China’s hydro diplomacy: water security, regional tensions, and the quest for balance in Asia

In 2022, China utilized a large-scale water transfer system to meet Beijing’s requirements even with the Yangtze River’s drastic decline due to severe drought.

The South-to-North Water Diversion Project stands as a monumental engineering feat, transferring over a billion cubic meters of water across a vast distance, akin to the stretch from Amsterdam to Rome.

This initiative highlights China’s proactive approach to water security and the potential ripple effects for neighboring regions.

Such monumental water management efforts uniquely position China, wielding considerable influence over much of Asia’s water distribution.

Undertakings like dam and hydropower plant constructions could amplify existing regional political nuances and even usher in new complexities.

A series of articles by Nikkei seeks to investigate the domino effect of water management decisions by upstream countries, especially when compounded by climate change factors.

Concerns have been voiced, especially from downstream regions, highlighting potential environmental repercussions and disruptions to both water resources and natural habitats, noted a water expert from a renowned Asian university.

The looming global water crisis is intensifying.

Projections from the UN suggest that by 2030, half of the world might grapple with water challenges, with the most immediate effects seen in food production and electricity provision.

With most of the global population, Asia is bracing for the most substantial impact, largely due to an ever-widening chasm between water supply and demand.

Many Asian countries adjacent to China heavily rely on the Third Pole’s glacial resources.

Climate change exacerbates the situation, hastening the melt rate of these glaciers, which spells potential long-term water shortages in Asia.

China’s water conundrum is intricate, with the bulk of its freshwater supply in the south, even as its northern industrialized belt grapples with limited water availability.

A previous Chinese Premier acknowledged the criticality of the water crisis for the nation’s continuity.

Emphasizing the significance of water management, China rolled out its maiden five-year plan dedicated to water security in 2021, aiming for holistic improvements in water supply, quality, and infrastructure.

The noteworthy South-to-North diversion project, with a US$62 billion price tag, is earmarked for further expansion to address China’s water distribution challenges.

China has ushered in around 100 water-centric initiatives over the past five years, some of which draw inspiration from past national aspirations dating back to the 1950s.

However, certain projects, including the ambitious Red Flag River proposition and a mega-dam project on the Yarlung Tsangpo, have garnered scrutiny due to potential geopolitical overtones.

Asian transboundary rivers often operate outside the purview of multilateral governance structures.

While China hasn’t embraced the 1997 U.N. Watercourses Convention, it’s engaged in approximately 50 bilateral water accords, as highlighted by a water law academic.

China’s approach to water management has occasionally sparked regional apprehensions. Notably, its water diplomacy exhibits varying strategies, reflecting broader geopolitical undertones.

A water security analyst emphasized China’s strategic alignment of water agreements with overarching diplomatic objectives.

Being at the helm of Asia’s hydro-landscape, China’s water stewardship holds profound consequences for innumerable individuals across the continent.

Collaboration, innovation, and adaptive strategies are pivotal to effectively counter escalating water challenges, as underscored by a noted author on Asian water dynamics.

Warnings have been sounded about rising competition over shared water resources, potentially catalyzing heightened regional tensions and confrontations.
