          China’s Hydro-Hegemony

          ASIA is the world’s most water-stressed continent, a situation compounded by China’s hydro-supremacy in the region. Beijing’s recent decision to build a slew of giant new dams on rivers flowing to other countries is thus set to roil riparian relations.

          China — which already boasts more large dams than the rest of the world put together and has unveiled a mammoth $635-billion fresh investment in water infrastructure over the next decade — has emerged as the key obstacle to building institutionalized collaboration on shared water resources in Asia.

          In contrast to the bilateral water treaties between many of its neighbors, China rejects the concept of a water-sharing arrangement or joint, rules-based management of common resources.
          For example, in rejecting the 1997 United Nations convention that lays down rules on shared water resources, Beijing asserted its claim that an upstream power has the right to assert absolute territorial sovereignty over the waters on its side of the international boundary — or the right to divert as much water as it wishes for its needs, irrespective of the effects on a downriver state.
          Today, by building megadams and reservoirs in its borderlands, China is working to re-engineer the flows of major rivers that are the lifeline of lower riparian states.

          China is the source of transboundary riverflows to the largest number of countries in the world — from Russia, Kazakhstan and Kyrgyzstan to the states in the Indochina peninsula and Southern Asia. This pre-eminence resulted from its absorption of the ethnic-minority homelands that now make up 60 percent of its landmass and are the origin of all the international rivers flowing out of Chinese-held territory. No other country in the world comes close to the hydro-hegemony that China has established.

          Since the last decade, China’s dam building has been moving from dam-saturated internal rivers to international rivers. Most of the new megaprojects designated recently by China’s state council as priority ventures are concentrated in the country’s seismically active southwest, which is largely populated.
