Milei to Take Falklands Oil Spat to UN as Britain Pushes Back

Argentina's President Javier Milei will address the United Nations General Assembly on Wednesday, with tensions mounting between Buenos Aires and London over oil exploration around the Falkland Islands, a largely self-governing British overseas territory whose sovereignty Argentina has long contested.

Earlier this month, Argentina launched sanctions proceedings against more than 60 companies and individuals tied to an offshore drilling project. British officials responded sharply. Uma Kumaran, the British Parliamentary Under-Secretary of State for Overseas Territories, described the move as "unacceptable" in a statement on Friday, adding that "the Falkland Islands are British and they have the right to develop their natural resources as they see fit."

Analysts and political commentators expect Milei to reaffirm Argentina's position during his UN speech. On Thursday, he is scheduled to meet Israeli Prime Minister Benjamin Netanyahu, a close ally. The Falklands drilling project has strong Israeli connections.

Argentina's claim to the South Atlantic islands it calls the Malvinas remains central to its national identity. The country invaded the archipelago in 1982, fighting a 10-week war that ended in surrender to Britain and is still marked in Buenos Aires by street murals honouring fallen soldiers.

In a televised address this month, Milei said the drilling project violates a 1976 UN General Assembly resolution that urged both countries to resolve the sovereignty dispute through dialogue and avoid unilateral decisions. His speech came days after US President Donald Trump, a Milei ally, suggested Washington could reconsider its traditionally neutral stance on the dispute.

Milei's firmer posture marks a notable shift for a president previously criticised by opponents for showing little interest in the sovereignty issue while pursuing closer ties with the US and Europe. Argentina's opposition now accuses Milei, who is expected to seek reelection in 2027, of using the dispute to shore up domestic support.

"It's simply something to look good in the eyes of society or to try to shift the agenda," said Guillermo Michel, a Peronist opposition congressman in the chamber of deputies.

A study by the Buenos Aires-based consultancy Inteligencia Analitica found that Milei's televised address produced only a modest improvement in his public image. "The Malvinas issue in Argentina transcends the president's speech," said Marcelo Escolar, the firm's director.

Last week, Milei presented a bill aimed at toughening sanctions on those deemed to unlawfully participate in activities utilising natural resources in Argentina's maritime spaces and continental shelf. The bill will first be referred to committee as the government weighs its legislative priorities.

Milei lacks a majority in Congress but has managed to pass significant economic reforms. Marcelo Seghini, a defence adviser in the lower house, said that while some parts of the sovereignty bill may have bipartisan support, other provisions unrelated to the Falklands dispute may spur opposition.

Owners of the Sea Lion offshore project, Navitas Petroleum and Rockhopper Exploration, have indicated they do not expect Milei's actions to derail development.
