Argentina's foreign minister, Pablo Quirno, delivered the remarks at an event organised by the Argentine Council for International Relations in Buenos Aires. Among those in attendance was David Cairns, the UK's ambassador to Argentina, who was photographed listening to Quirno before leaving shortly after the minister returned to his seat.
Quirno said that President Javier Milei's government has a strategy for the "peaceful" assertion of Argentinian sovereignty over the Falkland Islands. He stated: "The British government not only refuses to enter into negotiations to resolve the sovereignty dispute, but is also taking unilateral measures regarding the exploitation of natural resources in the maritime areas that are part of the controversy."
He added: "Preventing the exploitation of our resources from consolidating the British occupation is part of a strategy to recover, through peaceful means, the full exercise of our sovereignty."
Last month, Milei told the UN general assembly that the international organisation had failed his country, condemning the Sea Lion oil project in the North Falkland Basin as an "unlawful act". Argentina has accused the UK of flouting a 1976 UN resolution ordering both parties to desist from unilateral action on the islands.
The Sea Lion project represents a significant offshore oil development in waters around the Falklands, which Argentina claims as part of its territory. The UK maintains that the Falkland Islanders have the right to self-determination and has not opened sovereignty negotiations.
