MNA – Vienna will be on the spotlight again with Iran and 5+1 slated to hold a joint commission to address famous deal JCPOA.Vienna’s Palais Coburg will host the event, where Iran’s negotiators Seyyed Abbas Araghchi will represent Iran and form the EU, Federica Mogherini and from the US, Helga Schmid will chair the meeting on Tuesday.

On agenda will be top Foreign Minister Zarif’s letter to Mogherini earlier in December along with the JCPOA implementation. Zarif’s letter raised concerns about the US Congress’ extension of ISA (Iran Sanctions Act) which John Kerry had, only verbally, pledged to prevent the extension.

The Tuesday meeting will have also a joint statement. Before that, Iran and the US envoys will sit in a bilateral meeting. US Department of State will reportedly sent undersecretary Thomas Shanon to the meeting.

The extension of ISA had garnered huge criticism in Tehran and US was implicated with being the first to undermine JCPOA. The general mentality among the diplomats as well as statesman favored Obama’s vetoing the extension; however, he preferred to not to either sign or veto the Act, which made the act automatically the law.
