Argentine President Javier Milei has intensified Argentina’s sovereignty campaign over the British-controlled Falkland Islands, announcing sanctions tied to offshore oil development and pledging diplomatic, economic and legal action while planning a new military base in Tierra del Fuego.

Argentine President Javier Milei sharply escalated his government’s campaign to reclaim sovereignty over the British-controlled Falkland Islands on Thursday, announcing sanctions against companies involved in offshore oil projects and pledging to pursue Argentina’s territorial claim through diplomatic, economic and legal means.

“The islands are ours, they were taken from us, and they are indispensable for Argentina in the coming decades,” Milei said during a national address, according to The Wall Street Journal. “Argentina won’t stand by with its arms crossed.”

Milei, who calls the South Atlantic archipelago by its Argentine name, the Malvinas, said his administration intends to employ all “diplomatic, economic, judicial and legal tools” available to advance Argentina’s longstanding sovereignty claim.

The president also announced plans for a military base in Tierra del Fuego, Argentina’s southernmost province, as part of a broader effort to reinforce the country’s strategic position in the South Atlantic.

“Securing our preeminence in this territory is not a political whim, it is a matter of survival,” Milei said. “The Malvinas are the future, not just a question of our past.”

The tougher position includes economic measures directed at companies participating in offshore oil development around the islands. Argentina disputes Britain’s authority over the territory and considers exploitation of surrounding natural resources part of that sovereignty dispute. Reuters separately confirmed Friday that Milei’s government was moving to sanction companies connected to Falklands oil development.

Britain responded by reaffirming that its position on the islands has not changed.

A spokesman for British Prime Minister Andy Burnham said the United Kingdom’s commitment to the Falklands remains “unwavering.”

“The Falkland islanders are British, with the right to determine their own future,” the spokesman said.

The British government continues to administer the Falklands as a British Overseas Territory, a status reflected in current U.K. government information.

Milei directly rejected Britain’s self-determination argument Thursday, saying the people living on the islands constitute a “population implanted in a usurped territory.” He also rejected the validity of referendums conducted among Falkland residents concerning their political status.

The confrontation intensified days after President Donald Trump drew new attention to the decades-old dispute by suggesting Monday that Washington could reconsider its position.

The United States has recognized British administration of the islands while remaining neutral on the competing sovereignty claims.

“I always review every position; that’s just one of many,” Trump said when asked about the dispute.

Milei subsequently suggested Argentina’s close relationship with the United States could strengthen Buenos Aires’ diplomatic effort to regain control of the islands. The Wall Street Journal reported that Trump’s remarks brought renewed international attention to Milei’s push.

Milei’s more assertive Falklands strategy also comes as he confronts declining public approval and economic concerns at home ahead of Argentina’s next presidential election.

His government has balanced the federal budget and brought inflation sharply lower from levels exceeding 200% when he assumed office in December 2023. At the same time, the broader economic recovery has remained difficult for many Argentines, with job losses and rising household debt placing additional pressure on families.

An AtlasIntel survey conducted for Bloomberg put Milei’s approval rating at 37% in July, among the lowest readings of his presidency.

Speaking at a conference Wednesday, Milei framed next year’s election in stark terms.

“If we don’t win in next year’s elections, it’s because society wants to commit suicide,” Milei said.

Michael Shifter, a Latin America scholar at the Inter-American Dialogue in Washington, said the Falklands have repeatedly served as a potent political issue for Argentine leaders during periods of domestic pressure.

“When you have political troubles, this is a tried and true way to try to get out of them and boost support,” Shifter said.

Milei had already begun speaking more frequently about Argentina’s sovereignty claim during 2026, but Thursday’s national address represented a substantially more forceful approach.

It was also a departure in tone from Milei’s earlier handling of relations with Britain.

After taking office, Milei — who has publicly expressed admiration for former British Prime Minister Margaret Thatcher — argued that the unresolved Falklands dispute should not prevent Argentina and Britain from developing productive commercial ties.

“We’ve decided to have an adult relationship,” Milei said at the time.

His latest address instead emphasized pressure on Britain and companies doing business around the islands.

“We will continue defending the interests of the Argentine nation tooth and nail,” Milei said. “No matter who it bothers.”

The sovereignty dispute stretches back nearly two centuries and remains one of the most emotionally charged foreign-policy issues in Argentina.

Britain has controlled the Falkland Islands since 1833, with the exception of the brief Argentine occupation that triggered the 1982 Falklands War.

Argentina’s military dictatorship invaded the islands in April 1982 and overwhelmed the small British force stationed there. Thatcher’s government responded by dispatching a naval task force thousands of miles into the South Atlantic to recapture the territory.

The conflict lasted 74 days.

British forces ultimately regained control of the islands after fighting that killed 649 Argentine and 255 British military personnel.

Argentina’s defeat had major domestic consequences. The military government that ordered the invasion lost further legitimacy following the war, and democratic government was restored in Argentina in 1983.

Neither the war nor Argentina’s return to democracy resolved the underlying sovereignty dispute.

Argentina has continued to claim the islands, while Britain maintains that their political future should be determined by the islanders themselves.

The approximately 3,200 residents of the Falklands have overwhelmingly supported maintaining their relationship with Britain.

In a 2013 referendum, 99.8% of participating voters chose to retain the islands’ status as a British Overseas Territory, a result Britain cites as evidence of the islanders’ preference for continued British sovereignty. Milei’s government rejects the referendum as a legitimate basis for resolving the territorial dispute.

The disagreement is now increasingly intertwined with the economic value and strategic importance of the surrounding South Atlantic.

Milei’s sanctions announcement brings offshore energy development directly into Argentina’s renewed sovereignty campaign, while his proposed Tierra del Fuego military base would strengthen Argentina’s physical presence in the region.

Together with his commitment to pursue diplomatic, judicial and economic pressure, the moves mark a significant change from the more restrained approach Milei articulated early in his presidency and place the Falklands dispute prominently back on the agenda between Buenos Aires and London.
