Trip to serve as a powerful symbol of relationship Havana, Washington are now working to establish

Eyeing a new future with the United States, Cubans are preparing their famed capital for a long-awaited visit by US President Barack Obama, who will make history when Air Force One touches down in Havana.

Obama's visit to the island nation will serve as a powerful symbol of the relationship that the US and Cuba are now forging. For Obama, the trip offers one of the last, best chances to advance the diplomatic opening with President Raul Castro before Obama leaves office next year.
