The E3 - France, Germany and the United Kingdom - last month triggered a mechanism in a 2015 international nuclear deal with Iran to "snapback" international sanctions within 30 days if Tehran does not convince them of its compliance.
“Iran made a new offer to E3 yesterday to avoid snapback, I understand. One which frankly is barely a bit credible. I am not alone in thinking that,” Norman posted on X, going on to cite a source familiar with the matter.
"The E3 regard Iran's latest proposal as insufficient in substance as it demands far-reaching actions like extension of the SnapBack or even complete termination (of 2231) in exchange for Iranian declarations of intent, but without any concrete actions on the Iranian side," he quoted the source as saying.
Norman was referring to the United Nations Security Council resolution number promulgating the nuclear deal which, in the Western view, authorizes the snapback move.
Iran denies seeking a bomb, criticized the US withdrawal from the agreement during President Donald Trump's first term in 2018 and say the European powers lack authority to trigger snapback sanctions because they violated their own commitments to the deal.
