"The president has made clear that he believes that through follow-on diplomacy, the United States seeks to lengthen and strengthen nuclear constraints on Iran and address other issues of concern".
Addressing a Cabinet meeting January 20, Rouhani said that "the ball is now in Washington's court" to abide by its obligations under the 2015 accord from which Trump walked away in May 2018, reinstating a set of onerous economic sanctions against the Islamic Republic.
A "tyrant's era came to an end and today is the final day of his ominous reign", Iranian President Hassan Rouhani said earlier in televised remarks to his cabinet.
"Someone for whom all of his four years bore no fruit other than injustice and corruption and causing problems for his own people and the world". The Trump administration has repeatedly placed sanctions on Iran, which the country has called an unfair targeting of the country and a means of punishing them financially and economically, especially during a global pandemic.
The Iran deal, "for whatever its limitations, was succeeding on its own terms in blocking Iran's pathways to producing fissile material for a nuclear weapon on short order", he said.
Referring to the failure of the policy of maximum pressure, Zarif noted that the Iranian people resisted the pressure and through this resistance and diplomacy Iran was able to stand its ground against the United States on worldwide forums.
The sanctions targeted Iran's vital oil sales and worldwide banking ties, plunging its economy into a deep recession.
Mr Biden appears to see a return to the deal as a prelude to wider talks on Iran's nuclear work, its ballistic missiles and regional activities.
Blinken confirmed Biden's desire for Washington to return to the nuclear agreement, but said that was conditional on Tehran's return to strict compliance with its commitments.
Iran's Foreign Minister Mohammad Javad Zarif on Wednesday expressed relief over the departure of Donald Trump from the White House.
"If they return to the law, our response will be positive as well".
"If Iran comes back into compliance, we would too", Biden's pick for secretary of state Tony Blinken told the Senate Foreign Relations Committee on Tuesday. It has said it will then return to full compliance.
