Argentina's president called Britain a "crude colonial power" on Thursday after Prime Minister David Cameron said the Falkland Islands should remain British territory.
Argentine President Cristina Fernandez took issue with remarks a day earlier by Cameron, who praised the British troops who retook the Falklands from the Argentines during the 1982 war over the islands.
"As long as the Falkland Islands want to be sovereign British territory, they should remain sovereign British territory _ full stop, end of story," Cameron said in the House of Commons.
The South Atlantic islands are claimed by Argentina, which refers to them as Las Malvinas. Fernandez has insisted Argentina and Britain should negotiate over the islands, as the U.N. General Assembly has urged.
She said Argentina intends to keep raising its demands in international forums for negotiations with the British.
"We're going to say that in the 21st century they continue to be a crude colonial power in decline," Fernandez said during a televised ceremony in the northeastern province of Misiones.
Referring to Cameron's statements, Fernandez said that Argentina's foreign minister considered it an "expression of arrogance."
Fernandez on Monday had called for dialogue with London on the issue during a visit to Buenos Aires by U.N. Secretary-General Ban Ki-moon.
