Argentine President Javier Milei escalated his country’s decades-old dispute with Britain over the Falkland Islands on Thursday, September 3, vowing new sanctions against oil companies operating near the British-controlled archipelago, days after President Trump suggested Washington’s long-standing neutral stance on the islands’ sovereignty was “under review.”
“The Falkland Islands are Argentinian, historically and legally. There is no debate,” Milei said in a televised address, warning that the Sea Lion offshore oil project could “create an incentive for the UK to deepen its occupation” and “continue exploiting our resources.” He said he would fast-track legislation enabling sanctions against companies involved in oil production near the islands, extending penalties to suppliers, shareholders and directors, and potentially barring such firms from operating or signing contracts in Argentina altogether. Milei credited Trump’s comments with creating “winds of change” more favourable to Argentina’s claim, framing the US as “a reliable partner” aligned with Western values.
Britain responded firmly. Foreign Secretary Ed Miliband said on X that “the UK’s position on the Falkland Islands is unwavering,” adding: “The Islands are British and will remain so because that is the overwhelming position of the Islanders. Their right of self-determination is paramount, grounded in international law.” The 1982 Falklands War killed 649 Argentine troops, 255 British service members and three islanders, and remains a deeply sensitive point in Argentina more than four decades later. Notably, Milei’s own approval rating has fallen to near the lowest of his presidency, and analysts note that reviving the nationalist Falklands cause, known in Argentina as Las Malvinas, could help rally domestic political support regardless of the dispute’s practical prospects. In a separate interview with The Economist, Milei struck a more conciliatory note, expressing a desire for a “consensus solution” with Britain and referencing the framework under which Britain returned Hong Kong to China as a possible model.
