Background | Established as a territory of the UK in 1965, a number of the British Indian Ocean Territory (BIOT) islands were transferred to the Seychelles when it attained independence in 1976. Subsequently, BIOT has consisted only of the six main island groups comprising the Chagos Archipelago. The largest and most southerly of the islands, Diego Garcia, contains a joint UK-US naval support facility. All of the remaining islands are uninhabited. Former agricultural workers, earlier residents in the islands, were relocated primarily to Mauritius but also to the Seychelles, between 1967 and 1973. In 2000, a British High Court ruling invalidated the local immigration order which had excluded them from the archipelago, but upheld the special military status of Diego Garcia. | First explored by the French in 1776, the island came under the jurisdiction of Reunion in 1814. At present, it serves as a sea turtle sanctuary and is the site of an important meteorological station. |

Disputes - international | Mauritius and Seychelles claim the Chagos Archipelago and its former inhabitants, who reside chiefly in Mauritius, but in 2001 were granted UK citizenship and the right to repatriation since eviction in 1965; repatriation is complicated by the US military lease of Diego Garcia, the largest island in the chain | claimed by Mauritius |
Economy - overview | All economic activity is concentrated on the largest island of Diego Garcia, where joint UK-US defense facilities are located. Construction projects and various services needed to support the military installations are done by military and contract employees from the UK, Mauritius, the Philippines, and the US. There are no industrial or agricultural activities on the islands. When the Ilois return, they plan to reestablish sugarcane production and fishing. | no economic activity |
