evidence: Tromelin Island (/ˌtroʊmlɪn/[citation needed]; French: Île Tromelin, pronounced [il tʁɔmlɛ̃]), once called the Isle of Sand, is a low, flat island in the Indian Ocean about 500 km (310 mi; 270 nmi) north of Réunion and about 450 km (280 mi; 240 nmi) east of Madagascar. Tromelin is part of the Scattered Islands in the Indian Ocean, the fifth district of the French Southern and Antarctic Lands, a French Overseas Territory, but Mauritius claims sovereignty over the island. [...] Tromelin is administered as part of the French Southern and Antarctic Lands, a French Overseas Territory, but Mauritius claims sovereignty over the island despite its absence in the listing of the 8th article of the 1814 Treaty of Paris.[19] Indeed, the treaty does not specifically mention all the dependencies of Mauritius, which leads to uncertainty on the sovereignty of Tromelin, and the official text was that written in French. During the British period of Mauritius, France administered the island as a dependency of the region of Réunion and built infrastructure without British protest. France and Mauritius have been negotiating for years in regard to the possible establishment of a condominium over the island. In 2010, Mauritius and France reached an agreement on the co-management of Tromelin, without prejudice to the sovereignty of Mauritius over Tromelin.
