Iran's Foreign Ministry spokesperson said on Monday that the United States lacked the political will for the revival of the 2015 nuclear deal.
"We do not do talks for the sake of talks. Iran is ready for the revival of the 2015 nuclear deal, but it seems Washington does not have the political will," ministry spokesperson Nasser Kanaani said in televised news conference.
Kanaani's remarks come amid on-off talks that have been underway since April 2021 to revive the deal that gave Iran much-needed sanctions relief in return for curbs on its nuclear program, AFP said.
The landmark Vienna deal has been in tatters since then US president Donald Trump withdrew from it in 2018 and Iran later backed away from its own commitments.
In a rare concession, Iran allowed a detained Iranian-American to leave the country and released his son from detention.
Tehran later said that, following the prisoner's release, it was awaiting the unfreezing of about $7 billion in funds held abroad, but Washington denied the two issues were linked.
The European Union had submitted in August a final draft of the text for the agreement, but there remain key sticking points between Tehran and Washington as well as the UN nuclear watchdog.
