Referring to IAEA announcement of “detected natural uranium particles of anthropogenic origin at a location in Iran”, the U.S. representative to the IAEA maintained that “that there are possible undeclared nuclear materials present and activities ongoing in Iran still today is profoundly concerning… continued noncooperation by Iran would be unacceptable and would merit the Board’s appropriate escalation of this issue”. On Iran reducing its JCPOA commitments, she stressed that “Iran’s actions are transparent attempts at extortion that will only deepen its political and economic isolation”. The representative further noted that “the U.S. is willing to negotiate with Iran without preconditions”, adding that “to achieve relief from sanctions pressure,,, Iran must be willing to end its malign behaviour and take lasting steps that deny it any pathway to nuclear weapons”. Iran’s IAEA representative characterised the negotiation offer by the U.S. “a political gesture to shoulder off its responsibilities for the non-compliance with its international obligations” and contended that “if the U.S. is serious about entering into negotiations, it should, first, remove all re-imposed sanctions, so that the ground would be levelled”.
