查戈斯群岛
The sovereignty of the Chagos Archipelago in the Indian Ocean is disputed between the United Kingdom and Mauritius. In February 2019, the International Court of Justice in The Hague issued an advisory opinion stating that the UK must transfer the Chagos Archipelago to Mauritius. On 22 May 2019, the United Nations General Assembly debated and adopted a resolution that affirmed that the Chagos archipelago "forms an integral part of the territory of Mauritius." The African Union urged the United Kingdom to comply with a UN resolution calling for it to withdraw from the Chagos Islands. The UK does not recognise Mauritius' sovereignty claim over the Chagos Archipelago.
