It remains unclear if Iran and world powers will be able to overcome the deep mistrust that resulted from the Trump administration's withdrawal from the agreement. Numerous other sanctions remain in place, however.
It was not immediately clear if Iran would be willing to attend.
Iranian President Hassan Rouhani said Thursday that he hoped the Biden administration would come into compliance with the deal and lift the sanctions imposed on his country, according to Iranian state TV.
He said Iran would cease to adhere to the so-called Additional Protocol, an arrangement that provides the IAEA broad access and information regarding Iran's nuclear program, including both declared and undeclared facilities.

Earlier on Thursday, the E3, the three European participants in the deal, and the United States released a joint statement warning Iran against going through with that step.
Biden faces a tough task in Congress to build support for the Iran deal, which was never popular with Republicans and some Democrats.
This would involve Washington revoking Trump's 2018 withdrawal and green-lighting an Iranian request for an emergency International Monetary Fund loan, while Iran freezes "the most problematic aspects" of its nuclear programme, he said.
"The E3 and the United States affirmed their shared objective of Iran's return to full compliance with its commitments under the JCPOA", the statement said.
The diplomat, who spoke on condition of anonymity, added that the suspension of the implementation of the additional protocol "does not mean that the inspectors of the International Atomic Energy Agency should leave Iran", because they would be able to stay under the nuclear deal.
Iran is "playing with fire", said German Foreign Minister Heiko Maas, who took part in the talks Thursday in Paris with his British and French counterparts.
The diplomats noted "the unsafe nature of a decision to limit IAEA access, and urge Iran to consider the consequences of such grave action, particularly at this time of renewed diplomatic opportunity".
The UN nuclear watchdog said last week that Iran had started producing uranium metal in a new violation of the accord, prompting the European powers to warn that Tehran was "undermining the opportunity for renewed diplomacy".
The chancellor also said that "now was the time for positive signals that create trust and increase the chances of a diplomatic solution", he added.
The 2015 accord is aimed at preventing Iran from developing nuclear weapons. Tehran denies it is seeking such an arsenal.
Iran began breaching the deal in 2019 in response to a United States withdrawal from the deal under then-president Donald Trump, and has been locked in a standoff with Biden's administration over who should move first to save the accord.
However the meeting in Paris did not appear to offer any concession to Iran and Iranian Foreign Minister Mohammad Javad Zarif appeared unimpressed.
It's also reversed the Trump administration's determination that all U.N. sanctions against Iran had been restored and eased stringent restrictions on the domestic U.S.travel of Iranian diplomats posted to the United Nations.
