The Indian Ocean has emerged as a focal point of intensifying geopolitical competition, prompting renewed calls for the establishment of an Indian Ocean Zone of Peace (IOZP). While the concept of a demilitarized zone in the region dates back to a 1971 United Nations General Assembly declaration, modern security analysts argue that the current escalation of naval activity and the presence of external military powers necessitate a fundamental rethink of regional stability.
The Origins and Evolution of the IOZP
The Indian Ocean Zone of Peace was first proposed in 1971, championed by Sri Lanka under the leadership of Sirimavo Bandaranaike. According to the United Nations Office for Disarmament Affairs, the initiative aimed to eliminate great-power military presence and nuclear weapons from the region to ensure the sovereignty and territorial integrity of littoral states.

Despite the initial momentum, the IOZP has largely remained an unrealized objective. The S. Rajaratnam School of International Studies (RSIS) notes that the Indian Ocean has instead become a theater for power projection, characterized by increased naval maneuvers, the expansion of overseas military bases, and heightened tensions between major global actors, including the United States, China, and regional powers.
Geopolitical Challenges to Regional Security
The security landscape in the Indian Ocean is currently defined by a "security dilemma," where defensive actions by one state are perceived as threats by others. Research from the Council on Foreign Relations highlights that the strategic importance of maritime trade routes, such as the Strait of Malacca, has incentivized states to increase their naval footprint.
Unlike other regions that have established formal security dialogues, the Indian Ocean lacks a singular, binding mechanism to manage maritime disputes. This gap has led to calls for a new approach that incorporates modern environmental and technological security concerns, such as the ENMOD Convention, which prohibits the military or other hostile use of environmental modification techniques.
Priorities for the Next UN Secretary-General
As the United Nations prepares for future leadership transitions, diplomats have suggested that the Indian Ocean should be a priority for the next Secretary-General. The United Nations charter emphasizes the peaceful settlement of disputes, yet the Indian Ocean remains a glaring omission in many high-level security agendas.
Experts suggest that a modern IOZP framework must go beyond the original 1971 parameters to include:
- Maritime Domain Awareness: Enhanced cooperation between coastal states to combat piracy, illegal fishing, and human trafficking.
- Environmental Security: Addressing the impact of climate change on small island developing states (SIDS), which are disproportionately affected by rising sea levels in the Indian Ocean.
- Arms Control: Developing transparency measures to prevent an unchecked naval arms race.
Comparison: 1971 vs. 2024
The context surrounding the IOZP has shifted significantly over the last five decades.

| Feature | 1971 Context | 2024 Context |
|---|---|---|
| Primary Actors | Cold War Superpowers | Multi-polar regional and global powers |
| Focus | Decolonization and Neutrality | Trade security and technological dominance |
| Security Scope | Conventional Military Presence | Cyber, environmental, and maritime security |
Future Outlook
The legacy of Sirimavo Bandaranaike’s push for a peace zone continues to serve as a reference point for diplomats seeking to de-escalate regional tensions. However, the path forward requires reconciling the strategic interests of major powers with the security needs of the Indian Ocean littoral nations. Whether the international community can effectively modernize the IOZP remains a central question for future multilateral security discussions.
