The move followed a formal protest from Chile regarding remarks made by the head of the Argentine Air Force General Staff, Brigadier General Gustavo Javier Valverde. In a Sunday interview, Valverde described the Strait of Magellan and the Drake Passage as a "bioceanic key" where Argentina must maintain a presence, prompting concerns from Chilean authorities.
Diplomatic Tensions Over Sovereignty
During an interview with the YouTube channel La Fábrica del Podcast, General Valverde stated that the southern region and the Drake Passage were matters of sovereignty. While he did not explicitly name a country, Chilean officials interpreted the comments as a challenge to their sovereignty over the Strait of Magellan. Chilean Foreign Minister Francisco Pérez Mackenna, speaking from Vietnam, called the country's sovereignty over the strait "indisputable" and urged foreign officials to exercise responsibility in their public statements.
Treaty Framework and Cooperation
The Argentine foreign ministry's statement, released under the ministry headed by Pablo Quirno, clarified that the 1881 and 1984 treaties remain fully in force and definitive. The 1881 treaty established Chilean sovereignty over the strait and guaranteed free navigation for all nations, while the 1984 treaty, mediated by the Holy See, settled boundary disputes following the 1978 Beagle Channel crisis. Argentina emphasized the strategic value of its cooperation with Chile, citing joint Antarctic naval patrols and shared interests in marine protection.
