An academic has written that the Revolutionary Armed Forces of the Republic of Cuba (FAR) does not control 60% of the economy within the Republic of Cuba.

The percentage of control is not as important as what entities are controlled- specifically the location of those entities:

Hotels, restaurants, retail stores, ground transportation in Old Havana… where almost all individuals subject to United States jurisdiction who visit the Republic of Cuba under the educational (which includes “people-to-people”) category want to visit or need to visit to be in compliance with regulations administered by the Office of Foreign Assets Control (OFAC) of the United States Department of the Treasury and soon-to-be published (by 16 September 2017) list of restricted/prohibited entities by the United States Department of State.

Important to remain focused on the impact rather than upon the percentage.
