Argentine Antarctica mainland. Argentina was the only nation to have an Antarctic base for 40 years until the British built a base on the same islands. Argentina bases its claims on this sector of Antarctica on the following grounds: Argentina's claim to the Antarctic Peninsula overlaps with the Antarctic claims of Chile, 53°W to 90°W, and the UK claims, 20°W to 80°W. Currently, there are no attempts by Argentina or any other country to enforce territorial claims in Antarctica. See List of Antarctic territorial claims. None of these claims have international recognition and have been suspended by the Antarctic Treaty in 1961.
