About Colombo Security Conclave

• The Colombo Security Conclave (CSC) is a regional security grouping formed to promote closer cooperation among member states on critical security issues and to enhance regional security in the Indian Ocean Region.
• Initially known as the Trilateral for Maritime Security Cooperation, it started in 2011 among India, Maldives, and Sri Lanka.
• Over time, it expanded to include Mauritius (2022), Bangladesh (2024), and Seychelles as an observer state. Malaysia has also participated as a guest.

The CSC focuses on cooperation under five key pillars

• Maritime Safety and Security
• Countering Terrorism and Radicalization
• Combating Trafficking and Transnational Organized Crime
• Cybersecurity and Protection of Critical Infrastructure and Technology
• Humanitarian Assistance and Disaster Relief

This expansion underscores CSC's growing importance as a platform for regional trust-building, joint exercises, information sharing, and capacity building to address emerging security challenges in the Indian Ocean Region.
