The U.S. Treasury Department said on Wednesday it would authorize companies seeking licenses to resell Venezuelan oil to Cuba, according to guidance posted on the department's website, a move that could help ease the island's acute fuel scarcity. Since Washington took control of Venezuela's oil exports in early January in the aftermath of the capture of Venezuelan leader Nicolas Maduro, the South American country's supply to Cuba has ceased, worsening an energy crisis in the communist-run country that is hitting power generation and fuel for vehicles, houses and aviation.
