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