After decades of contentious negotiations and international legal battles, the United Kingdom has agreed to return the Chagos Islands to Mauritius, marking a significant milestone in a geopolitical dispute that has lasted for over half a century. The decision follows years of mounting pressure from the United Nations (UN), international courts, and global human rights organizations, all of which have condemned the UK’s control of the archipelago as an illegal colonial holdover.
Background of the Chagos Islands Dispute
The Chagos Archipelago, a group of over 60 tropical islands in the Indian Ocean, has been at the heart of a bitter dispute between the UK and Mauritius since the 1960s. At the time, the UK forcibly removed the Chagossian population to establish a military base on Diego Garcia, the largest island in the archipelago. The base, which remains operational to this day, was leased to the United States and is considered a critical strategic asset in the region.
In 1965, three years before Mauritius gained independence from the UK, Britain separated the Chagos Islands from Mauritius, creating the British Indian Ocean Territory (BIOT). The UK justified the move by citing the strategic importance of Diego Garcia during the Cold War, but Mauritius and the displaced Chagossians have always maintained that the separation was illegal.
The plight of the Chagossian people, who were forcibly displaced to Mauritius and Seychelles, has been a long-standing humanitarian issue. Many have lived in poverty and struggled for recognition and the right to return to their homeland. Over the years, various legal actions have been taken by Chagossians seeking compensation and the right to return, but until now, the UK had maintained control over the islands.
Key Turning Points in the Dispute
The UK’s decision to return the islands comes after several important rulings and international statements. In 2019, the International Court of Justice (ICJ) delivered an advisory opinion declaring that the UK’s administration of the Chagos Islands was illegal and that the islands should be returned to Mauritius as soon as possible. The ICJ ruling was followed by a resolution in the UN General Assembly, where the majority of member states voted in favor of Mauritius’s claim to sovereignty over the archipelago. Despite these rulings, the UK initially refused to comply, citing the strategic importance of the Diego Garcia military base.
Pressure on the UK increased in 2021 when the UN’s International Tribunal for the Law of the Sea ruled that Mauritius had sovereignty over the Chagos Islands, further undermining Britain’s legal position. These developments led to renewed negotiations between the UK and Mauritius, culminating in the October 2024 agreement.
The 2024 Agreement: Terms and Conditions
On October 3, 2024, both the UK and Mauritius issued a joint statement confirming the agreement to transfer sovereignty over the Chagos Islands to Mauritius. The statement emphasized the two countries’ commitment to a peaceful and orderly transition, ensuring that the strategic and security interests of both nations, as well as those of the United States, are preserved. The military base on Diego Garcia will remain operational under the terms of the existing lease with the US, but it will now be subject to oversight from the Mauritian government .
In the joint statement, UK Foreign Secretary James Cleverly acknowledged the historical injustices suffered by the Chagossian people and expressed the UK’s commitment to supporting their right to return. The statement also indicated that both countries would work together to develop a comprehensive plan for the resettlement of the Chagossians on their ancestral lands.
Mauritius Prime Minister Pravind Jugnauth welcomed the agreement, calling it a “historic moment for the people of Mauritius and the Chagossian community.” He further emphasized that the return of the islands is not only a matter of territorial integrity but also an issue of justice for the thousands of Chagossians who were forcibly removed from their homes.
Impact on Chagossians: A Long-Awaited Victory
For the Chagossian people, the return of the islands represents a long-awaited victory in their decades-long struggle for justice. Since their forced displacement in the late 1960s and early 1970s, the Chagossians have faced numerous legal obstacles in their quest to return to their homeland. Many have lived in exile in Mauritius, Seychelles, and the UK, often in poor conditions.
Chagossian groups have welcomed the 2024 agreement but are urging both governments to act swiftly to ensure their right to return is implemented without delay. Olivier Bancoult, the leader of the Chagos Refugee Group, expressed hope that the agreement would lead to concrete actions, including the resettlement of Chagossians on the islands and compensation for the hardships they endured over the years.
The UK government has pledged to provide financial assistance to facilitate the resettlement of Chagossians and improve infrastructure on the islands, ensuring that those who choose to return can do so in dignified and sustainable conditions. However, some experts have raised concerns about the logistical challenges of resettling a population on islands that have been largely uninhabited for decades. The islands’ infrastructure is underdeveloped, and environmental issues, such as rising sea levels, could pose additional challenges for resettlement efforts .
Geopolitical Implications: Diego Garcia and Strategic Interests
One of the key factors in the Chagos dispute has always been the Diego Garcia military base. Located in the center of the Indian Ocean, the base has played a crucial role in US military operations, particularly in the Middle East and South Asia. The base is home to several thousand US military personnel and contractors and has been used for missions ranging from counterterrorism operations to logistical support for the Afghanistan and Iraq wars.
Under the terms of the 2024 agreement, Diego Garcia will remain under the control of the US military for the foreseeable future. However, the base will now operate under Mauritian sovereignty, with Mauritius assuming a more prominent role in overseeing the base’s activities. This arrangement is likely to preserve the strategic interests of all parties involved, including the US, which relies heavily on Diego Garcia for its Indian Ocean operations.
The UK and Mauritius have both stressed that the agreement will not impact the military’s strategic importance, and all three countries will continue to cooperate closely on security and defense matters. However, some analysts have suggested that the transfer of sovereignty could lead to increased scrutiny of US military operations on Diego Garcia, particularly with regard to environmental issues and human rights concerns.
A New Chapter for Mauritius and the Chagos Islands
The agreement to return the Chagos Islands to Mauritius marks a significant turning point in the long-running dispute between the UK and Mauritius. It is not only a victory for Mauritian sovereignty but also a moment of justice for the displaced Chagossian community, who have fought tirelessly for their right to return home.
While many challenges remain—particularly in terms of resettling the Chagossian population and managing the geopolitical complexities surrounding Diego Garcia—the 2024 agreement represents a crucial step forward. Both the UK and Mauritius have expressed their commitment to a peaceful and collaborative transition, and with the support of the international community, the future of the Chagos Islands now appears brighter than it has in decades.
For Mauritius, the return of the islands is a matter of national pride and territorial integrity, while for the Chagossians, it is a long-overdue acknowledgment of the injustices they have endured. As the UK prepares to hand over sovereignty, the world will be watching closely to see how this new chapter in the history of the Chagos Islands unfolds.
