A template for security cooperation in the Indian Ocean
Context
-
India hosted the 7th National Security Advisor (NSA)-level meeting of the Colombo Security Conclave (CSC) on 20 November 2025.
-
Participants: India, Sri Lanka, Maldives, Mauritius, Bangladesh; Seychelles as new full member; Malaysia as guest.
-
The forum aims to deepen maritime and security cooperation in the Indian Ocean Region (IOR) amid shifting geopolitics, especially due to Chinaβs expanding footprint.
Background
-
CSC origins:
-
Started in 2011 as a trilateral security initiative between IndiaβSri LankaβMaldives.
-
Became inactive due to political transitions and divergent priorities.
-
Revived in 2020 with a broadened mandate: maritime security, counter-terrorism, trafficking, organised crime, cybersecurity.
-
-
Membership expansion:
-
Mauritius β full member (2022)
-
Bangladesh β full member (2024)
-
Seychelles β full member (2025)
-
Malaysia β guest participant (2025)
-
Importance of the Indian Ocean Security Landscape
-
Indian Ocean = vital trade and energy routes, 80% of global seaborne oil passes through.
-
Region witnessing new geopolitical shifts: Indo-Pacific strategies, Chinaβs maritime rise, naval competition.
-
Maritime security = tied with developmental needs (fisheries, tourism, blue economy).
Key Takeaways from the 2025 CSC Summit
1. Expansion & Regional Commitment
-
Seychelles joined as a full member β signals regional willingness to institutionalise security cooperation.
-
Malaysiaβs participation indicates potential for future inclusion β gradual enlargement of the security architecture.
2. Indiaβs Strategic Interests
-
India seeks stronger engagement with key maritime neighbours amid:
-
Chinaβs growing presence (βstring of pearlsβ, dual-use ports).
-
Fragmented IOR security architecture.
-
3. Centrality of Non-Traditional Security
-
CSCβs core areas:
-
Maritime safety & security
-
Counter-terrorism
-
Human trafficking & drug trafficking
-
Organised crime
-
Cybersecurity
-
Maritime domain awareness (MDA)
-
4. Coupling of Security & Development
-
For small Indian Ocean littorals:
-
Maritime security = tied to livelihoods, fisheries, blue economy, shipping, tourism.
-
Economic vulnerabilities drive dependence on external partners (including China).
-
Key Challenges for CSC
1. Divergence on the βChina Questionβ
-
India views Chinaβs IOR presence as a major security challenge.
-
Other members (Maldives, Sri Lanka, Mauritius, Bangladesh) view China mainly as a development partner.
-
Requires delicate diplomatic balance.
2. Lack of Institutionalisation
-
CSC currently functions as an NSA-level mechanism.
-
Lacks:
-
Permanent secretariat
-
Clear standard operating procedures (SOPs)
-
Operational coordination frameworks
-
-
Without institutional depth β inconsistency in long-term cooperation.
3. Domestic Political Uncertainty
-
Bangladeshβs political transitions may affect continuity in engagement.
-
Maldives & Sri Lanka have shown past fluctuations in foreign policy alignment.
4. Fragmented IOR Security Architecture
-
No single comprehensive Indian Ocean security institution exists.
-
Multiple overlapping groups β IORA, BIMSTEC, QUAD, IONS, IFC-IOR.
-
CSC must coordinate with larger Indo-Pacific frameworks.
Significance of CSC for India
-
Strengthens Indiaβs leadership in the subregional maritime security environment.
-
Helps counter encirclement & influence by China.
-
Enhances maritime domain awareness, joint exercises, intelligence sharing.
-
Reinforces Neighbourhood First + SAGAR (Security and Growth for All in the Region).
Way Forward
1. Institutional Strengthening
-
Establish a CSC Secretariat.
-
Regular ministerial-level meetings.
-
Joint working groups on: MDA, cyber, counter-terrorism, blue economy.
2. Balanced Approach to China
-
Address Indiaβs concerns without forcing choices on smaller neighbours.
-
Promote sustainable, transparent development alternatives.
3. Deepening Operational Cooperation
-
Joint patrols, naval exercises, coastal surveillance.
-
Capacity building in: cyber defence, maritime law enforcement, port security.
4. Integrating Development & Security
-
Promote blue economy initiatives.
-
Disaster risk reduction (NDRFβcoast guard coordination).
-
Maritime connectivity & supply-chain resilience.
5. Enhancing Resilience of Member States
-
Support political stability through development partnerships.
-
Encourage policy continuity through institutional mechanisms.
Conclusion
The CSC represents a promising subregional model for cooperative security in the Indian Ocean.
Its future success depends on:
-
managing divergent interests (especially around China),
-
strengthening institutional foundations, and
-
enhancing synergy between security and development objectives.
With India at its core, CSC can evolve into a cornerstone for a stable and cohesive Indian Ocean architecture.
