UN recognition of Mexico’s Gulf of Mexico continental shelf limits, Digi Mart USA News (Gulf of Mexico): After nearly 15 years of negotiations and technical studies, the United Nations Organization has endorsed the outer limits of Mexico’s continental shelf in the Gulf of Mexico. The Mexican Foreign Ministry (SRE) said the recognition represents an important step toward protecting the country’s natural resources.
The SRE said the recognition gives Mexico legal certainty to explore and exploit natural resources found on the seabed and in its subsoil in a region known as the Eastern Polygon of the Gulf of Mexico. The recognized zone lies more than 200 nautical miles, roughly 370 kilometers, from the Mexican coast, and its limits respect maritime boundaries previously negotiated with the United States and Cuba.
Authorities clarified that the UN decision does not mean Mexico has acquired new territory. Instead, it recognizes the limits within which Mexico may exercise exclusive sovereign rights over seabed and subsoil resources.
Mexico submitted its request to the UN Commission on the Limits of the Continental Shelf in December 2011. Since then, Mexican specialists carried out scientific, geographic and legal research to demonstrate the extent of the continental shelf.
Institutions involved in the process included the Secretariat of the Navy, INEGI, the Mexican Geological Service and Petróleos Mexicanos (Pemex).
In July 2026, the Commission approved its technical recommendations, a summary of which the United Nations published in November of this year. The Foreign Ministry explained that the next step is to officially deliver to the UN the maps and geographic data establishing the outer limits of Mexico’s continental shelf, so they can receive international publicity.
According to authorities, the recognition strengthens Mexico’s legal security over its marine resources and advances the defense of its maritime rights and interests under international law.
