A sovereignty dispute emerged between Chile and Argentina following comments by Argentine Air Force Chief of Staff Gustavo Javier Valverde. Valverde claimed that Magallanes, the south, and the Drake Passage are part of Argentine sovereignty, citing the region’s strategic importance as a bioceanic link. Chilean officials responded by asserting that sovereignty over the Strait of Magellan is indisputable under the 1881 Boundary Treaty and the 1984 Treaty of Peace and Friendship. The Chilean government announced plans to issue a formal note of protest. In an attempt to de-escalate, the Argentine Foreign Ministry stated that its position is governed by the same treaties and emphasized the importance of bilateral cooperation. Following the initial diplomatic exchange, Chilean lawmakers criticized the government’s response as insufficient, with some calling for a demand that Argentina rescind a 2021 decree. Meanwhile, local leaders from Punta Arenas, Chile, and Río Gallegos, Argentina, issued a joint statement to reaffirm regional integration, noting that sovereignty disputes should be handled by national governments to avoid harming local commercial and cultural ties. In recent developments, the Chilean government, led by President José Antonio Kast, issued a formal protest regarding the remarks. Argentine Defense Minister Carlos Alberto Presti subsequently contacted his Chilean counterpart, Fernando Barros, to clarify the situation. Presti characterized Valverde’s comments as the result of “confusion and sloppiness,” affirming that the Argentine government respects existing treaties and recognizes Chilean sovereignty over the strait.
