At UNGA, Shehbaz Sharif Warns Indus Water Diversion Threatens Regional War

Addressing world leaders at the 79th session of the United Nations General Assembly (UNGA) in New York, Pakistan Prime Minister Shehbaz Sharif declared that any unilateral move to divert the natural flow of the Indus River basin would be regarded as an act of war. The remarks underscore rising bilateral friction in South Asia over shared river systems and long-standing hydro-diplomacy mechanisms.

The Indus Waters Treaty (IWT), signed in September 1960 with the facilitation of the World Bank, has historically governed the distribution and usage of the six major rivers of the Indus Basin between India and Pakistan. Under the treaty, the waters of the eastern rivers—the Sutlej, Beas, and Ravi—are allocated primarily to India, while the western rivers—the Indus, Jhelum, and Chenab—are allocated largely to Pakistan, subject to specified domestic, non-consumptive, and run-of-the-river hydroelectric uses by upstream areas.

During his address from the UN podium, Sharif highlighted Pakistan's profound vulnerability to water stress and climate-induced disruptions, characterizing the Indus River system as the vital lifeline of the country's agrarian economy and millions of its citizens. The Pakistani Prime Minister asserted that Pakistan will protect its riparian rights under all circumstances, warning that any disruption or diversion of downstream flow could lead to severe regional instability and escalation.

In recent years, the Indus Waters Treaty has faced heightened procedural and technical disagreements. Disputes over upstream hydroelectric projects, such as the Kishanganga and Ratle plants in Jammu and Kashmir, have led to concurrent dispute-resolution proceedings involving a neutral expert and the Permanent Court of Arbitration at The Hague. Furthermore, discussions regarding formal treaty modifications and notifications to update the dispute-resolution framework have intensified diplomatic exchanges between New Delhi and Islamabad.

Beyond the water-sharing dispute, Sharif's address encompassed a range of international and regional security issues. The Prime Minister reiterated Pakistan's position on Jammu and Kashmir, calling for a resolution in accordance with relevant United Nations Security Council resolutions. He also underscored the necessity of de-escalation across multiple global conflict zones, advocating for sustained dialogue to address foundational geopolitical disputes.

Sharif also highlighted the importance of global economic stability and unhindered maritime commerce. He emphasized that vital international maritime chokepoints, including the Strait of Hormuz and the Bab al-Mandab Strait, must remain open and secure for uninterrupted global trade, energy transit, and maritime navigation amid heightened regional tensions across the Middle East.

Diplomatic observers note that transboundary water governance remains one of the most sensitive dimensions of South Asian regional relations. The Indus Waters Treaty has endured multiple conflicts over more than six decades, serving as a rare institutionalized mechanism of cooperation between India and Pakistan. However, compounding pressures from climate change, altered hydrological patterns, and modern infrastructural development continue to test the endurance of the historic pact.
