Iran is studying a European Union proposal for an informal meeting between current members of Tehran's 2015 nuclear deal and the United States, but has yet to respond to it, Iranian Deputy Foreign Minister Abbas Araqchi said on Saturday.
Iran and the United States have been at odds over who should take the first step to revive the 2015 accord. Iran insists the United States must first lift former President Donald Trump's sanctions while Washington says Tehran must first return to compliance with the deal.
Iranian Foreign Minister Mohammad Javad Zarif suggested earlier this month a way to overcome the U.S.-Iranian impasse over who goes first in returning to the nuclear deal, saying EU foreign policy chief Josep Borrell could "synchronize" or "choreograph" the moves.
