Pakistan Takes Indus Waters Dispute to UN Security Council, Seeks Pressure on India Over Indus Waters Treaty

New Delhi: The dispute between India and Pakistan over the Indus Waters Treaty (IWT) has once again reached the international diplomatic arena, with Islamabad seeking intervention from the United Nations Security Council.

Pakistan has urged the UN Security Council to press India to implement the 1960 Indus Waters Treaty and comply with the findings of the Court of Arbitration constituted under the treaty. The move comes after the Court of Arbitration issued an award on 31 August 2026 concerning the status of the treaty following India’s decision to place it in abeyance. The Permanent Court of Arbitration (PCA) confirmed that the award and an interim-measures order had been issued in the case brought by Pakistan.

Ishaq Dar writes to the United Nations

Pakistan’s Deputy Prime Minister and Foreign Minister Ishaq Dar has raised the matter through a letter to UN Secretary-General António Guterres. Islamabad has asked the international community to take note of what it describes as the serious consequences of any interruption, diversion or restriction of water flows covered by the treaty.

Pakistan maintains that the Indus Waters Treaty continues to remain legally binding and has argued that India should resume cooperation, information-sharing, consultations and other mechanisms provided under the agreement.

Islamabad highlights the arbitration ruling

The 31 August decision has become a central part of Pakistan’s diplomatic argument. According to the PCA’s official case record, the Court of Arbitration issued an Award on the Status of the Indus Waters Treaty as well as an order concerning interim measures related to the Ratle Hydroelectric Plant.

Pakistan has interpreted the decision as supporting its position that India’s unilateral decision to place the treaty in abeyance cannot remove the treaty’s obligations.

India, however, has rejected the proceedings and questioned the jurisdiction of the Court of Arbitration. The Ministry of External Affairs has maintained that the arbitration body has no jurisdiction over India’s sovereign decision and that India’s decision to keep the treaty in abeyance remains in force.

Why is the Indus Waters Treaty so important to Pakistan?

For Pakistan, the dispute is closely connected with agriculture, food security and the wider economy. The Indus river system is central to the country’s irrigation network and supports a large population dependent on agriculture and related activities.

Islamabad has therefore presented the issue not merely as a bilateral legal dispute but as a matter involving humanitarian, economic and regional-security concerns.

Pakistan has also warned that any attempt to stop, divert, restrict or manipulate what it considers its treaty-based water share could have consequences beyond the immediate dispute.

Pakistan seeks international pressure on New Delhi

In its latest diplomatic push, Islamabad has called for India to:

• maintain implementation of the Indus Waters Treaty;
• comply with the applicable arbitration decisions;
• avoid measures affecting Pakistan’s treaty-based water flows;
• resume the treaty’s mechanisms for cooperation and information exchange;
• and resolve outstanding differences through established legal and diplomatic channels.

Pakistan has also argued that allowing countries to disregard international water agreements for political reasons could undermine confidence in cross-border water treaties elsewhere.

The two countries remain sharply divided

The dispute reflects fundamentally different positions from New Delhi and Islamabad.

Pakistan argues that the treaty remains binding and that the arbitration mechanism continues to operate. Pakistan’s Foreign Ministry has publicly said it considers the 31 August decision an important reaffirmation of the treaty.

India, meanwhile, has rejected the arbitration proceedings and continues to maintain that its decision regarding the treaty remains in force.

The disagreement therefore extends beyond the question of water sharing. It now involves competing interpretations of the treaty, the jurisdiction of the arbitration mechanism and the consequences of India’s decision to place the agreement in abeyance.

Islamabad’s earlier ‘act of war’ warning

Pakistan had previously warned that any attempt to stop or divert water allocated to it under the treaty could be treated as an act of war. A Pakistani government document submitted to the United Nations in 2025 recorded this position in the context of Islamabad’s response to India’s decision on the treaty.

The latest move at the United Nations shows that Pakistan is continuing to pursue the dispute through international diplomatic and legal forums.

For India and Pakistan, the Indus Waters Treaty has consequently become one of the most sensitive issues in their already strained bilateral relationship.
