Representatives from Mexico, the US and Cuba met in Mexico City in a continuing effort to delineate each country’s rights in a disputed area of the Gulf of Mexico, according to Reuters.
This is the second time this year that the three countries have had talks about the so-called Western Polygon, an oil and gas rich area, parts of which fall into overlapping areas of influence.
The previous talks were in July.
Under international law all three nations can claim the same part because it is within 200 miles of their shores.
This area in the Western Polygon where the countries share a claim is nicknamed the “Doughnut Hole”.
Interest in the “Doughnut Hole” has picked up ever since late 2014 when the US and Cuba announced they would restore diplomatic ties.
