Iran revealed it has no plans for further negotiations with the US after JD Vance left 21 hours of talks without reaching a deal.

Tehran also warned there will be ‘no change’ in the effective blockade on the Strait of Hormuz as Iran is 'not in a hurry.'

The comments came after Vice President Vance revealed the negotiations in Pakistan's capital Islamabad had failed.

‘No program has yet been announced for the time, place, or next round of negotiations,’ Nour, the news agency of Iran’s Supreme National Security Council, said.

'We leave here with a very simple proposal: a method of understanding that is our final and best offer. We'll see if the Iranians accept it,' Vance said.

Following news that the American delegation was returning to the US, Iran said there will be no change to the Strait of Hormuz until it gets an acceptable offer, The Wall Street Journal reported.

‘Iran is not in a hurry, and until the US agrees to a reasonable deal, there will be no change in the situation of the Strait of Hormuz,’ an unnamed Iranian official told the Fars News Agency.

Peace talks between the US and Iran began on Saturday following Wednesday's fragile truce between the two countries after six weeks of conflict.

The US delegation to the peace talks was led by Vance, along with Steve Witkoff, the special envoy, and Jared Kushner, Trump's son-in-law.

The Iranian delegation was being led by Parliament Speaker Mohammad Bagher Ghalibaf. 

Iran’s Foreign Ministry spokesman, Esmail Baghaei, told state news agency IRNA the negotiations included discussions on the Strait of Hormuz, Iran’s nuclear program, compensation for damage from the US-Israeli strikes and sanctions on Iran.

However, he also said that Iran struggled to trust the US after previous rounds of nuclear talks were disrupted by confrontations with Israel.

'We have not forgotten and will not forget the bad faith and ill intentions of the United States,' he said.

While speaking to reporters outside the White House on Saturday, Trump acknowledged the 'very deep negotiations,' but seemed unbothered about the outcome.

'Regardless of what happens, we win. We've 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 regardless,' he said.

'With all of that, let's see what happens, but from my standpoint, I don't care.'

The president then took a dig at NATO, saying his next step is to open the Strait of Hormuz.

'We defeated their leaders. Their leaders are all dead. Now all we do is we'll open up the strait, even though we don't use it. Because we have a lot of other countries in the world that do use it, that are either afraid or weak or cheap,' he said.

'I don't know what it is, but we were not helped by NATO, that I can tell you.'

Vance did not elaborate on the next steps in the negotiations or address concerns over the Strait of Hormuz.

'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. So we go back to the United States, having not come to an agreement.'

Vance added: 'That is the core goal of the president of the United States. And that's what we've tried to achieve through these negotiations.' 

He said he spoke with Trump 'a half dozen times, a dozen times, over the past 21 hours' and was in contact with other US leaders during the peace talks.

'We were constantly in communication with the team because we were negotiating in good faith,' Vance said before departing Islamabad.

According to Vance, they were unable to reach an agreement because Iran would not commit to stopping its pursuit of nuclear weapons.

‘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, and we've made that as clear as we possibly could, and may have chosen not to accept our terms,' he said.

'We need to see an affirmative commitment that they will not seek a nuclear weapon, and they will not seek the tools that would enable them to quickly achieve a nuclear weapon.
