This week the U.S. re-established diplomatic relations with Cuba. Among other things, this means that a U.S. embassy has been officially located in Havana. If you have questions about how U.S. relations with Cuba are progressing, the Embassy's site might be a good place to look for answers:
one fact sheet on the site makes clear that, "The embargo on Cuba is
still in place and legislative action is required to lift it." So, if
you were hoping that low-cost Cuban cigars would soon be flooding the
shelves of your local retailers, you may be out of luck for now.
