Maritime Border Treaty Between Dutch Kingdom and St. Kitts and Nevis Moves Toward Ratification After 12-Year Delay

Caribbean, The Netherlands, | By Correspondent October 20, 2026

 

THE HAGUE – A maritime boundary agreement between the Kingdom of the Netherlands and St. Kitts and Nevis could finally be ratified, more than twelve years after both sides reached an understanding on the delimitation of their territorial waters.

The agreement establishes an approximately 140-kilometer maritime boundary, including waters near Sint Eustatius, and is considered important for fisheries management, marine environmental protection and the legal administration of maritime resources.

Negotiations began in 2013 and were substantively completed in 2014. However, the formal signing of the treaty was delayed because of internal decision-making procedures in St. Kitts and Nevis.

The agreement must still receive parliamentary approval before it can be ratified and enter into force.

Clear Boundaries for Fisheries and Environmental Protection

Thittse establishment of a formally recognized maritime boundary is important for both countries because it clarifies their respective jurisdictions over surrounding waters.

For Sint Eustatius, which lies close to St. Kitts and Nevis, the agreement has particular practical significance.

Clearly defined maritime boundaries help authorities determine which country is responsible for regulating activities such as commercial fishing, protecting marine ecosystems and managing maritime resources.

They can also facilitate cooperation in addressing environmental concerns that extend beyond national borders.

The agreement provides a legal framework for managing the maritime area while reducing uncertainty about the division of jurisdiction between the two countries.

Direct Cooperation Between Sint Eustatius and St. Kitts and Nevis

An important provision of the treaty allows for local consultations between Sint Eustatius and St. Kitts and Nevis concerning the management of the maritime area.

This creates opportunities for the neighboring islands to coordinate on practical matters affecting their shared marine environment.

Such cooperation could be relevant to fisheries, environmental protection and other activities taking place near the maritime boundary.

The provision recognizes the geographical proximity of Sint Eustatius and St. Kitts and Nevis and the importance of addressing local maritime issues through direct consultation.

Provisions for Possible Oil and Gas Discoveries

The treaty also anticipates the possibility that oil or natural gas deposits could be discovered in areas extending across the maritime boundary.

If such cross-border deposits are identified in the future, the agreement provides for consultations between the parties.

This provision is intended to establish a framework for discussions about resources that may extend into the maritime jurisdictions of both countries.

It does not indicate that commercially viable oil or gas fields have been discovered in the area.

Rather, it addresses a potential future situation in which the two countries would need to coordinate their approach to shared underground resources.

Other Caribbean Maritime Boundaries Remain Unresolved

Although the agreement with St. Kitts and Nevis could now move toward ratification, the Kingdom of the Netherlands has not yet completed all its maritime boundary arrangements in the northeastern Caribbean.

Negotiations are continuing with the United Kingdom concerning the maritime boundary with Anguilla.

Discussions also remain underway with the United States regarding the delimitation of waters involving the U.S. Virgin Islands.

These outstanding negotiations form part of the broader effort to establish clear maritime jurisdictions around the Dutch Caribbean islands.

For the Kingdom, completing such agreements is important for legal certainty, maritime governance and cooperation with neighboring countries.

Parliamentary Approval Still Required

Despite the progress after more than a decade of delays, the agreement with St. Kitts and Nevis has not yet completed the ratification process.

Parliamentary approval remains necessary before the treaty can be formally ratified.

Once the required procedures have been completed, the agreement would provide a formal legal basis for the approximately 140-kilometer maritime boundary and the cooperation arrangements associated with it.

For Sint Eustatius, the treaty represents an important step toward greater clarity in the management of surrounding waters and closer coordination with its Caribbean neighbor.
