"India-China Brahmaputra Dispute: Data Gaps and Medog Dam Stakes"
Yarlung Tsangpo
The Tibetan name for the Brahmaputra River before it enters India through Arunachal Pradesh.
Memorandum of Understanding (MoU)
A non-binding agreement between states; can be suspended without legal breach, unlike a treaty.
The Tibetan Plateau is often called the 'water tower of Asia.' It is the source of several of Asia's largest rivers, including the Yarlung Tsangpo (which enters India as the Brahmaputra through Arunachal Pradesh), the Sutlej, and the Indus. All three originate in territory controlled by China. This gives China a structural upstream advantage over India and other downstream nations.
India and China have no comprehensive water treaty. Their entire legal architecture for transboundary river management rests on two non-binding Memorandums of Understanding: one on the Brahmaputra signed in 2002 and one on the Sutlej signed in 2005. India pays approximately one crore rupees annually for hydrological data under these arrangements. A consultative Expert Level Mechanism was added in 2006, but it meets only when bilateral relations permit. Neither country has joined the 1997 UN Convention on the Law of the Non-Navigational Uses of International Watercourses, the primary international instrument that would require upstream states to give prior notice and avoid causing significant harm downstream. China voted against it; India abstained.
This pattern of refusing binding multilateral water obligations is not unique to the Brahmaputra. China is also the largest upstream state on the Mekong River, yet it is deliberately excluded from the Mekong-Ganga Cooperation initiative, a six-nation framework involving India, Myanmar, Thailand, Laos, Cambodia, and Vietnam, precisely because China has consistently declined binding multilateral water-sharing commitments on rivers it controls upstream. The same logic applies to the Brahmaputra: a non-binding memorandum can be suspended without legal breach, which is exactly what has happened during periods of bilateral tension.
The weakness of the current framework is structural, not incidental. A memorandum of understanding carries no enforcement mechanism. When bilateral relations deteriorate, data sharing stops. During the 2017 Doklam standoff, China suspended Brahmaputra flood-season data, citing damaged monitoring stations. That summer, floods killed scores of people in Assam. China resumed data sharing once relations improved, then stopped again after the 2020 Galwan clash. The Brahmaputra MoU lapsed in June 2025 without renewal, and India has been pressing for data restoration since.
China's position frames data sharing as a sovereign act, not an obligation. Its foreign ministry describes hydrological data as something shared voluntarily, within the limits of what sovereignty permits. This framing converts a humanitarian question, will you warn people downstream of a flood?, into a territorial one. The downstream state is left with no legal right to demand information and no independent means to verify what it is told, because Tibet is effectively closed to outside inspection. …
