Cuba has rejected a proposal by two U.S. businessmen who are seeking to start the first American manufacturing plant in Cuba in more than 50 years. Cuba rejected the proposal by Cleber, LLC, a manufacturer based in Paint Rock, Alabama. The company was planning to build a $5 million facility in a Special Economic Zone west of Havana that Cuba has designated to attract foreign investment. But, after a year of negotiations, Politico reports officials in Cuba determined the plan was not “high-tech enough.” One of the businessmen involved in the projected added “underlying everything is the embargo,” suggesting that greater trade-related tensions influenced the rejection.
