“Just finished chairing #JCPOA Joint Commission,” Schmid wrote on her Twitter account.

“Important to see that participants are united in resolve to preserve the #IranDeal and find a way to ensure full implementation of the agreement despite current challenges,” she added.

The JCPOA Joint Commission meeting was held on Tuesday at 11:00 local time in Vienna at the level of deputy foreign ministers and directors general of foreign ministries of the participant states, IRNA reported.

Iran was represented to the meeting by Seyyed Abbas Araqchi who arrived in Vienna on Monday.

He has so far held separate bilateral meetings with other participants of the meeting and is scheduled to exchange views with Director-General of the International Atomic Energy Agency (IAEA) Rafael Mariano Grossi.

Araqchi has earlier said that the meeting of JCPOA Joint Commission was significant regarding to the US attempts to restore UN previous sanctions to annihilate the JCPOA.

Referring to the fact that the UNSC members have opposed the US draft resolution to invoke snapback clause of the JCPOA, Araqchi said the US attempts will definitely be an important discussion in the meeting.

The US has illegally called for the reinstatement of UN Security Council sanctions against Iran. US Secretary of State Mike Pompeo announced on Thursday that Washington will return all UN sanctions against Iran “at midnight Sep. 1,” a claim which was strongly condemned by other signatories of the nuclear deal including the EU, Russia and China and was mocked by Iranian senior officials.

Zarif reacted to US claims on returning unilateral sanctions against Iran by saying in a tweeted message, “Obviously they don’t understand law or UN. Maybe they can grasp this: You divorced the JCPOA in 2018. Your name on the marriage certificate is irrelevant.”

Washington withdrew from the JCPOA in May 2018 and reinstated its unilateral economic sanctions against Iran in defiance of Resolution 2231.

Now after more than two years, the Trump administration is seeking to trigger the snapback of sanctions at the UN by claiming that it remains a member of the JCPOA.

The United States’ most prominent Western allies have refused to fall into step with the push, which followed Washington’s humiliating defeat in securing an extension of the UN arms embargo against Iran at the UNSC.

Only the Dominican Republic voted ‘yes’ to Washington’s resolution calling for the extension of the embargo beyond October 18.

The president of the Security Council on August 25 dismissed attempts by the US to reinstate all UN sanctions against Iran due to a lack of consensus in the 15-member body.
