Water has always occupied a unique place in international relations because it is one of the few natural resources that ignores political frontiers. Rivers rise in one country, flow through another and sustain millions of people before reaching the sea. Their management therefore depends not only on engineering and environmental policy but also on diplomacy, international law and mutual trust. In an era increasingly defined by climate change, population growth and water scarcity, agreements governing shared rivers have become more valuable than ever. The renewed international discussion surrounding the Indus Waters Treaty reflects this reality. What was once viewed largely as a bilateral arrangement between India and Pakistan is now attracting broader global attention as governments, legal scholars and strategic experts recognise that disputes over water can carry consequences extending far beyond the borders of the countries directly involved.
The recent remarks by Dr Victor Gao, Vice President of the Centre for China and Globalization, have introduced another dimension to this debate. Speaking at an international seminar on the Indus Waters Treaty, he argued that China and Pakistan could cooperate more closely to strengthen the treaty and improve its implementation. His proposal reflects an emerging understanding that transboundary water management is no longer solely the concern of neighbouring states but forms part of a wider regional and international conversation about sustainability, humanitarian responsibility and collective security. While the practical implications of his proposal remain open to debate, his intervention highlights the growing international interest in preserving one of the world’s longest-standing water-sharing agreements.
The Indus Waters Treaty occupies a remarkable place in the history of international diplomacy. Signed in 1960 after years of negotiations, it has survived multiple wars, diplomatic crises and prolonged periods of hostility between India and Pakistan. Few international agreements have demonstrated such resilience under equally difficult political conditions. The treaty has endured precisely because successive governments recognised that water should remain insulated from political disputes wherever possible. It established clear mechanisms for managing shared rivers, resolving disagreements and maintaining communication even when broader diplomatic relations deteriorated. Its longevity has often been cited by international observers as evidence that carefully designed legal frameworks can withstand geopolitical tensions.
That reputation, however, cannot be taken for granted. Recent political rhetoric questioning the future of the treaty has generated understandable concern among legal experts and policymakers alike. Statements suggesting that water supplies could become instruments of political pressure have prompted renewed debate over whether shared natural resources should ever be used to advance strategic objectives. Such discussions extend well beyond South Asia because they touch upon principles that underpin international cooperation across the world. Rivers such as the Nile, the Mekong, the Danube and the Jordan all require careful management between states with differing political interests. If the principle that shared water should remain protected from political confrontation begins to weaken in one region, the implications may resonate elsewhere.
It is against this backdrop that Dr Gao’s strongest argument deserves careful consideration. He described the deliberate interruption of water supplies as an act against humanity, emphasising that access to water represents a fundamental human necessity rather than merely a strategic asset. While his language reflects a firm political position, the broader humanitarian principle is widely recognised in international law. Water is indispensable for drinking, agriculture, sanitation, public health and economic survival. Millions of people depend upon predictable river flows for their livelihoods, particularly in agricultural economies where irrigation supports food production and rural employment. Any disruption to these systems inevitably affects ordinary civilians long before it influences political leaders.
The humanitarian dimension of water management has become even more important as climate change intensifies existing pressures. Rising temperatures, unpredictable rainfall patterns, melting glaciers and increasing demand for freshwater are placing unprecedented strain on river systems across Asia and beyond. South Asia, home to nearly a quarter of the world’s population, already faces mounting challenges associated with water security. Scientific studies consistently warn that climate-related changes will make cooperation between riparian states increasingly essential rather than less so. In such circumstances, preserving established legal mechanisms becomes a matter not simply of diplomatic convenience but of long-term regional resilience.
Dr Gao also argued that threatening to restrict water flows risks undermining both regional stability and the legal foundations upon which the Indus Waters Treaty rests. Whether viewed from a political, legal or humanitarian perspective, his observation raises broader questions about the relationship between power and responsibility. Upper-riparian states naturally exercise considerable influence over river systems originating within their territory. International water law has therefore evolved around principles intended to balance sovereign rights with corresponding obligations. These include equitable and reasonable utilisation of shared water resources, avoidance of significant harm to downstream states and cooperation through information sharing and consultation. Although disagreements over interpretation frequently arise, these principles provide an internationally recognised framework for reducing the likelihood of conflict.
Another important aspect of Dr Gao’s remarks concerned reciprocity. He argued that states should avoid actions they themselves would regard as unacceptable if their positions were reversed. This principle has long informed international diplomacy because relationships between upstream and downstream countries are rarely fixed across different river basins. A country occupying an upstream position in one watershed may itself depend upon the responsible conduct of another upstream neighbour elsewhere. Such interdependence encourages restraint and reinforces the practical importance of maintaining universally accepted standards of behaviour rather than relying solely on immediate strategic advantage.
The suggestion that China could assume a greater role in discussions surrounding the wider Indus basin inevitably introduces new geopolitical considerations. China itself is an upper-riparian state on several major Asian rivers and has substantial experience managing complex transboundary water issues. Any expanded regional cooperation would therefore require careful diplomacy, transparency and respect for existing legal arrangements. Such proposals are unlikely to command immediate consensus, and differing political perspectives will inevitably shape future discussions. Nevertheless, the broader principle underlying Dr Gao’s proposal—that regional challenges increasingly require regional dialogue—reflects a reality that extends beyond any single river basin.
The endurance of the Indus Waters Treaty over more than six decades demonstrates that even deeply divided neighbours can maintain practical cooperation when shared interests demand it. That achievement should not be underestimated. As climate pressures intensify and regional populations continue to grow, preserving rules-based mechanisms for managing shared rivers will become even more important. International agreements cannot eliminate political disputes, but they can prevent those disputes from endangering the essential resources upon which civilian populations depend.
Dr Victor Gao’s intervention ultimately serves as a reminder that water should never become another casualty of geopolitical rivalry. Whether or not his proposals regarding expanded China-Pakistan cooperation gain wider international support, his broader message reinforces an enduring principle of international governance: shared rivers require shared responsibility. Protecting them demands respect for international agreements, commitment to humanitarian values and an unwavering preference for dialogue over confrontation. In a century where freshwater is likely to become one of the world’s most strategic resources, safeguarding cooperation may prove every bit as important as safeguarding the water itself.
