Indian Ocean Region & India's Path to Maritime Leadership

For centuries, the Indian Ocean has been a cradle of civilizations, trade, and cultural exchanges, linking the shores of East Africa, the Middle East, South Asia, and Southeast Asia. This vast maritime space has remained central to India’s economic and security interests, from the ancient Chola naval expeditions to the bustling modern shipping lanes.
While the Indo-Pacific concept gained strategic relevance in the last decade, recent geopolitical upheavals, such as the Ukraine war (2022) and the ongoing West Asia conflict (2023), have shifted global attention back to the Indian Ocean Region (IOR).

The Indian Ocean, the third-largest ocean in the world, spans about 70.56 million sq. km, covering nearly 20% of the Earth’s surface. It is bordered by Asia (north), Africa (west), Australia (east), and the Southern Ocean (south). This ocean plays a pivotal role in global trade, security, and climate regulation.

Significance of Indian Ocean for India

Geostrategic Importance: A vital maritime highway through which 80% of global oil shipments pass, it is crucial for India’s regional and global strategy.
Economic & Trade Lifeline: Facilitates 90% of India’s trade by volume and 70% by value, making it indispensable for economic growth.
Energy & Resource Security: Ensures access to vital crude oil imports from West Asia and Africa, along with extensive reserves of hydrocarbons and rare earth minerals.
Maritime Security & Defence: India’s 7,516.6 km coastline, along with Andaman & Nicobar and Lakshadweep Islands, enhances defence against piracy, illegal fishing, and external threats.
Diplomatic & Strategic Leadership: India’s SAGAR vision, IPOI, and MAHASAGAR doctrine promote regional stability, supported by the Quad, IORA, and BIMSTEC.
Climate & Disaster Resilience: Strengthens early warning systems, disaster response, and humanitarian aid in a cyclone-prone region.
Historical & Cultural Linkages: Reinforces India’s maritime ties with Africa, the Middle East, and Southeast Asia, enhancing diplomatic and economic outreach.

India’s Recent Initiatives in the Indian Ocean Region (IOR)

MAHASAGAR Doctrine (2025): Strengthens India’s commitment to regional security and economic cooperation, building upon the SAGAR (Security and Growth for All in the Region) vision.
Naval Modernization & Indo-Pacific Maritime Collaboration: Commissioning of INS Vikrant, expansion of naval exercises like MILAN and Malabar, and logistics agreements with France, Japan, and Australia to enhance India’s naval reach.
Expansion of Coastal Surveillance Systems (CSS): Deployment of radar stations in Mauritius, Seychelles, Sri Lanka, and Maldives to enhance maritime domain awareness and counter illegal activities.
Greater Focus on Indo-Pacific Strategy: Expansion of the Indo-Pacific Oceans Initiative (IPOI) with increased engagement from EU nations and ASEAN, emphasising maritime security, connectivity, and sustainable development.
Infrastructure Development in Key Island Nations: Investments in Chabahar Port (Iran), Sittwe Port (Myanmar), and Sabang Port (Indonesia) to strengthen trade connectivity and counterbalance China’s BRI influence.
Mission SAGAR: Humanitarian assistance and disaster relief (HADR) missions in Sri Lanka, Maldives, Seychelles, Madagascar, and Mozambique, showcasing India’s role as a net security provider.
Deep-Sea Exploration and Blue Economy Initiatives: Launch of the Samudrayaan mission for deep-sea mining and the Deep Ocean Mission (DOM) to explore polymetallic nodules and marine biodiversity conservation.

Key Challenges in the Indian Ocean Region

Geopolitical Rivalries and Strategic Competition

Current Affairs

US-China Power Struggle: India’s Strategic Dilemma

The US Indo-Pacific Strategy aims to counter China’s String of Pearls Strategy, which involves constructing dual-use ports in Djibouti, Gwadar (Pakistan), Hambantota (Sri Lanka), and Kyaukpyu (Myanmar), creating strategic encirclement around India.
China’s Maritime Silk Road, a part of the Belt and Road Initiative (BRI), is enhancing its naval presence in the Indian Ocean, leading to a security dilemma for India.

Rising Influence of External Players

France is strengthening its Indo-Pacific presence with military bases in Reunion and Mayotte.
Russia, Iran, and Türkiye are increasing their maritime ambitions, further complicating the regional security landscape.

Regional Conflicts and Tensions

India-Pakistan maritime boundary disputes continue to be a challenge.
China-Philippines tensions in the South China Sea have led Manila to seek India’s involvement in the “Squad” alliance to counter Beijing’s assertiveness.

Maritime Security Threats: Emerging Challenges

Piracy and Maritime Terrorism: The resurgence of piracy off the Somali coast threatens global trade routes, while terrorist networks increasingly exploit sea routes for arms and drug smuggling.
Illegal, Unreported, and Unregulated (IUU) Fishing: Foreign trawlers intruding into India’s Exclusive Economic Zone lead to overfishing, marine biodiversity loss, & economic hardship for coastal people.
Climate Change & Natural Disasters: Rising sea levels endanger coastal cities & island nations like the Maldives & Bangladesh, while increasing cyclones and tsunamis disrupt trade and displace populations.

Institutional & Policy Challenges

Weak Regional Mechanisms: IORA struggles with funding & institutional gaps, limiting its impact, while BIMSTEC faces setbacks due to India-Bangladesh Teesta water disputes & Myanmar’s political crisis.
Limited Naval Capabilities: India’s two aircraft carriers (INS Vikrant, INS Vikramaditya) contrast with China’s three (Liaoning, Shandong, Fujian), highlighting the need for stronger surveillance, modernisation, and bases like Chabahar and Assumption Island.

Way Forward

Strengthening Strategic & Regional Partnerships

Deepen ties with key nations like Mauritius, Sri Lanka, Indonesia, Australia, UAE, and South Africa while enhancing maritime diplomacy through IORA, BIMSTEC, and SAGAR initiatives.
Expand joint naval exercises such as MILAN, SIMBEX, AUSINDEX, & Malabar to improve interoperability.

Enhancing Maritime Security & Naval Capabilities

Strengthen coastal security and real-time surveillance through IFC-IOR and Andaman & Nicobar strategic assets.
Expand naval power with IAC-2 aircraft carrier, indigenous submarines, and anti-submarine warfare systems to counter rising threats.

Advancing Blue Economy & Climate Resilience

Promote sustainable fishing, deep-sea exploration, and ocean resource management to balance economic growth with conservation.
Develop climate-resilient coastal infrastructure to mitigate the impact of rising sea levels and cyclones.

“Whoever controls the Indian Ocean will control global trade.” Guided by the vision of SAGAR and the MAHASAGAR doctrine, India is reinforcing its maritime strategy to safeguard regional stability, economic prosperity, and security.
