Argentine President Javier Milei has threatened to impose sanctions on companies involved in oil exploration activities near the Falkland Islands, known as Las Malvinas in Argentina, as Buenos Aires continues to assert its sovereignty claim over the disputed South Atlantic territory.
In a televised address on Thursday, Milei said his government would seek approval for urgent legislation aimed at increasing penalties against companies operating near the islands without authorisation from Argentina.
The proposed measures would target companies involved in the Sea Lion offshore oil project, a deep-water drilling venture located about 220 kilometres north of the Falkland Islands and being developed by UK-based Rockhopper Exploration and Israel’s Navitas Petroleum.
Milei said the sanctions could extend beyond the companies themselves to include suppliers, shareholders and directors involved in the project. He added that affected firms could face restrictions on future operations in Argentina.
The Argentine government argues that the drilling project violates a United Nations resolution calling on Argentina and the United Kingdom to avoid unilateral actions in the disputed territory.
The move comes as Milei seeks to strengthen support for his presidency, with the Falklands dispute remaining one of the few issues that has broad political significance across Argentina.
The United Kingdom rejected Milei’s position, with Defence Secretary Wes Streeting saying the comments reflected domestic political concerns rather than the status of the islands.
“The Falklands are British because Falkland Islanders choose to be British,” Streeting said, adding that Britain’s commitment to the territory remained unchanged.
The UK has repeatedly pointed to a 2013 referendum in which residents of the islands overwhelmingly voted to remain a British overseas territory.
Rockhopper Exploration said the latest development was not expected to have a significant impact on the Sea Lion project, which is scheduled to begin drilling operations this year, with production targeted for 2028.
The dispute over the Falkland Islands has remained a sensitive issue between Argentina and Britain since the 1982 war, which resulted in the deaths of more than 900 people on both sides.
Milei’s renewed focus on the issue has also drawn criticism from opposition lawmakers, who accused him of using the sovereignty dispute to divert attention from domestic challenges, including declining approval ratings linked to his economic reforms.
The Argentine president has also sought to highlight his relationship with United States President Donald Trump, after discussions over Washington’s position on the Falklands issue. The United States has historically maintained a neutral stance on the sovereignty dispute.
