The US envoy to Iran said on Friday that Tehran was approaching the point of no return for reviving a nuclear deal after it boosted its stocks of enriched uranium before talks resume this month.
Robert Malley said Iran risked making it “impossible” to gain any benefit from resuming the agreement, which has been on hold since former president Donald Trump withdrew from it in 2018.
This week, with Iran set for talks with world powers in Vienna, Austria, on November 29, the International Atomic Energy Agency said Tehran had again increased its stockpile of highly enriched uranium.
“The time will come if Iran continues at this pace with the advancements they've made, [it] will make it impossible even if we were going to go back to the [deal] to recapture the benefits,” Mr Malley told the Manama Dialogue conference in Bahrain.
The nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), was struck in 2015 and involved Iran agreeing to limits on its nuclear activities in return for an easing of sanctions.
“Iran's advances are spreading alarm across the region … that's what's making the clock tick faster and making all of us say that the time is short for a return to the JCPOA,” Mr Malley said.
Mr Malley said the US shared a “commonality of purpose” with rivals Russia and China “because we want to avoid that crisis, all of us — the crisis that would be sparked if Iran continues on its current path".
“And I want to be clear, because there's no ambiguity about what they seem to be doing now, which is to drag their feet on the nuclear talks and accelerate the progress in their nuclear programme.”
The US envoy said he was not encouraged by the statements from the new government of Iranian President Ebrahim Raisi, which earlier on Friday accused Washington of conducting a “propaganda campaign” against the country.
“If they stick to their public pronouncements, unfortunately we're not headed in the right direction … but let's wait to see what happens,” Mr Malley said, pledging that US President Joe Biden would honour a revived deal.
“Our intent, our clear intent in coming back into the deal is to stick with the deal because we don't want to see a nuclear crisis,” he said.
Iran had reacted angrily to a US pledge to take its Gulf Arab allies' interests into account in any revived deal.
“The US government, which is responsible for the current situation after withdrawing from the nuclear deal, is once again trying to provoke a crisis,” foreign ministry spokesman Saeed Khatibzadeh said.
