Another round of in-person discussions between the United States and Iran could take place as early as this week, two sources with knowledge of the situation confirmed to NBC News.

A U.S. official told NBC News that engagement between the U.S. and Iran has continued and the two sides are attempting to get toward an agreement. On Sunday (April 12), Vice President JD Vance said U.S. officials were unable to reach an agreement with Iranian officials on a peace deal during negotiations between the two sides in Islamabad, Pakistan, during a press conference.

"The bad news is that we have not reached an agreement, and I think that's bad news for Iran, much more than it's bad news for the United States of America," Vance said via USA TODAY.

The vice president claimed that negotiations failed due to Iran's refusal to commit to not developing nuclear weapons now or in the future during the first face-to-face meetings between the two countries in 47 years.

"So we go back to the United States, having not come to an agreement, we've made very clear what our red lines are, what things we're willing to accommodate them on, and what things we're not willing to accommodate them on," Vance said via USA TODAY.

President Donald Trump had already claimed that the United States had won regardless of any outcome of the negotiations while speaking form the White House earlier on Saturday (April 11) before leaving for Miami, Florida.

"Regardless what happens, we win," Trump said via UDA STODAY. "We totally defeated that country. And so let's see what happens. Maybe they make a deal, maybe they don't. From the standpoint of America, we win."

Trump had previously announced a two-week ceasefire agreement hinging on the reopening of the Strait of Hormuz, which serves as a vital waterway for trade along the Persian Gulf responsible for an estimated 20% of the world's oil supply traveling through and has been blockaded by Iran in retaliation of the war, leading to a spike in gas prices. Iran agreed to reopen the Strait under the 10-point ceasefire plan, with the American government described s "workable," before Tehran officials claimed they plan to charge $2 million to pass through, which they said would be used to rebuild infrastructure damaged by the U.S. and Israel during 'Operation Epic Fury' and later closed the waterway in response to Israel's

“There are reports that Iran is charging fees to tankers going through the Hormuz Strait — They better not be and, if they are, they better stop now!” Trump said in response to the report via the New York Post.
