"The United States is putting foreign financial institutions on notice that they will face sanctions for being involved in facilitating illegitimate transactions that benefit Nicolas Maduro and his corrupt network. We will not allow Maduro to steal the wealth of the Venezuelan people," Bolton said.
US Special Representative for Venezuela Elliott Abrams said on Tuesday that Washington is considering imposing sanctions on third-country actors in response to the Venezuelan crisis.
Later in the day, US Vice-President Mike Pence, speaking at the Latino Coalition Legislative Summit, announced that Washington would strip some 77 Venezuelans of visas, including a lot of country's officials and the members of their families.
Incumbent President Nicolas Maduro has called Guaido a puppet of the United States and called his move an attempt to stage a coup orchestrated by Washington.
Russia, China, Cuba, Mexico, Turkey and a number of other states have voiced support for the Maduro government.
