Argentina-Chile border dispute

The Argentina-Chile border dispute primarily revolves around territorial claims in the southern Andes, especially in the region of Patagonia and the Andes mountains. Historically, disagreements arose from vague boundary definitions and competing national interests in resource-rich areas. Over time, negotiations and treaties, such as the 1984 Treaty of Peace and Friendship, have sought peaceful resolutions. Most of the border is now well-defined, but some areas, like the Isla Navarino and parts of Patagonia, still see minor disagreements. The conflict is managed through diplomatic dialogue and international agreements, emphasizing cooperation over dispute.
