Milei gave the United Kingdom a two-week ultimatum on Monday evening, saying it must halt all work on the Sea Lion oil project or Argentina will ask the International Tribunal for the Law of the Sea, a maritime court in Hamburg, Germany, to order a stop to the project.
He called the operations “the illegal plundering of our resources” and declared “Argentina will not stand idly by” as the UK causes “irreversible and irreparable” damage.
The companies developing the project, Israel’s Navitas and Britain’s Rockhopper, have shrugged off Argentina’s threats, insisting they have valid exploration licences issued by the UK.
The tribunal, an independent court established under the 1982 UN Convention on the Law of the Sea, can issue legally binding emergency orders. But even if it ordered the UK to halt the project, it has no means of forcing the government to comply.
The UK rejects Argentina’s sovereignty claim, arguing that the islanders have the right to determine their own future and develop their natural resources. In a referendum in 2013, residents of the Falklands voted overwhelmingly to remain a British overseas territory. Argentina says the islands were populated illegally.
Milei’s administration has already taken legal action against the project authorised by Britain, arguing it violates a United Nations resolution calling for both sides to desist from unilateral actions in the islands until their dispute is resolved.
Buenos Aires has doubled down on its claim over the Falklands since United States President Donald Trump said Washington was open to reviewing its historically neutral stance on the territory.
The British government for its part has said it stands behind the businesses operating near the Falklands.
The dispute over the Falkland Islands led to a war between Britain and Argentina in 1982. It killed 649 Argentinian soldiers, 255 British soldiers and three islanders after Argentina invaded the archipelago that year.
