On 23 March 1648, the French Kingdom and the Dutch Republic signed the Treaty of Concordia atop Mount Concordia, in which both agreed to divide the island of Saint Martin into their own territories – the French Kingdom owning the northern part of the island and the Dutch Republic owning the southern part of island.

On 17 May 1994, the French Republic and the Kingdom of the Netherlands signed the Franco-Dutch treaty on Saint Martin border controls in Paris, aimed at improving border control at the two airports on Saint Martin, namely the Princess Juliana International Airport at the Dutch Sint Maarten and the L'Espérance Airport at the French Collectivity of Saint Martin.
The treaty was ratified on 1 August 2007.
Among the provisions of the treaty is a requirement for a visa or a landing permit for both the Dutch and French sides if a foreigner is to visit the island of Saint Martin.
