Milei Says Falklands are Argentine as He Moves to Sanction Oil Projects

Argentine President Javier Milei declared Friday that the Falkland Islands are Argentine “by history and by right” as he moved to intensify economic pressure on companies involved in oil development around the disputed archipelago.

Milei said Argentina would prohibit businesses directly or indirectly participating in Falklands projects from operating in Argentine territory without Buenos Aires ’ authorization.

“The Malvinas (Falkland Islands) are Argentine by history and by right. There is no discussion about it,” Milei said.

Oil Companies Face a Choice

The proposed restrictions put offshore energy development at the center of Argentina’s renewed sovereignty campaign.

Milei said companies involved in projects around the islands would have to decide whether to maintain those operations or retain access to Argentina.

“Those operating on our islands behind the Argentine government’s back will have to choose between an illegal venture in disputed territory and a profitable and secure operation in a sovereign country with clear rules and predictability. You cannot do both.”

Argentina is expected to accelerate enforcement procedures against companies participating in oil extraction in waters it considers Argentine.

Milei said Buenos Aires would use both economic and diplomatic measures against state and private actors involved in such activity.

Sea Lion in Focus

The Sea Lion oil project has emerged as the immediate target of the tougher policy.

The field, located north of the Falklands, is estimated to hold about 1.7 billion barrels of oil and is being developed by Britain’s Rockhopper Exploration and Israel’s Navitas Petroleum.

Rockhopper holds 35% of the project, with Navitas controlling the remainder.

Drilling is planned to begin within months, with oil potentially flowing from early 2028. The field is expected to remain productive for more than 30 years.

Milei argued that building production infrastructure would materially strengthen the developers’ ability to extract resources from waters claimed by Argentina.

“If we do not act swiftly, they will have the material capacity to access the oil that lies underneath our sea,” he said.

Argentina has already characterized Rockhopper and Navitas as operating without lawful Argentine authorization.

Milei Rejects Islander Self-Determination

Milei also adopted an uncompromising position on the political status of the islands.

He said Britain’s occupation of the territory in 1833 had created what Argentina regards as a continuing colonial situation and argued that the current population could not legitimately determine the islands’ sovereignty.

That position directly rejects the relevance of the March 2013 referendum, in which 99.8% of participating islanders voted to remain a U.K. Overseas Territory.

The U.K. position, as cited following Milei’s speech, remains that the islanders have the right to determine their political future and that British support for that principle is unchanged.

Trump Remarks Bolster Buenos Aires

Milei linked the harder Argentine stance to recent comments by U.S. President Donald Trump, saying Washington was reassessing its historical position on the dispute.

He portrayed Argentina’s relationship with the U.S. as increasingly important to the Falklands claim, pointing to what he described as shared Western interests and Argentina’s strategic position.

Milei said the international environment was becoming more favorable to Buenos Aires.

“Winds of change favorable to our claim are blowing around the world,” he said.

Trump had also questioned whether the U.S. would assist Britain in another conflict over the islands and raised doubts about Britain’s ability to defend the territory because of its distance from the U.K.

Milei described the U.S. president’s remarks as significant for Argentina’s sovereignty campaign.

Britain Cast as Declining Power

The Argentine president coupled the sanctions announcement with an attack on Britain’s long-term position.

He argued that the U.K. faced economic, demographic and migration pressures while Argentina’s strategic prospects were improving.

“It is clear that Britain is traveling down a path of decline. Meanwhile, Argentina’s future is flourishing and will prevail,” Milei said.

The rhetoric marks a sharper approach from a president who had previously emphasized diplomacy and engagement with the islanders while maintaining Argentina’s sovereignty claim.

His latest position places commercial pressure, particularly over offshore energy, alongside diplomatic efforts as a principal instrument of Argentina’s Falklands strategy.
