduction feared), flash-flood risk from sudden releases, and strategic leverage over India in a crisis — dams as a potential "water weapon".
• Seismic risk: The project sits in a highly active Himalayan seismic zone, raising shared ecological concerns for India and Bangladesh (also a lower riparian).
• India’s counter-strategy is to build its own upstream storage/regulation capacity (Siang Dam) to buffer against sudden Chinese releases — turning water diplomacy into a race for infrastructure primacy.

📰 Current Affairs Linkage (2025-26)

• China formally approved the Yarlung Tsangpo Lower Reaches Hydropower Project in Dec 2024/2025 despite Indian and Bangladeshi objections; Beijing insists there will be no adverse downstream impact.
• India’s $77 billion Northeast hydropower transmission plan (Oct 2025) covering 208 dams is being read as a direct strategic response, while facing local opposition in Arunachal Pradesh over displacement and ecology.
• Bilateral talks in Beijing (March 2025) touched on water-data sharing as part of the broader post-Galwan normalisation package.
