Introduction
Over 80% of global seaborne trade passes through the Indian Ocean (UNCTAD), making cooperative security frameworks critical. The Colombo Security Conclave (CSC) emerges as a promising Indo-Pacific mechanism addressing shared non-traditional maritime threats.
CSC as a Template for Indian Ocean Security Cooperation
- A regionalised, issue-specific security architecture: CSC’s focus on maritime security, counterterrorism, cyber security, and trafficking aligns with the IMO’s assessment that coastal nations face interconnected non-traditional threats such as Illegal, Unreported and Unregulated (IUU) fishing, piracy, and narcotics flows. Its NSA-level mechanism ensures political oversight.
- Expanding membership and convergence: From a 2011 trilateral initiative (India-Sri Lanka-Maldives) to its evolution into a five-member grouping (India, Sri Lanka, Maldives, Mauritius, Bangladesh) plus Seychelles, CSC reflects rising willingness for functional cooperation in the Indian Ocean. The admission of Malaysia as a guest signals its potential Indo-Pacific outreach.
- Alignment with India’s ‘Security and Growth for All in the Region’ (SAGAR): CSC operationalises SAGAR’s principles by focusing on capacity-building, white-shipping agreements, joint patrols, and maritime domain awareness (MDA)—key for small littoral economies dependent on blue-economy sectors.
- Complementarity with other regional mechanisms: CSC can bridge gaps left by fragmented IOR institutions:
- IORA (economic focus)
- IAFNet, IFC-IOR, IOR Information Fusion Center (information-sharing)
- QUAD and AUKUS (broader strategic groupings) CSC’s niche in operational cooperation fills a structural void.
- Addressing growing China presence in the Indian Ocean: CSC offers a platform to discuss dual-use infrastructure, PLA Navy’s deployment, string-of-pearls strategy, and port-led dependencies, without direct militarisation.
Challenges Hindering Deeper Engagement
- Divergent threat perceptions (China factor): India views expanding Chinese naval activity—from Hambantota to Gwadar—as a strategic challenge. However, Sri Lanka, Maldives, Bangladesh, and Mauritius view China as a developmental partner, not a security threat. This asymmetry limits consensus on maritime posture, joint exercises, and strategic messaging.
- Weak institutionalization: CSC currently functions through summit-level engagement. Absence of: a permanent secretariat, standard operating procedures, enforceable information-sharing protocols, reduces continuity, making cooperation personality-driven.
- Domestic political volatility: Political changes in Sri Lanka (2015–19), Maldives (2023), and Bangladesh’s current instability have historically derailed trilateral cooperation. External alignment swings—e.g., Maldives’ “India Out” campaign—affect CSC cohesion.
- Resource and capability asymmetry: Small island nations lack: coastal surveillance infrastructure, hydrographic capacities, cyber-forensics capabilities. Without sustained financing and technology-sharing by India, uneven participation persists.
- Overlapping regional architectures: Member countries already engage with: China’s Belt and Road Initiative, Japan’s Free and Open Indo-Pacific, US Indo-Pacific Strategy,
creating competing incentives and diluted commitment. - Reluctance toward security alignment: Smaller states prefer non-alignment in security affairs to protect strategic autonomy. This restricts CSC’s evolution beyond non-traditional security cooperation.
Conclusion
The ocean’s geopolitical centrality, CSC’s promise depends on institutionalisation, shared threat perception, and India-led capacity building to transform Indian Ocean cooperation into a resilient regional security architecture.
