Iran has ruled out transferring its enriched uranium abroad, telling Pakistan Army Chief Asim Munir that negotiations with the United States cannot resume until Washington meets Tehran’s demands.

Iran’s security chief Mohsen Rezaei conveyed the message during his meeting with Munir, who is visiting Tehran as part of Pakistan’s renewed efforts to broker a peace deal between Iran and the US. Rezaei, secretary of Iran’s Supreme National Security Council, said the nuclear material “constitutes a major asset and national wealth for the Iranian people,” AFP reported.

Rezaei said Tehran would not engage in dialogue with Washington until it takes steps to restore trust. “There will be no negotiations until America takes steps to build trust -- a process that must begin with the fulfilment of Iran's conditions.”

He added that Iran remained deeply suspicious of US intentions. “Today, our nation does not trust America. It believes that if we enter the negotiations, they (the Americans) will attack us again.”

Iran has repeatedly insisted that ceasefire negotiations can begin only after Washington accepts its demands. These include ending the US blockade on Iranian ports, lifting all sanctions on its oil exports and ending hostilities across all fronts.

Munir, on his fifth visit to Iran since June, met the country’s top leadership on Tuesday to discuss efforts to reduce tensions in West Asia. Pakistan’s Interior Minister Mohsin Naqvi accompanied him.

According to Iranian state television, Munir met President Masoud Pezeshkian and Parliament Speaker Mohammad Bagher Ghalibaf, one of Tehran’s key negotiators.

Ghalibaf echoed Rezaei’s concerns over Washington’s credibility, accusing the US of violating the ceasefire agreement reached in June. He said Washington must fulfil Iran’s seven conditions and stressed that threats would not change Tehran’s strategic decisions, news agency PTI reported.

The diplomatic deadlock comes days after reports suggested that US officials were considering using the country’s largest non-nuclear bomb, known as the “mother of all bombs”, against Iran if President Donald Trump orders renewed military operations.

The conflict began with US-Israeli strikes on Iran and has continued for eight months. Both sides agreed to a ceasefire framework in June, but it unravelled within a month over disputes involving navigation through the Strait of Hormuz and Iran’s nuclear programme.

Trump had cited Iran’s nuclear ambitions as one of the reasons for launching military operations. Washington continues to demand a complete halt to Iran’s nuclear programme while using economic sanctions to pressure Tehran. Iran has refused to surrender its enriched uranium while denying that it seeks to develop nuclear weapons.
