Takht-Ravanchi told the BBC that Tehran was ready to discuss curbs on its nuclear program, including measures related to its roughly 400 kg stockpile of highly enriched uranium, if Washington was willing to lift sanctions.
“If they are ready to talk about sanctions, we are ready to discuss this and other issues related to our nuclear program,” he said, adding that it was too early to say what specific steps might emerge from negotiations.
Iran’s atomic energy chief said on Monday that Tehran could dilute its most highly enriched uranium in exchange for the removal of all financial sanctions, a point Takht-Ravanchi cited as an example of Iran’s flexibility.
However, he repeated that the idea of ending all uranium enrichment in Iran – a longstanding US position and a major sticking point in past talks – would not be accepted.
“The issue of zero enrichment is no longer raised and, as far as Iran is concerned, is not on the negotiating table,” he said.
Indirect talks between Tehran and Washington resumed in Oman earlier this month, with a second round scheduled for Tuesday in Geneva, Takht-Ravanchi confirmed.
“(Initial talks went) more or less in a positive direction, but it is too early to judge,” he said.
A US delegation including envoys Steve Witkoff and Jared Kushner is expected to meet Iranian officials in Geneva, with Omani representatives mediating.
Takht-Ravanchi said the “ball is in the US court” to demonstrate it is serious about reaching an agreement, adding that Washington had publicly and privately, through Oman, expressed interest in a peaceful resolution.
While Tehran has signaled readiness to negotiate limits on its nuclear activities in return for sanctions relief, it has repeatedly ruled out discussions on its ballistic missile program. Takht-Ravanchi reaffirmed that position, saying Iran would not deprive itself of what it considers defensive capabilities.
“When we were attacked by the Israelis and the Americans, our missiles came to our help. So how can we accept depriving ourselves of our defensive capabilities?” he said.
Iran has also rejected linking the nuclear talks to its regional policies, including support for allied armed groups, an issue increasingly raised in US political discourse around the negotiations.
