BackgroundCore Concept

Background

India and Japan share a Special Strategic and Global Partnership, one of the most substantive bilateral frameworks India maintains in the Indo-Pacific. This partnership has evolved steadily over two decades, moving from trade and investment ties to a comprehensive defence and security relationship. The foundation rests on shared strategic interests: both countries favour a rules-based international order, freedom of navigation, and a stable Indo-Pacific free from coercive unilateral actions.

India's Act East Policy — an upgrade of the earlier Look East Policy — repositioned engagement with the Asia-Pacific as a core foreign-policy priority. Japan is a central pillar of this policy. Both countries are members of the Quad grouping alongside the United States and Australia, which has institutionalised multilateral cooperation on maritime security, critical technologies, and supply-chain resilience. India's MAHASAGAR vision (Mutual and Holistic Advancement for Security and Growth Across Regions) provides the broader conceptual framework for India's cooperative, non-coercive approach to the Indian Ocean and Indo-Pacific.

The India-Japan defence relationship has deepened through structured bilateral exercises, defence equipment transfers, and logistics arrangements. Japan's Japan Maritime Self-Defense Force (JMSDF) and the Indian Navy have progressively expanded interoperability. The two countries also cooperate under the Indo-Pacific Logistics Network (IPLN), a humanitarian and disaster-relief coordination mechanism.

The Topic Explained

Sea Lines of Communication (SLOCs) are the maritime routes through which trade, energy, and military logistics flow. The Indo-Pacific hosts some of the world's most critical SLOCs — through the Strait of Malacca, the South China Sea, and the Indian Ocean. India and Japan are both heavily dependent on these routes for energy imports and export-led growth. Disruption to SLOCs — through piracy, territorial disputes, or coercive naval posturing — directly threatens both economies.

Maritime Domain Awareness (MDA) is the ability to understand and monitor all activities in the maritime environment that could affect security, safety, the economy, or the environment. MDA is the foundation of effective naval cooperation. Sharing MDA data between India and Japan allows both navies to track vessels, detect threats, and coordinate responses in real time across a vast oceanic expanse.

The Memorandum of Arrangement on Maritime Security Cooperation signed during this bilateral meeting establishes a formal framework for operational cooperation. …
