Argentina has pledged to pursue 'full sovereignty' over the Falkland Islands following the UK's recent decision to return the Chagos Islands to Mauritius. Foreign Minister Diana Mondino welcomed this change, which she sees as a step away from 'outdated practices', and vowed to take 'concrete action' to reclaim the Falklands, referred to as Malvinas by Argentina. The move has sparked criticism from British politicians, including former Prime Minister Boris Johnson, who expressed concern over the implications for other British territories. While the UK has assured that its commitment to the Falklands remains 'unwavering', the historical context remains fraught due to the 1982 conflict over the islands. The agreement with Mauritius, which allows for continued military presence on Diego Garcia, has been described as a 'historic' decision by US President Biden. This development may intensify existing tensions between the UK and Argentina regarding territorial claims.
