A Pakistani naval ship clipped an Indian warship in international waters near the North Arabian Sea, drawing a strong protest from India23. The Ministry of External Affairs (MEA) said the Pakistani unit acted in an unacceptable and unprofessional manner, contradicting Article 10 of the 1991 pact on advance notices for military moves23, a clause both sides have cited in prior communications as a framework for transparency and restraint at sea.

Pakistan denied details while India pressed Islamabad to observe the treaty and exercise due care in future operations31, signaling a firm push to ensure that such norms are respected and that incidents on sensitive maritime fronts do not escalate. The incident comes as both nations face heightened tensions and ongoing security considerations along key sea routes, with diplomacy stepped up as a direct result of the collision2331, reflecting the broader vulnerability of busy regional corridors to miscalculation and the importance each side places on maintaining reliable channels of communication.

India’s démarche was part of a broader pattern of diplomatic outreach in recent weeks, with officials emphasizing the need for calm, clarity, and compliance with existing agreements to prevent repeat episodes that could threaten regional stability. The clash prompted an immediate, high-level exchange of views, and the Indian government described the encounter as a serious breach of established norms, urging vigilance and restraint from the Pakistani side while continuing to monitor adherence to the pact.

India summoned Pakistan’s chargé d’affaires to convey the protest and to warn about adherence to agreements going forward31, signaling that New Delhi expects Islamabad to restore disciplined conduct in operations at sea and to reaffirm its commitment to the procedures designed to avert similar confrontations in the future.
