The Biden administration has restored a sanctions waiver to Iran, a senior State Department official said, as indirect talks between Washington and Tehran on returning to the 2015 nuclear agreement entered the final stretch.
The waiver, which was rescinded by the Trump administration in May 2020, had allowed Russian, Chinese and European companies to carry out non-proliferation work at Iranian nuclear sites.
The waiver was needed to allow for technical discussions that were key to the negotiations about returning to the deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), the State Department official said.
Ryan Costello, policy director at the National Iranian American Council (NIAC), a Washington, DC-based group in favour of restoring the deal, said the waivers allowed other countries to help Iran convert its nuclear facilities to bring them into compliance with the JCPOA.
That includes Iranâ€™s Arak heavy water research reactor, in particular, Costello said.
â€œI donâ€™t want to say itâ€™s a signal that [negotiations are] near the end, but I think itâ€™s a sign that thereâ€™s progress, that the US wants to show that itâ€™s making a good faith effort to restore the deal and overcome some of Iranâ€™s hesitations,â€ he told Al Jazeera.
The US and Iran have been negotiating indirectly in Vienna to revive the deal, which saw Iran scale back its nuclear programme in exchange for lifting international sanctions against its economy.
Former US President Donald Trump withdrew Washington from the accord in 2018 and started a â€œmaximum pressureâ€ campaign of sanctions against Tehran, which responded by advancing its nuclear programme well beyond the limits set by the JCPOA.
US President Joe Biden has pledged to restore the deal, but several rounds of talks in the Austrian capital have failed to secure a path back into the agreement so far.
Biden and his top aides also have warned that the window of opportunity for salvaging the deal is closing down, with Iran gaining irreversible nuclear know-how.
Earlier this week, a senior State Department official told reporters that the negotiations are entering a make-or-break phase, with only a â€œhandful of weeksâ€ left for a chance to restore the agreement.
â€œWe are in the final stretch because, as weâ€™ve said now for some time, this canâ€™t go on forever because of Iranâ€™s nuclear advances,â€ said the official, who spoke on condition of anonymity. â€œThis is not a prediction. Itâ€™s not a threat. Itâ€™s not an artificial deadline.â€
The US administration says preventing Iran from acquiring a nuclear weapon is one of its foreign policy priorities, but Tehran has denied it is seeking nuclear weapons.
The State Department official said on Friday that restoring the waiver was not a signal Washington was about to reach an understanding to return to the deal, however.
â€œAbsent this sanctions waiver, detailed technical discussions with third parties regarding disposition of stockpiles and other activities of non-proliferation value cannot take place,â€ the official said.
The waiver covered the conversion of Iranâ€™s Arak heavy water research reactor, the provision of enriched uranium for its Tehran Research Reactor, and the transfer of spent and scrap reactor fuel abroad.
Then-US Secretary of State Mike Pompeo revoked the waiver in May 2020, almost two years after Trump quit the deal.
Barbara Slavin, anÂ IranÂ expert at the Atlantic Council, said the resumption of the waiver was a positive step.
â€œItâ€™s a necessary prerequisite to restoring the JCPOA and thus a good sign that this can be accomplished,â€ she told the AFP news agency. â€œThese sanctions were among the dumbest and most counterproductive imposed by the former administration,â€ she added.
