The announcement is expected to come from their respective capitals, following Friday's anticipated announcement of Cuba's removal from the list of state sponsors of terrorism.

Cuba will be formally removed from the list 45 days after President Barack Obama announced his intention to remove the Caribbean state, which came in mid-April.

Last week, Cuban diplomats met in Washington with U.S. diplomats in the latest round of talks since the two countries began negotiating the re-establishment of diplomatic ties in December.

Both sides expressed optimism and called the talks "very productive," foreseeing an agreement soon, but several points remain, particularly regarding the conduct of U.S. diplomats in Cuba, which Havana insists must abide by the Vienna Convention.
