In November 1965, the UK purchased the entire Chagos Archipelago from the then self governing colony of Mauritius for £3 million to create the British Indian Ocean Territory (BIOT), with the intent of ultimately closing the plantations to provide the uninhabited British territory from which the U.S. would conduct its military activities in the region. On 30 December 1966, the U.S. and the UK executed an Agreement through an Exchange of Notes which permit the United States Armed Forces to use any island of the BIOT for defense purposes for 50 years (through December 2016), followed by a 20-year optional extension (to 2036) to which both parties must agree by December 2014. As of 2010, only the atoll of Diego Garcia has been transformed into a military facility. The indigenous populations of the islands were relocated to Mauritius and the Seychelles to make way for a joint United States-United Kingdom military base on Diego Garcia.
There are two transnational political issues which affect the status of the Chagos archipelago. First, the island nation of Mauritius claims the Chagos Archipelago (which is coterminous with the BIOT), including Diego Garcia. A subsidiary issue is the Mauritian opposition to the 1 April 2010 UK Government’s declaration that the BIOT is a Marine Protected Area with fishing and extractive industry (including oil and gas exploration) prohibited.
Second, the issue of compensation and repatriation of the former inhabitants of several of the archipelago’s atolls, exiled since 1973, continues in litigation and as of 23 August 2010 has been submitted to the European Court of Human Rights by a group of former residents.Litigation continues as of 2012 regarding the right of return for the displaced islanders and Mauritian sovereignty claims. In addition, advocacy on the Chagossians’ behalf continues both in the United States and in Europe. According to a document released by wikileaks the marine protected area in the Chagos archipelago was established to prevent former inhabitants “to pursue their claim for resettlement on the islands.”
