UK Delegation Visits Mauritius to Boost Chagos Maritime Security

A British delegation has travelled to Mauritius to discuss ways of reinforcing maritime security in the Indian Ocean, with the Chagos Islands at the centre of the talks. The visit signals that despite ongoing diplomatic negotiations over sovereignty of the archipelago, practical security cooperation between the two countries continues to move forward. **Background: What is the Chagos dispute?** The Chagos Islands — officially known as the British Indian Ocean Territory (BIOT) — are an archipelago in the central Indian Ocean, roughly 2,200 kilometres north-east of Mauritius. The islands have been under British control since 1965, but Mauritius has long claimed sovereignty over them, arguing their detachment from Mauritian territory before independence was illegal under international law. The archipelago is home to Diego Garcia, one of the world's most strategically significant military bases, jointly operated by the United States and the United Kingdom. This makes any sovereignty agreement enormously complex — not just for the UK and Mauritius, but for Washington as well. In 2024, the UK and Mauritius reached a landmark agreement in principle to transfer sovereignty of the Chagos Islands to Mauritius, while allowing the Diego Garcia base to continue operating under a long-term lease. However, the deal has faced political turbulence in the UK and scrutiny from the United States, meaning final ratification remains pending. **Why is maritime security on the agenda?** The Indian Ocean is one of the world's busiest and most strategically sensitive maritime corridors, linking Asia, Africa, and the Middle East. It is a critical route for global energy supplies and trade. The region has also seen rising concerns over illegal fishing, drug trafficking — the Chagos zone has been used as a transit point for narcotics destined for Southern Africa and Europe — as well as broader geopolitical competition involving China. For Mauritius, strengthening its maritime surveillance and enforcement capacity is both a security and an economic priority. The country's Exclusive Economic Zone (EEZ) is one of the largest in the world relative to its land area, covering approximately 2.3 million square kilometres. **What this means** The arrival of a British delegation focused on maritime security suggests that the two governments are keen to demonstrate tangible progress in their relationship, even as the broader sovereignty deal awaits finalisation. For Mauritius, enhanced cooperation with the UK in patrolling and securing these waters would be a significant practical benefit — and could help build the institutional framework needed if and when sovereignty is formally transferred. It also sends a message that maritime stability in the Indian Ocean remains a shared priority, regardless of where the political negotiations currently stand. For ordinary Mauritians, the Chagos question carries deep historical and emotional weight — tied to the forced displacement of the Chagossian people from the islands in the 1960s and 1970s, many of whom still live in Mauritius today and continue to seek the right of return.
