The US on Wednesday urged Iran to show "good faith" as it agreed to return to negotiations, saying Washington believed it was possible to revive a nuclear deal quickly.
Earlier, Iran's nuclear negotiator said after talks with European Union mediators in Brussels that Tehran had agreed to resume talks in Vienna next month.
State Department spokesman Ned Price said in a statement that the US believes it is still possible to "quickly reach and implement an understanding on return to mutual full compliance" with the 2015 Joint Comprehensive Plan of Action (JCPOA) as only a small number of outstanding issues remain to be settled from the last round of talks in June.
"As we have also been clear, this window will not remain open forever as Iran continues to take provocative nuclear steps, so we hope that they come to Vienna to negotiate quickly and in good faith,” Price noted.
For his part, Iran’s Deputy Foreign Minister Ali Bagheri Kani said on Twitter on Wednesday that Iran agrees "to start negotiations before the end of November" after meeting EU mediators in Brussels.
President Joe Biden has repeatedly offered to return to the nuclear accord reached in 2015 but his administration has voiced growing frustration at the prolonged delay, which comes as a new hardline government gets settled in Tehran.
In 2018, then president Donald Trump withdrew the US from the deal, opting for what he called a maximum-pressure campaign of stepped-up US sanctions.
