Vice President JD Vance, after returning from unsuccessful negotiations with Iran over the weekend, said Monday that it is up to the Islamic Republic to make the next move on peace talks with the U.S.

“Whether we have further conversations, whether we ultimately get to a deal, I really think the ball is in the Iranian court, because we put a lot on the table,” Vance said in a Fox News interview.

He stressed that if America’s “red lines” on Iran’s nuclear ambitions are met, “then this can be a very, very good deal for both countries.”

The remarks came hours after the U.S. started blocking ships from entering or exiting Iranian ports in the Strait of Hormuz, in what President Donald Trump says is an attempt to pressure Tehran’s leaders back to the negotiating table.

The blockade was announced shortly after U.S. negotiators departed from peace talks in Islamabad without securing a deal to end the war.
