Argentina’s Milei threatens sanctions as he refocuses on Falklands

Key points

• Britain's Defence Secretary, Wes Streeting, remarked on Friday that Milei's statement "tells us more about domestic politics in Argentina than it does about the Falkland Islands".
• London frequently refers to a 2013 referendum in which the roughly 4, 000 islanders voted overwhelmingly to remain British in response to questions over sovereignty.
• Britain and Argentina fought the 1982 war over the islands that killed more than 900 individuals from both sides.
• Argentine President Javier Milei has threatened sanctions against firms drilling for oil near the Falkland Islands.
• "The Falklands are British because Falkland Islanders choose to be British, " he continued.

In a televised address on Thursday, Milei remarked he would seek approval of urgent legislation to toughen penalties for businesses operating near the islands without approval from Buenos Aires. Argentina claims sovereignty over the South Atlantic archipelago. It it calls Las Malvinas.

Milei's hardened stance is viewed as a bid to revive backing for his libertarian presidency, with the Falklands problem one of the few that cuts throughout political lines.

For context, the sanctions would target the Sea Lion project, a deep-sea oil field regarding 140 miles (220 kilometres) north of the islands being developed by the UK's Rockhopper Exploration and Israel's Navitas Petroleum.

Milei remarked the sanctions would extend beyond the two firms to suppliers, shareholders and directors and that businesses involved could be barred from operating in Argentina altogether.

Argentine war veterans and environmental lawyers have already filed a lawsuit seeking to halt the project. It milei remarked violates a United Nations resolution urging Argentina and the UK to avoid unilateral action around the islands.

"The Falklands are British because Falkland Islanders choose to be British, " he continued. "Our commitment to the Falklands is absolute and unshakeable."

Rockhopper remarked in an official note that it does not expect the latest development to have a "material effect" on the Sea Lion project. The firm hopes to start drilling this year, with production by 2028.

Milei's revival of the dispute is seen as a bid to overturn domestic criticism of his relations with United States President Donald Trump. It some have called subservient.

Nevertheless, the Argentine president hopes to show that the relationship has the potential to reap rewards, with Trump having hinted that Washington could alter its neutral stance on the Falklands to turn it in Argentina's favour.

Trump lately declined to say whether the US would back the UK in a future Falklands conflict, criticising Britain instead for not doing more to backing the US-led bombing campaign against Iran.

Britain and Argentina fought the 1982 war over the islands that killed more than 900 individuals from both sides. The conflict still shapes Argentina's national identity and remains one of the few problems that unites its otherwise divided political class.

Milei has faced accusations from opposition MPs that he is exploiting the dispute for political gain as his approval ratings slump to 34 percent.

Al Jazeera's correspondent in Buenos Aires, Teresa Bo, remarked the timing owes as much to domestic politics as to Washington.

"Milei's approval ratings have been falling as Argentines feel the impact of his harsh austerity plan, " she remarked.

"And the Malvinas are one of the few issues capable of uniting Argentines across the political spectrum."

For now, argentina's Milei threatens sanctions as he refocuses on Falklands remains the part of the story worth watching, and further updates are likely as more details are confirmed.
