Argentine President Javier Milei has vowed to sanction oil companies drilling in the Falkland Islands, a British overseas territory claimed by Argentina, saying "Argentina will not stand idly by" if the project moves forward. The Sea Lion oil project, planned by Rockhopper Exploration and Navitas Petroleum, is set to begin drilling next year and pumping oil in 2028, despite Argentine claims that it is an illegal exploitation of resources. Milei also announced new funding for a naval base near the islands, citing concerns over national security. It comes amid escalating tensions between Argentina and Britain, with US President Donald Trump reviewing his country's neutral stance on the dispute.

Story summary
Argentina's President Javier Milei has announced that his country will sanction oil companies drilling in the Falkland Islands, a British overseas territory claimed by Argentina. The decision comes as tensions escalate between the two countries over sovereignty of the islands, which have been at the center of a long-standing dispute since Argentina invaded them in 1982.
Milei cited comments from US President Donald Trump, who recently suggested that the US may reconsider its neutrality on the issue, as evidence that "winds of change" are favoring Argentina's claim. However, the UK has rejected Milei's claims, with Foreign Secretary Ed Miliband saying that the islands will remain British because they are the "overwhelming position of the Islanders" and their right to self-determination is paramount.
The dispute has been further complicated by Trump's history of seeking revenge on countries that he perceives as having wronged him, which some believe may be influencing Milei's actions. The situation remains highly sensitive, with both sides dug in on their positions.
In the past few days, several UK ministers have issued statements reaffirming the country's commitment to the Falklands, including Defence Secretary Wes Streeting and Education Secretary Lucy Powell. Meanwhile, Trump has been accused of using his vendetta against countries that did not support him in the Iran war as leverage to favor Milei's claims.
The dispute over the Falkland Islands is a long-standing one, with Argentina claiming sovereignty over them since 1820 and the UK maintaining control after a brief but bloody conflict in 1982. The islands have been a British overseas territory ever since.
