President Javier Milei plans to announce a new law on Thursday, March 3, during a national broadcast addressing the sovereignty claim over the Malvinas islands. ^[1] Argentine President Javier Milei announced on Thursday that he plans to strengthen sanctions against oil companies operating in waters near the disputed Falkland Islands. ^[2] President Javier Milei stated that Argentina will construct a naval base in Tierra del Fuego, a province within whose territory Argentina considers the Falkland Islands to be located. ^[3] Argentine President Javier Milei announced on Thursday night a series of diplomatic, economic, and legal measures to reinforce the country's sovereignty claim over the Falkland Islands. ^[4] Argentina's Foreign Minister Pablo Quirno warned that companies extracting resources in the disputed Falkland Islands must choose between continuing illegal operations or facing sanctions that would bar them from operating in Argentina. ^[5] Mark Stone emphasized that Argentina has never had sovereignty over the Falklands and that the British claim predates the creation of Argentina. ^[6] Argentine President Javier Milei announced on 2026-04-12 that the nation will deploy diplomatic, economic, judicial, and legal tools to deter actors involved in the Sea Lion oil project in the Falkland Islands. ^[7] The measure is linked to the advancement of natural resource exploitation projects in the South Atlantic, specifically the Sea Lion project led by the British firm Rockhopper Exploration and the Israeli firm Navitas Petroleum. ^[8] The proposed law aims to sanction Argentine companies that provide services, assistance, or logistical support to foreign companies developing economic activities in the islands without Argentine authorization. ^[9] The White House intends to keep diplomatic channels open with the United Kingdom to eventually sit down and discuss the sovereignty issue, despite the new pressure. ^[10] Milei announced that he would send a legislative project to the Argentine Congress to increase punishments for companies operating near the islands. ^[11] Milei described the Sea Lion project, led by British firm Rockhopper Exploration and Israeli firm Navitas Petroleum, as an urgent threat to Argentina's national cause. ^[12]
