LIMA, (Reuters) – The Organization of American  States called yesterday for Britain and Argentina to re-open  talks on the sovereignty of the disputed Falkland Islands,  where a British company has made a major oil find. Argentina, which has claimed the South Atlantic islands  since Britain established its rule in the 19th century, invaded  them in 1982, sparking a two-month war that ended with  Argentina’s defeat and withdrawal from the archipelago.

The OAS — a hemispheric forum that includes all nations in  the Americas except Cuba and Honduras — voted at a meeting in  Lima, Peru in favor of a resolution demanding the two nations  restart talks on the archipelago’s sovereignty.

Peru’s representative to the OAS announced that the vote  was unanimous.

Argentina objects to plans by British oil explorer  Rockhopper <RKH.L> to develop the Sea Lion well, the first oil  discovery in the islands.

“This illegal activity has many environmental risks for the  region, as we’re seeing now in the Gulf of Mexico,” Argentina’s  foreign minister, Jorge Taina, told the OAS general assembly in  Lima.

“In addition there is also the belligerent and aggressive  attitude the British government has, which is also a cause of  concern for the continent as a whole,” he said.

In addition, the OAS general also decided that it was no  yet the time to readmit Honduras, which was expelled from the  group following a coup last June.

Instead the OAS decided to send a mission to Honduras that  will assess the state of democracy in the Central American  country and produce a report that would be used to decide  whether to readmit Honduras at a future date.
