The Iranian government said that it had made its decision on the Vienna talks, and that it was time for the other parties to make the necessary decisions.
On the other hand, US Secretary of State Anthony Blinken said that there are still fundamental differences with Tehran.
Iranian government spokesman Ali Rabiei stressed that everything that should be negotiated in Vienna has been discussed, and all parties must take their decision, noting that his country has made its decision regarding these talks.
Rabiei made it clear that the outcome of the negotiations in Vienna cannot be predicted, and that there will be consensus on all points.
The Iranian official confirmed that there was an agreement in the Vienna talks to lift sanctions on key sectors of the country's economy.
For his part, US Secretary of State Anthony Blinken said that they have overcome obstacles in the indirect talks with Iran, but there are still some fundamental differences.
In response to a question about what his country expects from the new Iranian President Ebrahim Raisi - at the negotiating table in Vienna on the Iranian nuclear program - Blinken said, "In Iran, decisions are made by Supreme Leader Ali Khamenei."
Blinken added: The ball is now in Iran's hands after 6 rounds of indirect talks in Vienna, and we will see what it will decide, and we do not know if the Iranian leader is ready to do what is necessary to return to full compliance with the nuclear agreement.
