Trump Critiques UK’s Chagos Islands Agreement with Mauritius
Donald Trump has sharply criticised the United Kingdom’s decision to transfer sovereignty of the Chagos Islands to Mauritius, which includes the formal handover of Diego Garcia, a critical site for a US military installation. The former US president denounced the move as “an act of great stupidity,” claiming that the UK acted without justification.
Meanwhile, the UK government is defending its stance, stating that the decision was made to safeguard its military interests amid legal challenges that could jeopardise operations at the Diego Garcia base. An official government representative asserted on January 20 that the UK would not compromise on national security.
Current Status of the Deal
While the UK and Mauritius have reached an agreement, it has yet to be ratified by the UK Parliament, meaning the islands remain under British jurisdiction for now.
Background on the Chagos Islands
The Chagos Islands are a group of over 600 islands situated in the Indian Ocean, equidistant between Africa and Indonesia, with around 4,000 people currently residing there. The UK annexed the islands in the early 19th century, retaining control even after Mauritius gained independence in 1968. In the 1970s, Britain expelled nearly 2,000 indigenous inhabitants, known as Chagossians, to facilitate the establishment of a US military base on Diego Garcia.
This episode is viewed as one of the more regrettable chapters in contemporary British colonial history, as Chagossians have fought for decades for the right to return to their homeland.
The Importance of Diego Garcia
Diego Garcia is a pivotal military base for both the UK and the US, leased to the latter but operating as a joint facility since 1971. Its strategic location is considered vital for military operations in the Indian Ocean and areas beyond, providing a unique platform for UK and US forces in the Middle East, the Indo-Pacific, and Africa.
Notably, the base has played a significant role in military operations, including deployments against terrorist groups in Iraq and Afghanistan, and more recent strikes on Houthi targets in Yemen.
Negotiations and Controversy
Mauritius has contested UK sovereignty over the islands for over 50 years, leading to legal proceedings initiated in 2010. This resulted in the UK’s agreement to negotiate sovereignty transfer in 2022, though discussions faced interruptions due to warnings that ceding the islands would represent a “major self-inflicted blow.” In October 2024, an agreement was finally reached between the UK and Mauritius, although it received backlash from some UK lawmakers and local Britons.
In a more conciliatory tone, leaders from Canada, Australia, and India expressed their support for this agreement, as did Trump in early 2025.
Contents of the Final Deal
Upon signing the deal, the UK government outlined several key stipulations:
- The UK will relinquish sovereignty over the Chagos Islands while leasing the Diego Garcia base from Mauritius for a period of 99 years.
- Access to the islands surrounding Diego Garcia is restricted for other nations without the UK’s consent.
- Resettlement of Chagossians is permitted on all islands except Diego Garcia.
- The agreement can be extended for an additional 40 years upon mutual agreement.
- The estimated financial implications could reach up to £30 billion, with an average annual cost of £101 million.
- Both the UK House of Commons and Mauritius Parliament need to ratify the final agreement.
Concerns Surrounding the Agreement
Some apprehensions about the deal focus on the unpredictability of future Mauritian governments adhering to the agreement, potentially allowing countries like China, which has invested heavily in Mauritius, to establish military presence in the region. US officials have echoed similar concerns regarding national security implications. Additionally, criticisms emerged from some Chagossians who felt excluded from the decision-making process, and the House of Lords has questioned aspects of the deal, particularly concerning financial transparency and operational arrangements for Diego Garcia.
This agreement marks a significant moment in UK-Mauritius relations and raises critical questions about the evolving dynamics of military sovereignty and diplomatic ties in the Indian Ocean region.
