SAGAR, an acronym for "Security and Growth for All in the Region" that also means "ocean" in Hindi, is the framework articulated by Prime Minister Narendra Modi during his visit to Mauritius on 12 March 2015, while commissioning the offshore patrol vessel CGS Barracuda built by India for the Mauritian Coast Guard. The doctrine was not codified in any treaty or statute; it emerged as a declaratory foreign-policy vision that consolidated India's longstanding interests in the Indian Ocean Region (IOR) into a single conceptual umbrella. It rests on the recognition that the Indian Ocean carries roughly half of the world's container traffic and a substantial share of global oil shipments through chokepoints such as the Strait of Hormuz, the Bab-el-Mandeb, and the Strait of Malacca, and that India's geographic centrality confers both vulnerability and responsibility. SAGAR drew intellectual lineage from earlier formulations, including Prime Minister Manmohan Singh's references to India as a "net security provider" in the region articulated around 2011-2013.
Operationally, SAGAR is built on five interlocking pillars that the Ministry of External Affairs and the Indian Navy have elaborated in successive statements. The first is safeguarding India's own mainland and island territories and securing its interests at sea. The second is deepening economic and security cooperation with friendly littoral states, particularly through capacity-building and capability-enhancement. The third is collective action to address natural disasters and maritime threats such as piracy, terrorism, and trafficking. The fourth is the pursuit of sustainable regional development and the blue economy. The fifth is engagement with extra-regional powers in a manner consistent with regional primacy resting with the littoral states themselves. These pillars translate into concrete instruments: hydrographic surveys, white-shipping information-sharing agreements, coastal radar chains, training of partner navies, and the provision of platforms such as patrol vessels and Dornier aircraft.
A defining mechanic of SAGAR is its emphasis on capacity-building over basing. Rather than constructing a network of military bases, India has pursued logistics arrangements, coastal surveillance radar installations in countries including Mauritius, Seychelles, Sri Lanka, and Maldives, and the gifting or sale of naval assets. The Indian Navy's establishment of the Information Fusion Centre – Indian Ocean Region (IFC-IOR) at Gurugram in December 2018 institutionalized maritime domain awareness, hosting international liaison officers and aggregating white-shipping data. India's Mission-Based Deployments, under which warships maintain near-continuous presence across key IOR chokepoints, give the doctrine an operational spine. SAGAR also operates through plurilateral architecture, including the Indian Ocean Rim Association (IORA), the Indian Ocean Naval Symposium (IONS), and the trilateral maritime security cooperation with Sri Lanka and Maldives, expanded to include Mauritius and Bangladesh as observers.
Contemporary practice illustrates the doctrine's reach. New Delhi delivered the Dornier aircraft and patrol vessels to Mauritius and Seychelles, conducted the Mission Sagar humanitarian missions during the COVID-19 pandemic in 2020 delivering medical supplies to Maldives, Mauritius, Madagascar, Comoros, and Seychelles, and signed logistics agreements with France (2018) and other partners enabling reciprocal access to facilities such as Réunion and Djibouti. The development of the Agalega facility in Mauritius and India's involvement at Sittwe in Myanmar and the Chabahar port in Iran reflect the connectivity dimension. At the SAGAR's tenth anniversary in March 2025, during Modi's visit to Mauritius, the framework was rearticulated as MAHASAGAR ("Mutual and Holistic Advancement for Security and Growth Across Regions"), signaling an expansion of ambition from the IOR to the broader Global South.
SAGAR is distinct from, though complementary to, several adjacent concepts. It is narrower than the Indo-Pacific construct, which extends Indian strategic attention eastward to the western Pacific and underpins India's participation in the Quadrilateral Security Dialogue (Quad) with the United States, Japan, and Australia. SAGAR's geographic core remains the Indian Ocean, and its idiom is cooperative and developmental rather than overtly balancing. It differs from China's Maritime Silk Road and the broader Belt and Road Initiative in eschewing a creditor-debtor model and emphasizing partner ownership; Indian officials present SAGAR as a counterpoint to what critics term "debt-trap diplomacy." It is also distinct from the Necklace of Diamonds, an analyst-coined concept describing India's encirclement response to China's "String of Pearls."
The doctrine faces real constraints and contested interpretations. India's resource base for sustained blue-water presence remains limited relative to the People's Liberation Army Navy's expanding IOR footprint, including its base at Djibouti and submarine deployments. Domestic political shifts in partner states—the 2023-2024 "India Out" campaign in Maldives under President Mohamed Muizzu, which led to the withdrawal of Indian military personnel in 2024—exposed the fragility of relationships SAGAR depends upon. Questions also persist over whether SAGAR's cooperative branding adequately addresses the hard-power competition reshaping the region, and whether the 2025 MAHASAGAR rebranding represents genuine widening or rhetorical inflation.
For the working practitioner, SAGAR functions as the organizing rubric through which India's maritime diplomacy, naval deployments, and development assistance in the littoral are framed and justified. Desk officers tracking South Asia, analysts assessing China-India competition, and journalists covering Indian Ocean summitry must read Indian statements on port projects, training missions, and disaster relief against the SAGAR template. For UPSC and policy examinations, SAGAR anchors discussions of India's neighbourhood policy, maritime security, and the blue economy, and its evolution into MAHASAGAR marks the doctrine's transition from regional vision to Global South engagement strategy.
