Rum distilleries and shopping malls are among the Cuban businesses newly banned by the US

Washington has just made it tougher for Americans to visit or do business in Cuba.

The US has rolled back on some of the historic normalization efforts put in place by former President Barack Obama towards Cuba by imposing new travel and business restrictions. Plans to implement new travel restraints were announced back in June and are went into effect Thursday.

Although Congress hasn't formally lifted the economic embargo imposed on Cuba since 1962, Obama's policies allowed for increased travel, trade, and communication between US citizens and Cuba. US citizens are still able to travel to Cuba, although tourist trips are heavily regulated by the Office of Foreign Assets Control (OFAC) and may require a license.

The State Department has published a comprehensive list of Cuban entities now banned from doing business with US citizens. From rum distilleries to shopping malls, here are some of the most interesting places listed.
