France Approves Treaty Defining Saint-Martin Border

On July 16, 2026, France's National Assembly approved legislation to formally define the border between the French and Dutch sides of the Caribbean island of Saint-Martin, nearly four centuries after the initial division.

Historical Context

The division of Saint-Martin dates back to 1648, when France and the Netherlands agreed to split the island. However, the exact border was never precisely defined, leading to recurring disputes over permits, law enforcement, and environmental management, particularly around the island's lagoon.

Details of the Treaty

The newly approved treaty, signed in 2023, aims to provide legal certainty for the open frontier between Saint-Martin, a French overseas collectivity and part of the European Union, and Sint Maarten, a self-governing country within the Kingdom of the Netherlands that lies outside the EU. Residents have historically crossed freely between the two sides despite differences in customs, immigration, and tax systems.

Implications and Next Steps

This agreement is expected to resolve longstanding disputes and enhance cooperation between the two territories. The Kingdom of the Netherlands must still ratify the agreement before it can enter into force.
