Chilean President José Antonio Kast will lead a military review of the Chilean Navy's Task Force in Magallanes on Wednesday, including tactical maneuvers, anti-submarine exercises, boarding operations, and live fire in the southern waters of the country. ^[1] Chilean President José Antonio Kast led a major military deployment in the Magallanes region on Wednesday, overseeing naval exercises designed to test the Chilean Armed Forces' response capabilities. ^[2] Defense Minister Fernando Barros stated in an interview with Radio Duna that the situation is close to resolution, noting that Argentina has a new text ready for President Milei's signature and that Argentine authorities acknowledged the previous statements were due to an error or confusion. ^[3] In March 2025, President Javier Milei formally committed to modifying the decree after recognizing it contained an 'error of interpretation' regarding bilateral agreements, though the norm remains in force. ^[4] The dispute originates from Argentine Decree 457/2021, signed during the Alberto Fernández administration, which defines the Strait of Magallanes and the Drake Passage as 'shared space' requiring joint exploration and control. ^[5] President Kast participated from the frigate Capitán Prat, accompanied by Interior Minister Claudio Alvarado, Defense Minister Fernando Barros, and Chilean Navy Commander-in-Chief Admiral Fernando Cabrera. ^[6] The activities included tactical maneuvers, anti-submarine operations, boardings, ship resupply, and live-fire drills. ^[7] The maneuvers were conducted one day before President Kast was scheduled to host Argentine President Javier Milei in Santiago for a bilateral meeting. ^[8]
