UK Pledges to Work With Mauritius and US on Diego Garcia Path Forward

The United Kingdom has pledged to work jointly with Mauritius and the United States to find "a way forward" on the future of Diego Garcia — the strategically vital island at the centre of a long-running sovereignty dispute between London and Port Louis. The commitment from London marks the latest development in one of the most geopolitically sensitive territorial negotiations in the Indian Ocean region, involving three countries with deeply different interests in the outcome. **Background: Why Diego Garcia Matters** Diego Garcia is the largest island of the Chagos Archipelago, located roughly 1,800 kilometres south of India in the Indian Ocean. It hosts one of the most important joint US-UK military bases in the world — used for operations across the Middle East, Africa, and Asia. The base has been there since the 1960s, when the UK separated the Chagos Islands from Mauritius before granting Mauritius independence in 1968 and expelled the indigenous Chagossian population. Mauritius has long maintained that the Chagos Islands — including Diego Garcia — are rightfully part of its territory under international law. In 2019, the International Court of Justice issued a non-binding advisory opinion stating that the UK's administration of the islands was unlawful and that the decolonisation of Mauritius had not been completed lawfully. **Where Negotiations Stand** In October 2024, the UK and Mauritius announced a landmark agreement in principle under which the UK would cede sovereignty of the Chagos Islands to Mauritius, while retaining the right to operate the Diego Garcia military base under a long-term lease arrangement. The deal was widely seen as a historic breakthrough. However, the agreement stalled after the United States — under the returning Trump administration — raised concerns about the arrangement, particularly regarding security guarantees over Diego Garcia. Washington plays a central role because the base is jointly operated and critical to US military projection in the Indo-Pacific and beyond. London's latest statement signals that the UK is not abandoning the process, but that any resolution must now explicitly involve Washington as a key party — a shift in the diplomatic architecture of the talks. **What This Means** For Mauritius, the UK's renewed commitment is a positive signal that the 2024 deal is not dead. However, bringing the United States formally into the framework adds complexity. The Trump administration has shown less enthusiasm for the agreement than its predecessor, and US strategic priorities around Diego Garcia — particularly amid rising tensions with China in the Indian Ocean — mean Washington will likely seek stronger security guarantees before any sovereignty transfer is finalised. For Chagossians — many of whom live in Mauritius, the UK, and the Seychelles — the outcome of these talks will determine whether they can ever return to their homeland. Any final agreement is expected to include provisions on resettlement rights, though details remain unresolved. The three-way framework now being signalled by London suggests the road to a final agreement may be longer and more complex than originally anticipated — but the dialogue, at least, remains open.
