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 Paris Treaty. Indeed, the treaty doesn't specifically mention all the dependencies of Mauritius which leads to uncertainty on the sovereignty of Tromelin, and the official text was the most clearly text in French. During the British period of Mauritius, France administrated 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.
