"Iran started reducing its obligations last May, but we are still open to any initiative that can ensure for Iran benefits from the JCPOA," Araghchi told reporters.
He added that the nuclear deal was "still alive" despite pressure from the United States, which withdrew from the agreement in 2018.
Earlier in the month, Iranian President Hassan Rouhani stated that Tehran will only sit down with Washington if the US returns to the 2015 Iran nuclear deal and scraps sanctions against the Islamic Republic.
On Iran's Economy Amid Decrease in Oil Export
The Iranian economy is functioning normally despite the decrease in oil export due to Washington's sanctions, Deputy Foreign Minister Abbas Araghchi said on Wednesday.
"Everything is normal. Our economy is feeling good. For the first time in our modern history, it continues development without using oil. And this is thanks to the US sanctions," Araghchi told reporters.
Washington has also vowed to drive Iran's oil exports down to zero and demanded that other countries stop any such purchases.
