Corsica and the French mainland form Metropolitan France; Guadeloupe, Martinique, Réunion, and Mayotte form, with French Guiana, the overseas regions. These two integral groupings, along with several overseas collectivities and one territory, comprise the French Republic. The collectivity of Saint Martin borders Sint Maarten, a constituent country of the Kingdom of the Netherlands; however, since, Saint Martin is significantly autonomous of the French government, this is not considered an international border.
