Iran’s foreign minister says Tehran’s move to feed fuel into “hundreds” more centrifuges to enrich uranium was a response to new US sanctions on entities supporting oil and petrochemical trade. 

Hossein Amir-Abdollahian said on Tuesday that “In response to the new US sanctions, we started pumping gas into hundreds of new generation centrifuges. We acted based on the decision made. The Americans shouldn’t think they can get concessions from Iran at the negotiating table with these measures.”

He described it as startling that the US proposed a resolution in the International Atomic Energy Agency while “we repeatedly received goodwill messages from US President Joe Biden through mediators.” 

On Monday, August 1, the US Treasury sanctioned several companies it said were involved in the sale of Iranian petroleum and petrochemicals.

Announcing Tehran’s latest steps beyond the limits of the 2015 Iran nuclear deal, the JCPOA (Joint Comprehensive Plan of Action), Behrouz Kamalvandi, spokesman for the Atomic Energy Organization of Iran, said on Monday that Iran has started pumping uranium gas into hundreds of IR-1s & IR-6 centrifuges as part of its plan to reach uranium enrichment capacity of at least 190,000 SWU (separative work units), a measurement of efficiency in enrichment. Under the JCPOA Iran was allowed only 6,104 SWU and no IR-6s.

Amir-Abdollahian added that Tehran is reviewing the recent proposals by the European Union to take forward talks over renewing the 2015 Iran nuclear deal. The US State Department spokesman has said Washington also is reviewing proposals made by Joseph Borrell, the European Union foreign policy chief.
