The Organization of American States cleared the way for Cuba's possible return to the group by lifting a 47-year ban on the communist-run country, a move backed by Washington despite initial objections.

The vote by acclamation Wednesday to revoke a 1962 measure suspending the island from the body not only toppled a Cold War landmark but was the latest sign of the end of Cuba's isolation in a region increasingly governed by leftist leaders.

Even traditional U.S. ally El Salvador this week restored ties with Cuba, meaning that every country in the hemisphere except for the United States has re-established relations. The U.S. embargo of Cuba also remains deeply unpopular in much of Latin America.
