Argentina's President Javier Milei has warned the United Kingdom that it faces a legal challenge unless the Sea Lion oilfield project off the Falkland Islands is halted.
In a blunt social‑media statement, Milei set a two‑week deadline for the Sea Lion venture—a collaboration between Israeli firm Navitas Petroleum and British company Rockhopper Exploration—to be dismantled. He accused the partnership of “illegal plunder” of Argentine resources, demanding that the licences held by the companies be surrendered.
If the deadline expires, Milei said he would instruct Argentina’s foreign ministry and legal teams to initiate international arbitration at the International Tribunal for the Law of the Sea in Hamburg. The tribunal, an independent body established under the United Nations Convention on the Law of the Sea, would adjudicate disputes over maritime boundaries and resource rights.
The move comes amid Argentina’s longstanding claim to the Falkland Islands (Las Malvinas in Spanish). After the 1982 war, the islands’ inhabitants reaffirmed their preference to remain a British overseas territory in a 2013 referendum, yet Argentine leadership continues to press for sovereignty, citing the perceived unlawful nature of the British claim.
Milei’s criticism extends to the United Nations, which he described as a “useless organization.” The British defence secretary, Wes Streeting, countered by questioning Argentina’s capacity to recover the islands by force. These competing positions have intensified diplomatic tensions, with the Sea Lion project now at the heart of the dispute.
