“We are preparing another package of sanctions to apply in this case,” Sullivan told CNN’s Dana Bash on “State of the Union.” “We’ve shown all along the way that we are not going to pull our punches, whether it’s on solar winds, or election interference, or Navalny when it comes to responding to Russia’s harmful activities.”
Sullivan said the sanctions will come once the US can “ensure that we are getting the right targets,” adding, “When we do that, we will impose further sanctions with respect to chemical weapons.”
“What we’re going to do is continue to rally support in the international community,” Sullivan said. “And if it turns out that China refuses to live up to its international obligations, we will have to consider our responses at that point, and we will do so in concert with allies and partners.”
The US, Sullivan said, is “showing Iran that if they choose not to negotiate in good faith and reassume their nuclear obligations, that it won’t just be the US — it’ll be the international community — that isolates them.”
He added: “America’s national security interests do not change. Our national security interest is to prevent Iran from ever acquiring a nuclear weapon. We believe diplomacy, and not military action, is the best way to do that.”
