Strait of Magellan sovereignty dispute defused by Argentina and Chile

Strait of Magellan sovereignty dispute diplomatic tension Argentina-Chile relations Magallanes region

A diplomatic tension between Argentina and Chile regarding the sovereignty of the Strait of Magellan has been defused following direct communication between defense ministers. The controversy began after Brigadier General Gustavo Javier Valverde, Chief of the General Staff of the Argentine Air Force, suggested in a podcast interview that Argentina should reinforce its presence in the Strait and the Drake Passage, describing them as a “bioceanic key.”

Chilean authorities responded with a formal protest, asserting that the Strait is entirely Chilean under the 1881 and 1984 treaties. In response, Argentine Defense Minister Carlos Presti held a telephone call with his Chilean counterpart, Fernando Barros, to clarify the situation. Presti attributed Valverde’s remarks to “confusion and lack of care,” stating that the Argentine government does not dispute Chilean sovereignty over the area.

Local leaders in the border cities of Río Gallegos and Punta Arenas issued a joint statement expressing concern over the remarks, emphasizing that sovereignty issues must be handled through national diplomacy to preserve regional integration. Meanwhile, some Chilean legislators criticized the government's response as insufficient, calling for a firmer stance. President José Antonio Kast is scheduled to visit the Magallanes region to observe ongoing military exercises in the area.
