The 60-day deadline set under the memorandum of understanding between the United States and Iran for negotiations has expired.
Iran has rejected the existence of any such deadline, saying the memorandum did not include a condition requiring Tehran to conclude negotiations within 60 days.
Iranian Foreign Ministry spokesman Esmail Baghaei said Iran does not make decisions under pressure from deadlines or ultimatums.
Baghaei said the 60-day period mentioned in the Islamabad memorandum was related to negotiations on lifting sanctions and resolving the nuclear issue.
He further said talks did not even begin because the United States violated the memorandum.
The Iranian spokesman also said Pakistan and Qatar were continuing efforts to reduce tensions between Iran and the United States. He said there were no other mediators involved in the process.
Baghaei blamed what he described as illegal US actions for insecurity in the Strait of Hormuz.
He added that Iran was working with Oman on mechanisms to ensure safe navigation and shipping through the strategic waterway.
The remarks come as tensions between Tehran and Washington remain high, with diplomatic efforts continuing to prevent further escalation in the region.
