The UK Government has formally pledged its full support to businesses and individuals connected with the Falkland Islands after Argentina submitted legislation designed to strengthen sanctions over economic activity around the territory.
Overseas Territories Minister Uma Kumaran said the Government and Britain's diplomatic network stood fully behind companies and individuals supplying goods and services to the islands, including businesses operating in the hydrocarbons sector.
The statement was issued on 18 September, one day after President Javier Milei's government presented a bill intended to increase the penalties faced by companies and people participating in activities around the Falklands without Argentine authorisation.
UK promises businesses its full support
Kumaran said: “The UK Government and our diplomatic network stands fully behind those businesses and individuals. They have our full support.”
She described recent Argentine threats against businesses supplying the islands as unacceptable and said the charges being pursued against companies and individuals had no legal justification.
That is the UK Government's legal and diplomatic position. Argentina rejects it and claims sovereignty over the islands, which it calls the Malvinas, as well as jurisdiction over surrounding maritime areas and natural resources.
What would Argentina's bill do?
The legislation submitted by Argentina on 17 September would toughen the country's existing sanctions framework covering activities conducted around the Falklands and in maritime areas and continental shelf claimed by Buenos Aires.
According to the Argentine government, the measures would apply to unauthorised activity involving renewable or non-renewable natural resources. The proposed regime is aimed not only at operating companies but also at individuals, shareholders and suppliers connected with them.
The bill would revise legislation introduced in 2011 and create stronger penalties intended to deter companies from conducting business without approval from the Argentine authorities.
It has been submitted for consideration and is not yet law. Its eventual provisions remain subject to Argentina's legislative process.
National Security Council proposed
The bill also proposes the creation of a National Security Council led by Argentina's president.
The body would oversee national security policy and matters involving critical infrastructure and sovereignty. Its proposed membership includes Argentina's cabinet chief and its foreign, defence and economy ministers, alongside senior intelligence and legal officials.
President Milei's office said the legislation was intended to punish what Argentina considers the unlawful exploitation of its natural resources, encourage those involved to stop and provide the state with stronger tools against external threats.
Those descriptions reflect the Argentine government's position. The UK and Falkland Islands authorities do not recognise Argentina's claimed jurisdiction over licensed activity in and around the islands.
Sea Lion oil project at centre of dispute
The escalation follows Argentine action against companies and individuals linked to the Sea Lion offshore oil development north of the Falkland Islands.
The project is operated by Navitas Petroleum in partnership with the British company Rockhopper Exploration. The companies maintain that they hold valid licences issued by the Falkland Islands Government and have said they do not expect Argentina's measures to derail development.
Argentina said earlier in September that it had opened sanctions proceedings against at least 60 companies and individuals associated with offshore exploration around the islands.
Britain challenges Argentina's jurisdiction
The UK maintains that the Falkland Islands are British and that the islanders have the right to determine their own political future and develop their natural resources.
Kumaran described that control over natural-resource development as an integral part of the islanders' right to self-determination.
She also said attempts to use international mechanisms against people for doing business with the Falklands were illegitimate and promised that the UK would work with the Falkland Islands Government to protect the islanders' wishes.
Latest escalation in longstanding dispute
Argentina continues to claim sovereignty over the Falkland Islands despite the territory being administered by the United Kingdom. The two countries fought a 10-week war after Argentine forces invaded the islands in 1982.
The latest development goes beyond the earlier announcement that tougher sanctions were being prepared. Argentina has now submitted the legislation, while the UK has responded with a formal ministerial statement promising diplomatic and governmental backing for affected businesses.
That support does not prevent Argentina from pursuing measures through its domestic system, but it signals that London will contest attempts to impose Argentine jurisdiction upon companies operating under Falkland Islands licences.
