President Barack Obama’s historic trip to Cuba this week has been accompanied by a series of announcements from U.S. businesses that they plan to do work in the Communist country.

On Friday, Starwood Hotels & Resorts Worldwide Inc., the hospitality giant mulling a Chinese takeover bid and operator of chains such as the Sheraton, St. Regis and Westin, announced that it had signed three hotel deals in Cuba. Marriott International Inc., meanwhile, said Sunday that it received approval from the U.S. Department of the Treasury’s Office of Foreign Assets Control to pursue business in Cuba.
