Milei to address UN as Argentina-Britain tensions rise over Falklands oil project

Washington, United States. Argentina’s President Javier Milei is due to address the United Nations General Assembly on Wednesday as tensions with Britain escalate over offshore oil exploration around the Falkland Islands, whose sovereignty Argentina disputes.

Argentina has begun sanctions proceedings against more than 60 companies and individuals linked to an offshore drilling project near the islands, which Argentina calls the Malvinas.

British response

Britain’s Parliamentary Under-Secretary of State for Overseas Territories, Uma Kumaran, described Argentina’s actions as “unacceptable” in a statement on Friday.

“The Falkland Islands are British and they have the right to develop their natural resources as they see fit,” Kumaran said.

Analysts and political commentators said Milei is likely to reaffirm Argentina’s position in his UN speech.

UN resolution and sovereignty dispute

In a televised address this month, Milei said the drilling project violates a 1976 UN General Assembly resolution urging Argentina and Britain to resolve the sovereignty dispute through dialogue and avoid unilateral decisions.

Argentina’s claim to the South Atlantic islands remains central to its national identity. Argentina invaded the archipelago in 1982, triggering a 10-week war that ended with its surrender to Britain. The conflict is still commemorated in Buenos Aires through street murals honouring fallen soldiers.

Political context

Milei is due to meet Israeli Prime Minister and close ally Benjamin Netanyahu on Thursday. The Falklands oil drilling project has strong Israeli ties.

His statement on the dispute came days after US President Donald Trump, a Milei ally, suggested that Washington could reconsider its traditionally neutral position on the Falklands dispute.

Milei’s tougher position represents a shift for a president criticised by opponents for showing little interest in the sovereignty issue while pursuing closer relations with the United States and Europe. Argentina’s opposition has accused Milei, who is expected to seek re-election in 2027, of using the dispute to strengthen 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 Buenos Aires-based consultancy Inteligencia Analitica found that Milei’s televised address resulted in 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.
