Ali Khezrian made the announcement in a tweet while reacting to Trump’s announcement about triggering the snapback mechanism against Iran, Mehr News Agency (MNA) reported.

US failed at the United Nations Security Council to approve its resolution on extending an expiring arms embargo against Iran upon the JCPOA. Without being reinstated by the UNSC, the sanctions are set to be expired in October.

The UN Security Council on Friday resoundingly defeated the US resolution, leaving it far short of the minimum nine “yes” votes required for adoption. Eleven members abstained, including France, Germany and Britain, while the US and the Dominican Republic were the only yes votes. China and Russia strongly opposed the resolution, but didn’t need to use their vetoes.

“The US administration, one of the violators of the JCPOA, is to trigger the snapback mechanism. While remaining in the JCPOA in case of returning the UNSC resolutions will bring no more benefits for Iran, I put forward the double-urgency bill on ‘Iran’s automatic withdrawal from the JCPOA in case of activation of the snapback mechanism’,” Khezrian posted on his Twitter.

Iran can quit the JCPOA based on Paragraph 36 of the nuclear deal which reads: “If Iran believed that any or all of the E3/EU+3 were not meeting their commitments under this JCPOA, Iran could refer the issue to the Joint Commission for resolution; …If the issue still has not been resolved to the satisfaction of the complaining participant, and if the complaining participant deems the issue to constitute significant non-performance, then that participant could treat the unresolved issue as grounds to cease performing its commitments under this JCPOA in whole or in part and/or notify the UN Security Council that it believes the issue constitutes significant non-performance.“

US President Trump has said the United States will try to trigger a “snapback” of sanctions on Iran at the United Nations next week.

“We’ll be doing a snapback,” Trump told reporters on August 15, the day after the UN Security Council rejected a US-sponsored resolution to extend an arms embargo on Iran. “You’ll be watching it next week.”

However, Iranian FM Mohammad Javad Zarif highlighted that the US claim of its ability to trigger the snapback mechanism of the JCPOA is baseless.

“@AmbJohnBolton has repeated today what he said on May 8, 2018, while National Security Advisor in the Trump administration,” Zarif tweeted early on August 17, referring to an Op-ed by former US National Security Advisor John Bolton who notes that JCPOA supporters are ‘right’ about the fact that “Washington has no standing to invoke its [JCPOA’s] provisions” since it has withdrawn from the deal.

Iran and other signatories of the deal note that Washington cannot legally do so as it has officially ‘ceased participation’ in the deal in May 2018 and has not attended the sessions of the JCPOA Commission afterward.

Chinese Foreign Ministry spokesman Zhao Lijian said in a gathering in Beijing on Monday that the failure of the US resolution “again showed that unilateralism has no popular support, and hegemonic behavior will not succeed”.

The United States needed to end its unilateral sanctions and adopt a rational attitude, returning to the “correct path” of respecting the Iran nuclear agreement and Security Council decisions, Zhao added.
