Introduction
The India-Japan 'Special Strategic and Global Partnership' has progressively transitioned from reactive, balance-of-power containment toward securing regional maritime public goods across the Indo-Pacific. Underpinned by Article 51(c) of the Indian Constitution, which enjoins respect for international law and treaty obligations, India's Indo-Pacific Oceans Initiative (IPOI) and SAGAR framework closely align with Japan's Free and Open Indo-Pacific (FOIP) vision to address both traditional and non-traditional maritime challenges.
Evolution Beyond Anti-China Deterrence
While strategic convergence initially accelerated around shared security anxieties, India and Japan have consciously broadened their maritime engagement into capacity building, disaster management, and the protection of the global maritime commons. The framework reflects a transition towards joint custodianship of Sea Lines of Communication (SLOCs) stretching from the Western Indian Ocean to the Western Pacific.
Key Provisions of the Maritime Defence Pact
The Memorandum of Arrangement on Maritime Security Cooperation institutionalises this multi-stakeholder and comprehensive approach through several foundational pillars:
- Reciprocal Logistics and Operational Support: The pact fully operationalises the 2020 Acquisition and Cross-Servicing Agreement (ACSA), expanding routine naval access to designated ports, mutual maintenance facilities, and ship-repair capabilities across both nations' maritime jurisdictions.
- Enhanced Maritime Domain Awareness (MDA): It deepens real-time operational intelligence sharing and white-shipping data exchange, integrating maritime surveillance frameworks via India’s Information Fusion Centre–Indian Ocean Region (IFC-IOR) to monitor suspicious vessel movements and illicit trafficking.
- Standardised HADR and Search & Rescue (SAR): The agreement codifies joint operating protocols for civilian evacuation, maritime emergency response, and rapid Humanitarian Assistance and Disaster Relief (HADR) deployments during cyclonic and seismic disruptions.
- Mine Countermeasures (MCM) Synergies: It establishes specialized operational coordination, information sharing, and mine-clearance drills between the Indian Navy and the Japan Maritime Self-Defense Force (JMSDF) to ensure the uninterrupted transit of vital SLOCs.
- Defence Co-Development and Technology Transfer: Capitalising on Japan’s relaxed defence export guidelines, the agreement formalises the co-development and co-production of the UNICORN (Unified Complex Radio Antenna) stealth mast with Bharat Electronics Limited (BEL), strengthening domestic naval design under the 'Make in India' initiative.
Upholding the Rules-Based International Order
The pact serves as an operational instrument reinforcing the United Nations Convention on the Law of the Sea (UNCLOS 1982), ensuring freedom of navigation, overflight, and unimpeded commerce without unilateral territorial coercion.
Conclusion
To fully unlock the potential of this partnership, both nations should advance into Underwater Domain Awareness (UDA) and deepen multilateral minilateralism anchored in ASEAN centrality. By prioritizing capacity-building and transparent governance, India and Japan can anchor an open, inclusive, and resilient Indo-Pacific security architecture.
