Iran's foreign minister Abbas Araqchi said uranium enrichment is non-negotiable after US special envoy to the Middle East Steve Witkoff suggested any new nuclear deal would require a halt.
"We are open to acknowledging and answering concerns [about our nuclear programme] in order to help build trust," Araqchi told reporters in Tehran. "But the core issue of Iran enriching uranium is not up for negotiation."
Araqchi was responding to questions about a social media post made by Witkoff on 15 April in which he suggested that any new nuclear deal would require Iran to "stop and eliminate" its enrichment of uranium. In a television interview the day before, Witkoff indicated that Washington just wanted Iran to abide by the 3.67pc enrichment threshold that was agreed in the previous nuclear deal that US president Donald Trump pulled out of in 2018.
Witkoff's apparent shift in stance was echoed by White House press secretary Karoline Leavitt on 15 April, who said: "The president does not want to see Iran have a nuclear programme. He does not want Iran to obtain a nuclear weapon."
Araqchi, who is leading the Iranian delegation in the talks, said such "contradictory" comments by US officials are "not helpful".
Aracqhi and Witkoff are due to meet on 19 April for a second round of talks, which were initially scheduled to be held in Oman but and now due to take place in Rome, according to Iran's state broadcaster IRIB.
Both Tehran and Washington described the first round of talks in Oman on 12 April as "positive and constructive."
