The Biden administration has reimposed crushing oil sanctions on Venezuela, admonishing President Nicolás Maduro's attempts to consolidate his rule just six months after the U.S. eased restrictions in a bid to support now fading hopes for a democratic opening in the OPEC nation.

A senior U.S. official, discussing the decision with reporters, said any U.S. company investing in Venezuela would have 45 days to wind down operations to avoid adding uncertainty to global energy markets. The official spoke on the condition of anonymity to discuss U.S. policy deliberations.
