Argentine President Javier Milei said in a televised national address on 2026-06-25 that the prospect of two oil firms carrying out exploration in the Falkland Islands, which Argentina calls Las Malvinas, was an urgent threat to Argentine interests, and that he would send Congress a bill to strengthen Argentina's response to sovereignty violations. ^[1] Argentine President Javier Milei stated that his government will issue a decree to toughen sanctions on foreign companies operating in the Malvinas Islands and surrounding areas. ^[2] Argentine President Javier Milei said that 'winds of change' favorable to Argentina's claim to the Falklands were 'blowing around the world' and that Argentina needed to take the islands back. ^[3] UK Foreign Secretary Ed Miliband said on X that the UK's position on the Falkland Islands is unwavering, that the islands are British and will remain so because that is the overwhelming position of the Islanders, and that their right of self-determination is paramount and grounded in international law. ^[4] In a primetime address on 2026-09-03, Argentine President Javier Milei resurrected Argentina's claim to the Falkland Islands (called the Malvinas by Argentina), saying the islands are 'our future' and that Argentina must 'recover' them as a matter of national importance. ^[5] Argentina's President Javier Milei announced on Thursday that his government would deploy economic and diplomatic tools to sanction companies involved in offshore oil exploration near the Falkland Islands. ^[6] Argentine President Javier Milei, in a primetime speech in 2026, revived Argentina's claim to the Falkland Islands (which Argentina calls the Malvinas) and said he would sign decrees imposing sanctions on companies working on oil production around the islands. ^[7] British Defence Minister Wes Streeting said on 2026-06-26 that Milei's statement 'tells us more about domestic politics in Argentina than it does about the Falkland Islands,' and that Britain's commitment to the Falklands is 'absolute and unshakeable.' ^[8] Rockhopper Exploration's stock was down 8% on Friday morning, the day after Milei's address. ^[9] The Sea Lion oil field project, located about 140 miles north of the Falkland Islands, is operated by Tel Aviv-listed Navitas Petroleum and has London-listed Rockhopper Exploration as a shareholder with a 35% interest; development work could begin in the coming months. ^[10] President Javier Milei announced that a bill will be sent to Congress to create a national security council intended to defend sovereignty and regain the Malvinas Islands. ^[11] President Javier Milei stated that any additional advancement in the Malvinas Islands will be considered a violation of national security. ^[12]
