Argentina has condemned as an act of provocation Britain's decision to send Duke of Cambridge to the Falkland Islands next year for further training as a helicopter pilot.
Britain says Prince William's deployment there in the South Atlantic is routine. The Royal Air Force says he will not perform any ceremonial duties there.
However, Sebastian Brugo Marco, an official with responsibility for the South Atlantic territory, says Argentina cannot ignore the political content of the mission.
The BBC reports Prince William's deployment will be shortly before the 30th anniversary of the start of the Falklands War.
Britain has ruled the Falklands for more than 180 years, but Argentina insists it has a prior claim over the islands, which it calls Las Malvinas.
British Prime Minister David Cameron has said there can be no negotiations on the status of the islands unless the people of the Falklands want them.
