A development zone created by the Cuban government at the Port of Mariel is offering tax incentives that some say may give manufacturers there an edge in exports to Latin America.

But for U.S. companies looking to manufacture in the Caribbean for export to Latin America, Cuba isn’t the only country that offers incentives to investors. While Mariel may be a gateway to the Cuban market, experts say even if the U.S.-Cuba trade embargo is lifted, reasons remain to be wary of large foreign direct investment in Cuba.
