The president said during a televised cabinet speech on Wednesday if the new US government places a signature to implement commitments under the United Nations Security Council resolution 2231 – which underpins Iran’s nuclear deal – it will see a signature from Iran.
A "tyrant's era came to an end and today is the final day of his ominous reign," Rouhani said 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."
“If they issue an order, they will see an order issued in Iran, no more. If they effectively implement their commitments, they must know there will be effective implementation of commitments on this side,” Rouhani said.
He said Iran expects the new occupants of the White House to try to “remove all the stains of the past four years, that is if they can be removed”.
“If they show their honesty in action, toward the laws and the resolution that they voted for and commitments they signed on for, naturally we will also implement all our commitments.”
During his presidency, Trump led a campaign of "maximum pressure" against Iran, pulling Washington out of a landmark nuclear deal with Tehran in 2018 and reimposing illegal sanctions.
