Indus Waters Treaty dispute has returned to the centre of Pakistan-India tensions after Deputy Prime Minister and Foreign Minister Ishaq Dar warned that any move affecting Pakistan’s water rights could carry serious consequences for regional peace.
Speaking at an international seminar on the Indus Waters Treaty in Islamabad, Dar said shared waters should not be used as a political tool and urged India to address disputes through dialogue, diplomacy and the mechanisms provided under the treaty. His remarks came as Pakistan continues to challenge India’s decision to place the 1960 water-sharing agreement in abeyance.
Dar said Pakistan viewed the protection of its water resources as a matter of national interest. He argued that the Indus Waters Treaty remains legally binding and that one party cannot unilaterally suspend or terminate obligations under an agreement that does not expressly provide for such action.
The comments reflect Islamabad’s broader position that the treaty should remain insulated from political and security disputes between the two countries. India, meanwhile, has linked its decision to hold the treaty in abeyance to its stated concerns over cross-border terrorism following the April 2025 attack in Pahalgam, in Indian-administered Kashmir. Pakistan has denied involvement in the attack, as their is no proof backing india’s claim.
Indus Waters Treaty dispute raises legal and diplomatic questions
The Indus Waters Treaty dispute is not new, but the present standoff is among the most serious challenges the agreement has faced since it was signed in 1960. Brokered by the World Bank, the treaty divided the use of the Indus river system between India and Pakistan. India was allocated the eastern rivers, Ravi, Beas and Sutlej, while Pakistan received rights over the western rivers, Indus, Jhelum and Chenab, subject to certain uses allowed to India.
For decades, the agreement survived periods of war, military confrontation and diplomatic breakdown. That history has often led analysts to describe it as one of the more durable arrangements between the two nuclear-armed neighbours.
The current crisis, however, has placed renewed pressure on the treaty. India announced in 2025 that the treaty would be held in abeyance, saying its position would continue until Pakistan credibly and irrevocably ended support for cross-border terrorism. Pakistan rejected both the allegation and the legal basis for holding the treaty in abeyance.
At the Islamabad seminar, Pakistani officials framed the matter as a question of international law, regional stability and human security. Dar said water should remain a bridge between nations and should be managed through cooperation and respect for legal obligations.
Pakistan says water rights must not be disrupted
Pakistan’s position is that any attempt to divert, interrupt or reduce water allocated to it under the Indus Waters Treaty would be unacceptable. Dar reiterated that Pakistan would defend its rights under the agreement and would use available legal and diplomatic channels to do so.
Other Pakistani officials at the seminar also warned against what they described as the politicisation of shared rivers. Climate Change Minister Musadik Malik said accepting unilateral suspension of water agreements could weaken confidence in international arrangements governing transboundary resources. Information Minister Attaullah Tarar described the Indus system as central to Pakistan’s agriculture, economy and livelihoods.
The concern in Pakistan is rooted in the country’s dependence on the Indus basin. The river system supports irrigation, food production, hydropower and rural livelihoods across large parts of the country. Any disruption, or even uncertainty over water flows, can therefore carry significant economic and political consequences.
Pakistan has also raised concerns about water flows in the Chenab River, with officials alleging that recent reductions were inconsistent with treaty obligations. India had not issued an immediate public response to those specific claims at the time of the latest seminar.
India links treaty abeyance to security concerns
India’s position is that the Indus Waters Treaty cannot be treated separately from its wider security concerns. New Delhi placed the treaty in abeyance after the Pahalgam attack in April 2025, which killed 26 tourists in Indian-administered Kashmir. India blamed Pakistan-based militants for the attack.
Pakistan denied responsibility and said it was prepared to participate in an independent investigation. The incident sharply worsened relations between the two countries, leading to wider diplomatic and security tensions.
India has argued that its approach reflects the principle that normal cooperation cannot continue in the presence of terrorism. Its official position has been framed around the phrase that “blood and water cannot flow together,” suggesting that treaty cooperation depends on Pakistan addressing India’s security concerns.
Pakistan rejects this linkage, saying the Indus Waters Treaty is a binding international agreement and cannot be suspended because of unrelated political or security disputes. Islamabad has also argued that water-sharing obligations are too important to be made conditional on bilateral tensions.
Why the Indus Waters Treaty matters for South Asia
The Indus Waters Treaty 1960 is significant because it governs one of the world’s most politically sensitive river systems. The Indus basin crosses borders, sustains millions of people and supports agriculture in a region already exposed to climate stress, population growth and water scarcity.
For Pakistan, the western rivers are essential to irrigation and food security. For India, the treaty has long shaped the design and operation of hydropower projects on the western rivers, including limits and procedural requirements that have been the subject of repeated disputes.
The treaty also contains dispute-resolution mechanisms, including the role of neutral experts and courts of arbitration. Both countries have previously used these mechanisms in relation to hydropower projects and design questions.
The World Bank’s role is limited. It facilitated the original treaty and has certain procedural responsibilities, but it does not decide the merits of disputes between India and Pakistan. This makes bilateral engagement and treaty-based mechanisms central to any sustainable resolution.
Legal mechanisms remain central to the Pakistan India water row
The Pakistan India water row is likely to remain legally complex. Pakistan maintains that India’s decision to hold the treaty in abeyance has no legal effect and that the treaty continues to bind both parties. India maintains that its step is tied to Pakistan’s conduct and broader security conditions.
The disagreement therefore has two layers. The first concerns legal interpretation: whether a party can suspend performance of treaty obligations in the circumstances claimed by India. The second concerns factual and political allegations, including India’s claims about cross-border terrorism and Pakistan’s denial of those claims.
Because the two sides disagree on both levels, neutral wording is important. Pakistan says India is acting unlawfully. India says its action is justified by security concerns. The treaty’s dispute-resolution structures, along with diplomatic engagement, remain the formal avenues through which such claims can be addressed.
Climate pressure makes the dispute more sensitive
The dispute comes at a time when climate change is intensifying water-related risks across South Asia. Glacial melt, irregular rainfall, floods, droughts and rising demand are placing additional pressure on river systems. This makes the Indus Waters Treaty dispute more than a bilateral legal disagreement; it is also a regional water security concern.
Pakistani officials argued at the seminar that shared rivers should be protected from political confrontation precisely because water scarcity is becoming more severe. Their position is that the treaty offers a stabilising framework at a time when climate risks make cooperation more urgent.
For India, water infrastructure and hydropower development remain important domestic priorities, particularly in regions connected to the Indus basin. This creates a recurring tension between development, treaty limits, security considerations and downstream concerns.
Dialogue remains the safest path forward
The latest statements from Islamabad show that Pakistan intends to keep pressing the issue internationally and through legal channels. At the same time, the absence of active treaty cooperation increases the risk of miscalculation between two countries with a long history of conflict.
A durable outcome is unlikely without some form of structured engagement. The treaty was designed to separate water-sharing from wider political disputes, but the present crisis has brought those issues together in a way that could make de-escalation more difficult.
For Pakistan, the priority is to ensure uninterrupted access to water under the treaty. For India, the priority is to connect future cooperation with its security concerns. For the wider region, the central issue is whether a long-standing water-sharing framework can withstand renewed political pressure.
The Indus Waters Treaty dispute therefore remains a test of diplomacy, legal restraint and regional responsibility. However strongly both countries disagree, shared rivers leave little room for miscalculation. The most constructive path remains dialogue, treaty-based dispute resolution and careful avoidance of language or actions that could deepen an already fragile situation.
