US President Joe Biden told the United Nations General Assembly on Tuesday that the United States would return to the Iranian nuclear deal in "full" if Tehran does the same.
He said the United States was "working" with China, France, Russia, Britain and Germany to "engage Iran diplomatically and to seek a return to" the Joint Comprehensive Plan of Action, which America left in 2018.
"We're prepared to return to full compliance if Iran does the same," he added.
Earlier, Iran's new ultraconservative president voiced support Tuesday in his international debut for reviving a nuclear accord even as he berated the United States, hailing what he described as its failures.
President Ebrahim Raisi called on the United States to fulfill its promises to end sanctions under the 2015 nuclear accord.
"The Islamic Republic considers useful talks whose ultimate outcome is the lifting of all oppressive sanctions," Raisi said in a recorded speech to the UN General Assembly.
Raisi repeated the clerical state's stance that nuclear weapons are religiously prohibited, a position that has been met with skepticism notably by Israel, which has carried out a sabotage campaign to delay Iran's nuclear work.
Nuclear weapons "have no place in our defense doctrine and deterrence policy," Raisi said.
