Chagos Island dispute remains unresolved after years of international debate

US and UK Agree on Sovereignty of Chagos Islands, but Crimes Against Humanity Remain Unaddressed

A recent agreement between the UK and Mauritius on the sovereignty of the Chagos Islands has brought renewed attention to the remote archipelago. The deal, which was finalized last year, transferred sovereignty to Mauritius but did not resolve ongoing issues related to US and UK responsibility for crimes against the Indigenous people of the islands, known as the Chagossians.

The Chagossians, who are largely descended from formerly enslaved East Africans, were forcibly removed from their homeland in the 1960s by US officials and the UK colonial power. The US had deemed the islanders a problem due to their presence, and they were subjected to a campaign of intimidation and deception to force them off the islands.

Between 1967 and 1973, the UK forcibly relocated over 2,000 Chagossians from all the islands, including Diego Garcia. The US built and has operated the Diego Garcia base for over 50 years, despite ongoing efforts by the Chagossians to return home.

In 2023, Human Rights Watch found that the UK and US were responsible for crimes against humanity and had a duty to provide reparations. In response, the US State Department acknowledged “regret” for the treatment of the Chagossians. However, the agreement reached between the UK and Mauritius does not address the ongoing issues faced by the Chagossians.

The treaty provides for historical recognition of wrongs but does not guarantee the return of the islands to their rightful owners. The US military base on Diego Garcia will remain in operation, despite some Chagossians hoping to work there. The agreement’s terms also suggest that the US has been influencing the negotiations behind the scenes.

The treatment of the Chagossians remains a contentious issue, with many still living in exile and facing poverty and human rights abuses. The US has yet to provide concrete assurances for the Chagossians’ return to Diego Garcia or ensure their access to reparations.
