Argentina threatened sanctions against oil companies in the disputed Falkland Islands

Argentine President Javier Milei has intensified claims over the British-controlled territory, announcing that he will impose sanctions on companies extracting oil in the Falkland Islands. He spoke about this in an address on national television on September 3.

The statement came days after US President Donald Trump said he was reconsidering America's neutral stance on the islands. Milei said that exploration by oil companies in these islands, which Argentina calls Las Malvinas, poses a serious threat to the country's interests. He expressed this view 44 years after Argentina was defeated by Britain in the war.

Milei, an ally of Trump, referred to potential changes in the US position, saying the "winds of change" were blowing in Argentina's favor. He also announced that he is sending a bill to Congress that would strengthen measures against violations of the country's sovereignty.

Britain, which has controlled the territory since 1833, announced on September 4 that its position remains unchanged.

"The islands are British and will remain so because the overwhelming majority of the islanders support this," UK Foreign Secretary Ed Miliband wrote on the X network.

He added that the right to self-determination based on international law is paramount and Britain will firmly defend it. British Defence Secretary Wes Streeting, meanwhile, noted that Milei's words reflect Argentine domestic politics.

Previously, Milei preferred to resolve the Falklands claims through diplomacy. However, in recent months, following increased oil production and Trump's frequent statements about the islands, he has taken a firmer stance.

In an interview with GB News on September 3, Trump said he was not sure Britain was ready to fight for the islands again.

"I don't know if you have the capability to do it. The Falklands issue is very interesting because your country is not the country it was 20-25 years ago," Trump said, referring to Britain.

A change in the US position on the Falklands was among the options considered by the Pentagon in early 2026 to pressure NATO allies who did not support US military operations in a war with Iran.

Following the Argentine invasion in 1982, then-British Prime Minister Margaret Thatcher sent naval forces to the South Atlantic. After 74 days of fighting, Britain regained control of the islands, and more than 900 people died in the clashes.

Milei called Thatcher a great leader in 2023. However, in his September 3 address, he described Britain as a country now in decline.

Saying that the islands are Argentina's future, Milei announced that he would send an urgent bill "On the Protection of National Sovereignty" to Congress. The document provides for strengthening penalties for unauthorized operations around the islands, applying sanctions to suppliers as well, and extending the legislation to other activities affecting natural resources.

The "Sea Lion" oil field, located approximately 140 miles north of the Falkland Islands, is operated by Navitas Petroleum, a company listed on the Tel Aviv Stock Exchange. London-listed Rockhopper Exploration is also among its shareholders.

When the field was first drilled in 2010, Argentina deemed it illegal. The field is estimated to hold approximately 1.7 billion barrels of oil reserves, making it a major world-class discovery.
