In a landmark decision, the United Kingdom has consented to transfer sovereignty of the Chagos Islands to Mauritius, concluding a prolonged dispute over the Indian Ocean archipelago. This agreement, endorsed by U.S. President Donald Trump, permits the UK to retain control over the joint U.S.-UK military base on Diego Garcia through a 99-year lease.
The Chagos Islands were separated from Mauritius by the UK in 1965, three years prior to Mauritius achieving independence. The impending handover represents a significant triumph for Mauritius, which has persistently advocated for the return of the islands, citing historical injustices and favorable international legal rulings. Mauritian Prime Minister Pravind Jugnauth has lauded the decision as a pivotal step in the nation’s decolonization process.
Financial Terms & Implications
Under the terms of the agreement, the UK will pay Mauritius £90 million annually to lease back Diego Garcia for 99 years, with an option for an additional 40 years. This financial arrangement is anticipated to bolster the Mauritian economy, facilitating investments in infrastructure, healthcare, and education.

However, the deal has faced criticism from various quarters. Senior Republicans in the U.S. have expressed concerns about Mauritius’s ties with China, fearing potential security implications for the strategically vital military base on Diego Garcia. In the UK, figures such as Nigel Farage have condemned the agreement as excessively costly, suggesting that inflation could drive total costs to exceed £50 billion.
Impact on the Chagossian Community
The agreement also acknowledges the plight of the Chagossians, thousands of whom were forcibly removed from the islands in the 1960s and 1970s to make way for the military base. While the deal includes provisions for a resettlement fund to assist displaced islanders in returning to other islands within the archipelago, resettlement on Diego Garcia remains prohibited due to its military significance.
Some Chagossians have criticized the deal for not including them in the decision-making process, expressing concerns about being sidelined in negotiations that directly affect their homeland.

The return of the Chagos Islands to Mauritius signifies a notable shift in the Indian Ocean region. It enhances Mauritius’s position in regional diplomacy and grants it greater control over maritime resources. Despite apprehensions regarding Mauritius’s relationship with China, UK officials maintain that India’s influence in the region is more substantial.
While the handover resolves a longstanding colonial dispute, Mauritius now faces the challenges of resettling the Chagossian community, balancing development with environmental conservation, and ensuring that the regained sovereignty aligns with its national interests. This agreement marks a defining moment for Mauritius, reaffirming its independence and shaping its future on the global stage.
