HAVANA (AP) — The United States and Cuba have agreed to resume bilateral talks on migration issues next month, a State Department official said Wednesday, the latest evidence of a thaw in chilly relations between the Cold War enemies.

Havana and Washington just wrapped up a round of separate negotiations aimed at restarting direct mail service, which has been suspended since 1963. Both sets of talks have been on hold in recent years in a dispute over the fate of U.S. government subcontractor Alan Gross, who is serving a 15-year jail sentence in Havana after he was caught bringing communications equipment onto the island illegally.
