Sovereignty over the Chagos Archipelago is disputed between Mauritius and the United Kingdom. Mauritius has repeatedly asserted that the Chagos Archipelago is part of its territory and that the United Kingdom (UK) claim is a violation of United Nations resolutions banning the dismemberment of colonial territories before independence. The UK has stated that it has no doubt about its sovereignty over the Chagos, and has also said that the Chagos will be returned to Mauritius once the islands are no longer required for defence purposes. Given the absence of any progress with the UK, Mauritius has decided to "internationalise" the dispute and take up the matter at all appropriate legal and political forums. The African Union and the Non-Aligned Movement have expressed unanimous support for Mauritius on the Chagos issue.
