A New Front in Asia’s Water War

For decades, China has been dragging its neighbors into high-stakes games of geopolitical poker over water-related issues. But the country's politically motivated decision to withhold hydrological data from India amounts to an escalation of China's efforts to exploit its status as the world's hydro-hegemon to gain strategic leverage over its neighbors.

NEW DELHI – China has long regarded freshwater as a strategic weapon – one that the country’s leaders have no compunction about wielding to advance their foreign-policy goals. After years of using its chokehold on almost every major transnational river system in Asia to manipulate water flows themselves, China is now withholding data on upstream flows to put pressure on downstream countries, particularly India.

For decades, China has been dragging its neighbors into high-stakes games of geopolitical poker over water-related issues. Thanks to its forcible annexation of Tibet and other non-Han Chinese ethnic homelands – territories that comprise some 60% of its landmass – China is the world’s unrivaled hydro-hegemon. It is the source of cross-border riparian flows to more countries than any other state.

In recent years, China has worked hard to exploit that status to increase its leverage over its neighbors, relentlessly building upstream dams on international rivers. China is now home to more dams than the rest of the world combined, and the construction continues, leaving downstream neighbors – especially the vulnerable lower Mekong basin states, Nepal, and Kazakhstan – essentially at China’s mercy.

Chris Patten

Hong Kong is a shining example of what Chinese men and women can achieve with the freedom that millions of others take for granted. Only if Hong Kong’s people are resolute in defending their freedom against Chinese government pressure can they hope to secure the "one country, two systems" they were promised.

    Richard N. Haass

    We are entering a new and dangerous period in which nuclear competition or even use of nuclear weapons could again become the greatest threat to global stability. Less certain is whether today’s leaders are up to meeting this emerging challenge.
