Foreign Ministry spokesman Esmaeil Baghaei said on Monday that following consultations, preparations are underway for the next round of indirect talks on Sunday.
Since April, Tehran and Washington have held five rounds of indirect negotiations over Iran’s nuclear program.
Three rounds of the two countries’ negotiations were held in Muscat, while the remaining two rounds were held in the Italian capital, Rome.
The negotiations were marked by repeated shifts in US stances, which prompted Iranian officials to criticize the “contradictory” statements made by their American counterparts.
Since April, Iran and the United States have held five rounds of indirect talks, mediated by Oman, on a replacement for the 2015 nuclear deal, which was derailed by the American withdrawal in 2018.
However, the talks have faced an obstacle over the US demand for Iran to stop enriching uranium under any new deal.
Iran says it will not forgo its right to uranium enrichment, which is guaranteed under the Non-Proliferation Treaty, the NPT.
In its latest report, the International Atomic Energy Agency (IAEA) claimed that Iran has sharply increased its stockpile of uranium enriched to up to 60 percent, close to the roughly 90 percent level needed for atomic weapons.
In its quarterly report, the agency said that as of May 17, Iran possesses an estimated 408.6 kilograms of uranium enriched up to 60 percent, marking an increase of 133.8 kilograms since the previous report in February.
Iran’s Foreign Ministry and the Atomic Energy Organization of Iran (AEOI) issued a joint statement last week, denouncing it as a "political" and unbalanced report by the United Nations nuclear watchdog and said it has been drafted under European pressure.
