The operation began off the coast of Palawan, a crucial southwestern Philippine Island, with India’s INS Kiltan, an anti-submarine warfare corvette, and the Philippine Navy’s BRP Ramon Alcaraz, a guided-missile frigate, participating in coordinated manoeuvres.

Strategic Significance of the South China Sea Patrols

The South China Sea has long been a theatre of strategic contestation, with China’s growing military presence and expansive territorial claims raising concerns among ASEAN nations and global powers. The joint patrol by India and the Philippines serves as a clear message of regional solidarity and deterrence, especially amid recurring confrontations between Chinese vessels and Philippine maritime forces in the region’s contested waters.

Although India is not a claimant in the South China Sea disputes, it has consistently supported UNCLOS (United Nations Convention on the Law of the Sea) and the principle of freedom of navigation and overflight. This joint initiative reflects New Delhi's expanding role in Indo-Pacific maritime diplomacy and its willingness to stand with partners that are directly impacted by China's assertive behaviour in the region.

Deepening India–Philippines Defence Cooperation

The joint naval patrols are the result of deepening bilateral defence cooperation over the past few years, which has included:

1. The landmark $375 million BrahMos missile deal signed in 2022, supplying shore-based supersonic missile systems to the Philippine Marine Corps
2. High-level military and strategic dialogues
3. Port visits, training exchanges, and capacity-building exercises
4. India’s growing engagement with ASEAN’s maritime security architecture

This is also aligned with India’s Act East Policy and the Philippines’ Archipelagic Defence Strategy, which prioritise multi-layered defence partnerships, especially with democratic maritime nations.

Official Statements and Diplomatic Messaging

The Indian Embassy in Manila released a statement highlighting the objective of promoting "interoperability, regional stability, and a secure Indo-Pacific" through these joint maritime patrols. The Philippine Department of National Defence welcomed the Indian Navy's presence, affirming the joint patrols as a step toward “operationalising our growing strategic partnership.”

Defence analysts in both countries have emphasised the symbolic and operational value of this partnership. Not only does it expand India’s naval reach, but it also provides the Philippines with a credible partner in its efforts to defend its sovereign rights within its Exclusive Economic Zone (EEZ).

A Calculated Move Amid Rising Tensions with China

This development comes in the backdrop of growing Philippines-China tensions, especially around Second Thomas Shoal, where Chinese coast guard vessels have increasingly harassed Philippine supply missions. It also follows the Philippines' recent decision to expand U.S. access to bases under the EDCA (Enhanced Defence Cooperation Agreement), a move that has drawn China’s ire.

India’s involvement, though less direct, holds powerful symbolic and strategic weight. It is part of a broader regional trend of middle powers cooperating to push back against unilateralism and to ensure that the Indo-Pacific remains free, open, and inclusive.

The Indo-Pacific Vision: Collaborative and Inclusive

The India-Philippines joint patrols also align with New Delhi’s broader vision of the Indo-Pacific, which champions:

1. Multilateralism over militarism
2. Capacity building and technology sharing
3. Support for Digital Public Infrastructure (DPI)
4. Security cooperation based on shared democratic values

India has already conducted bilateral and multilateral naval exercises with countries like Vietnam, Indonesia, Australia, and Japan, and remains an active participant in forums like QUAD, IONS (Indian Ocean Naval Symposium), and the ADMM-Plus.

Looking Ahead: Future of India-Philippines Naval Engagement

The success of the inaugural joint patrol opens the door for deeper collaboration, including:

1. Regular bilateral maritime exercises
2. Logistics agreements (like the India-Vietnam one signed earlier)
3. Technology and training partnerships in cyber, space, and undersea domains
4. A possible defence attaché office for India in Manila

As India scales up its defence exports and the Philippines upgrades its military capabilities, this cooperation is poised to play a central role in the regional security architecture of Southeast Asia.

Conclusion: A Strategic Milestone for Indo-Pacific Security

The launch of joint India-Philippines naval patrols in the South China Sea represents a strategic milestone in Indo-Pacific security cooperation. It reflects not only a maturing bilateral relationship but also a shared commitment to preserving peace, ensuring maritime stability, and defending the principles of international law.

In an era where great-power competition threatens to destabilise maritime norms, such partnerships offer a credible counterbalance, driven not by domination, but by cooperation, trust, and shared vision.
