Bioceanic principle
The bioceanic principle (in Spanish: principio bioceánico), also called the Atlantic-Pacific principle (in Spanish: principio Atlántico-Pacífico), is a criterion or doctrine of territorial division that Argentina tried to apply as a principle of international law within its limits with Chile, of which Chile strictly rejected its existence. The difference between the two countries was the subject of diplomatic disagreements during most of the second half of the 20th century.
