The US has imposed sanctions on Venezuela’s state-owned oil firm PDVSA and urged the country’s military to accept a peaceful transfer of power.
National Security Adviser John Bolton said President Nicolás Maduro and his allies could “no longer loot the assets of the Venezuelan people”.
Efforts by the opposition to unseat Mr Maduro have increased in recent days.
The US and more than 20 countries have recognised opposition leader Juan Guaidó as interim president.
