CARACAS, Venezuela — Venezuela’s government condemned U.S. sanctions on the country’s vice president, saying Tuesday that the Trump administration’s designation of Tareck El Aissami as a major drug trafficker represented an unprecedented and “highly dangerous” infringement on the South American nation’s sovereignty.

In a series of defiant messages posted on social media, El Aissami said the “miserable and defamatory aggression” only deepens his commitment to revolution started by the late Hugo Chavez and won’t distract him from his job of rescuing Venezuela’s crashing economy from what he called sabotage by its conservative opponents.

“They’ll never be able to defeat our unbreakable resolution to be free forever,”he said.
