Sources familiar with the matter told the Fars and Tasnim news agencies that Pezeshkian on Monday gave the green light for talks to begin.
The timing and location of the negotiations were not immediately known.
Follow-up reporting by Tasnim suggested that the details of the negotiations have not yet been finalized and that once the overall framework of the talks takes shape, further information will be provided.
Talks between Tehran and Washington, mediated by Oman, collapsed last June after the United States joined the Israeli regime in its military aggression against the country, which included attacks on Iranian nuclear sites.
Meanwhile, ISNA reported that the Iranian and American delegations were expected to meet for talks within the next few days.
As in the previous rounds, Iranian Foreign Minister Abbas Araghchi and US President Donald Trump's senior envoy Steve Witkoff will lead the potential talks. Deputy foreign ministers Majid Takht-Ravanchi and Kazem Gharibabadi will accompany the top Iranian diplomat.
According to some sources, following Araghchi's trip to Turkey on Friday and Ankara's efforts to host Tehran-Washington talks, negotiations might be held in Turkey, potentially involving Turkish Foreign Minister Hakan Fidan.
In addition to Turkey, Qatar and Egypt have also made diplomatic efforts to host the talks, as part of efforts to prevent the United States from launching a new act of aggression against Iran.
Iranian officials have made it clear that any attack by the United States or Israel would be met with an immediate and powerful response and could spark a regional war.
President Trump has ordered a massive military buildup in the Persian Gulf but has shifted his rhetoric, from threatening a strike and backing rioters who wrought havoc in Iranian cities earlier this month, to calling for a deal with Iran.
The US president claimed on Sunday that Iranian officials were “seriously talking to us” without providing further details, and that “hopefully, we’ll make a deal.”
During his first term in office, Trump withdrew the US from a UN-endorsed nuclear deal with Iran, called the Joint Comprehensive Plan of Action (JCPOA), and re-imposed tough economic sanctions on Tehran.
Iranian Foreign Ministry spokesman Esmaeil Baghaei told reporters on Monday that Tehran should first evaluate the different aspects of talks with the US.
He said various points have been exchanged within this framework, and Iran is currently “in the stage of reviewing and deciding on the details of a diplomatic process.”
He expressed hope that the efforts would yield results in the future and that the framework of negotiations would be determined.
Speaking in an interview with CNN on Sunday, the Iranian foreign minister said the United States must seize the chance to reach a fair deal with Tehran, warning that any military aggression would be a “disaster” for the entire region.
The US side also projected optimism over the weekend. Speaking to reporters aboard Air Force One on Saturday, US President Donald Trump said that Iran was “talking to us, seriously talking to us.”
Iran will not transfer its enriched nuclear material: SNSC official
Deputy for Foreign Policy at the Secretariat of Iran’s Supreme National Security Council Ali Bagheri Kani said the country’s enriched nuclear material will not be transferred to any country.
Iranian officials have no intention of transferring enriched nuclear material to any country, and possible negotiations with the US are not centered on such a matter at all, he added.
Israeli media have reported that Turkey has allegedly offered to take custody of Iran's stockpile of enriched uranium as part of diplomatic efforts to prevent a potential US military attack on Iran.
A senior Turkish official told Haaretz that Istanbul is likely to propose transferring Iran’s enriched uranium to Turkey. The proposal targets approximately 440 kilograms of uranium enriched to 60 percent purity, along with other stockpiles.
