Argentina’s President Javier Milei has threatened legal action against the UK unless oil exploration at the Sea Lion field off the Falkland Islands is halted within two weeks. In a social media post, Milei said he had instructed Argentina’s Foreign Ministry and legal teams to pursue international arbitration, and warned that Argentina could take the dispute to the International Tribunal for the Law of the Sea. He described the project as the “illegal plundering” of Argentine resources and called its development “illegitimate exploitation.” The oilfield is a joint venture between UK-based Rockhopper Exploration and Israel’s Navitas Petroleum. The companies say they hold valid licences issued by the Falkland Islands, while Argentina disputes the work. Extraction is expected to begin within two years. Sea Lion is about 130 miles from the islands and is estimated to contain 1.7 billion barrels of oil.
The threat adds to longstanding tensions over sovereignty. Argentina calls the islands Las Malvinas, and the UK and Argentina have disputed ownership for decades. Milei recently criticised the United Nations for failing to resolve the issue, calling it “a useless organisation.” UK Defence Secretary Wes Streeting has said Argentina lacks the ability to take the islands by force. Milei has also previously called the oilfield a “clear and present danger.”
The dispute is rooted in the 1982 war, which began after Argentine forces landed on the islands to assert a territorial claim. A British task force expelled them after 74 days of fighting. The conflict killed 255 British military personnel, three islanders and 649 Argentine military personnel. In a 2013 referendum, 99.8% of Falkland Islanders who voted supported remaining a British overseas territory; only three voted against.

Argentine President Javier Milei has given the United Kingdom two weeks to halt the Sea Lion offshore oil project near the Falkland Islands, warning that Argentina will initiate international legal proceedings if work continues. Milei said Argentina would pursue arbitration and take the case to the International Tribunal for the Law of the Sea in Hamburg. Argentina contends that UK authorization of oil exploration breaches a United Nations resolution urging both sides to avoid unilateral actions while the sovereignty dispute remains unresolved.
The Sea Lion field lies about 220 kilometers north of the islands. It is being developed by Israel’s Navitas Petroleum and Britain’s Rockhopper Exploration under licenses granted by Falkland Islands authorities, with production expected to begin in 2028. The companies reject Argentina’s objections and say their licenses are valid. The UK has defended the islanders’ right to develop local natural resources.
Milei has also threatened restrictions on companies involved in what Argentina considers unauthorized exploration, potentially barring them from the country’s oil and mining industries. His government has proposed legislation that could impose prison sentences of up to 20 years for resource extraction around the islands without Argentine permission. Argentine authorities say they are investigating at least 60 companies and executives.
The dispute is rooted in competing sovereignty claims. Britain has controlled the islands since 1833, while Argentina calls them the Malvinas and claims them as its own. Argentina’s 1982 invasion led to a 10-week war that killed 649 Argentine military personnel, 255 British service members and three islanders before British forces retook the territory. The UK cites the islanders’ right to determine their future, pointing to a 2013 referendum in which 99.8% of voters supported remaining a British Overseas Territory. Argentina rejects that vote and continues to assert its claim.

Argentine President Javier Milei has threatened legal action against the United Kingdom over the Sea Lion oil project in the North Falkland Basin, roughly 220 kilometers from the Falkland Islands. Argentina claims sovereignty over the British-administered islands, known in Argentina as the Malvinas. The two countries fought a 10-week war over the territory in 1982, in which 255 British and 649 Argentine troops were killed.
Milei said he had directed Argentina’s Foreign Ministry and legal teams to begin arbitration proceedings, alleging that the project involves the illegal exploitation of Argentine resources. He warned that Argentina would take its case to the International Tribunal for the Law of the Sea if the UK did not halt what he called illegitimate exploitation within two weeks. Argentina has already pursued legal action, arguing that the project authorized by Britain contravenes a UN resolution calling on both sides to avoid unilateral actions while the sovereignty dispute remains unresolved.
Sea Lion’s developers, Israel’s Navitas and Britain’s Rockhopper, maintain that they have valid exploration licences issued by the UK. The British government has backed companies operating near the islands, saying they have the right to develop natural resources as they see fit. Argentina has renewed its sovereignty campaign after US President Donald Trump said Washington was open to reviewing its historically neutral position on the territory.
Separately, Falkland Islands business representatives arrived in Punta Arenas, Chile, to relaunch a maritime route between the ports. Louise Ellis, the islands’ deputy director of economic development, said the route was planned before the Sea Lion project and was unrelated to transporting cargo for it. The route, expected to open later in the year, would carry construction materials and fresh goods, including food and beverages. It had been discontinued in the 2000s after being considered unfeasible.
