Miami-Dade County has revoked the business license of Vanguard Energy, a company accused of facilitating fuel shipments to Cuba. County officials state the action aims to prevent the use of Miami-Dade as a hub for activities that violate U.S. federal law, specifically regarding trade with the island nation. The decision follows concerns that Vanguard Energy was involved in transactions undermining the U.S. embargo against Cuba. Details regarding the specific nature of the shipments and the extent of the alleged violations have not been fully disclosed. Vanguard Energy has not yet publicly commented on the license revocation. This move signals a stricter stance by Miami-Dade County on enforcing U.S. policy concerning Cuba. The revocation effectively prohibits the company from operating within the county.
