Iran said Wednesday it would "automatically" return to its nuclear commitments if US President-elect Joe Biden lifts sanctions.
Tehran again meeting its commitments "can be done automatically and needs no conditions or even negotiations," Foreign Minister Mohammad Javad Zarif said in comments published in the state-run Iran daily.
Once in the White House, Biden could "lift all of these (sanctions) with three executive orders," Zarif argued.
If Biden's administration does so, Iran's return to nuclear commitments will be "quick", the minister added, AFP reported.
Washington's return to the deal, however, could wait, Zarif added.
"The next stage that will need negotiating is America's return... which is not a priority," he noted, adding that "the first priority is America ending its law-breaking".
Zarif said that although outgoing US President Donald Trump pulled the US out of the JCPOA, he did not withdraw the country from the UN and thus must carry out the decisions of the UN Security Council.
"As a UN member and a permanent member of the UN Security Council, the US is duty-bound to implement Resolution 2231," Zarif stressed.
For his part, Iranian President Hassan Rouhani called the Trump administration "unruly", and said a Biden administration could "bring back the atmosphere" that prevailed in 2015 at the time of the nuclear deal.
