Argentine President Javier Milei vowed on Thursday to recover the Falkland Islands and tighten sanctions on oil firms operating in the disputed territory, escalating tensions with Britain and signaling a more aggressive stance after months of diplomatic rhetoric.
In a televised national address, Milei announced he would send Congress an urgent bill to strengthen penalties against companies involved in oil exploration around the islands, including the Sea Lion oilfield expected to begin production in 2028. He said he would also extend sanctions to suppliers, shareholders, and directors of firms operating in the territory.
The Sea Lion project, operated by Israeli firm Navitas Petroleum and British company Rockhopper Exploration, sits roughly 140 kilometers north of the Falklands and contains an estimated 1.7 billion barrels of oil. Milei called the oilfield a “clear and present danger” to Argentine interests, warning that if Argentina did not act quickly, the companies would soon have “the material capacity to access the oil that lies underneath our sea.”
Milei’s announcement came days after U.S. President Donald Trump said he was reviewing America’s position on the Falklands, departing from decades of official U.S. neutrality. Trump told GB News on Thursday that he was uncertain whether Britain had “the capacity” to defend the islands, citing Britain’s reduced global power compared to 25 years ago. Trump also suggested the U.S. might use the Falklands issue as leverage to pressure Britain over defense spending and its stance on the Iran war.
Britain has controlled the islands since 1833 and has consistently maintained that the Falkland Islanders themselves should determine the territory’s future. A 2013 referendum showed 99.8 percent of residents voted to remain a British overseas territory. British Defence Secretary Wes Streeting said Friday that the UK’s commitment to the Falklands is “absolute and unshakeable,” adding that Milei’s statement “tells us more about domestic politics in Argentina than it does about the Falkland Islands.”
Argentina has claimed the islands since its independence from Spain in the early 19th century, calling them Las Malvinas. The two nations fought a 74-day war over the territory in 1982, which Britain won after dispatching a naval task force to the South Atlantic. The conflict killed 255 British military personnel, three islanders, and 649 Argentine soldiers.
A current Argentine law already permits restrictions on oil companies operating in projects deemed unauthorized on the islands, but Milei’s bill would expand the framework and accelerate enforcement. The move reflects both regional geopolitical shifts and domestic political pressure: Milei’s approval rating has fallen to around 34 percent, and he faces a presidential election within a year against Vice President Victoria Villarruel, a pro-military politician who has criticized his diplomatic approach to the Falklands dispute.
Rockhopper’s stock fell 8 percent on Friday following Milei’s address. The BBC contacted both Rockhopper and Navitas Petroleum for comment but neither firm responded immediately. Downing Street reiterated that the Falkland Islanders have a right to “exploit their own natural resources” and that the territory will remain British “for as long as the Islanders wish.”
