American and Cuban diplomats will meet early next week for a third round of historic talks on restoring diplomatic ties and reopening their embassies, US officials said Friday. Top US diplomat for Latin America, Roberta Jacobson, will travel back to Havana on Sunday for the talks between the two old Cold War foes expected to open on Monday and last until mid-week. Both sides said progress had been made in their last negotiations in Washington on February 27 aimed at restoring diplomatic ties severed for more than half a century, but cautioned that differences remained. Jacobson will again meet with Cuba’s chief negotiator Josefina Vidal in a bid to hammer out remaining issues as both sides eye an upcoming Summit of the Americas in Panama on April 10-11.
