Argentine President Javier Milei is preparing legislation to strengthen sanctions against companies operating in the Falkland Islands, which Argentina calls the Malvinas and claims despite Britain’s control. Argentina invaded the islands in 1982 and fought a 10-week war with Britain before surrendering. The government says it has begun sanctions proceedings against at least 60 companies and individuals linked to offshore oil exploration around the islands. The bill would impose tougher penalties for unauthorized operations, extend liability to affiliates and potentially cover activities affecting Argentina’s natural resources, including fishing. It follows a criminal complaint against companies connected to the Sea Lion offshore project. Analysts say the measures could create commercial uncertainty, complicate the project’s development and pressure Milei to escalate the dispute with Britain, while his libertarian coalition lacks a congressional majority. The legislation is also emerging after U.S. President Donald Trump suggested Washington could reconsider its traditionally neutral position on the Falklands dispute.
