June 8, The Iran Project - The Joint Commission of Iran and five signatories of the nuclear deal began its meeting in Tehran at the expert level on Thursday (June 7) morning aimed at devising a mechanism for implementing the Joint Comprehensive Plan of Action (JCPOA), also known as Iranian nuclear deal, without the US between Iran and the European countries.

The last expert meeting of the Joint Commission a was held prior to the meeting of deputy foreign ministers of the remaining signatories in Vienna two weeks ago on May 25.

On Thursday, delegates from Iran and other parties to the deal � Russia, China, France, Britain and Germany � held discussions behind closed doors in the Iranian capital over the future of the now six-party agreement.�European Union experts were also taking part in the negotiations.

According to the ISNA news agency, the participants in Thursday�s talks sought to work out a mechanism to both go ahead with the deal�s implementation without the US and help Iran collect all the economic dividends of the JCPOA when the American bans return.

On the same day, the Iranian foreign minister written a letter to his counterparts on the unlawful withdrawal of the US from the 2015 nuclear deal, saying that for the accord to stay alive, the remaining signatories need to guarantee that Iran will be �unconditionally� compensated with the return of American sanctions.

Also, Mohammad Javad Zarif published a copy of the letter on his Twitter account on Thursday, calling for action in the face of Washington�s �ever-expanding economic bullying,� which poses a threat to �not just the accord, but multilateralism and the rule of law.�

The letter comes amid efforts by Tehran and its partners in the 2015 deal � France, Britain, Germany, Russia and China � to keep the agreement in place after US President Donald Trump announced last month that Washington was walking out and slapping the nuclear-related sanctions back on Iran.

In a meantime, the Ministers of Foreign Affairs and Finance from the UK, Germany, and France have written to top US officials, that they confirm their commitment to JCPOA, urging Washington to spare European business from secondary sanctions.

The politicians want to allow European enterprises to collaborate with Tehran, first of all, in such branches as pharmaceuticals, healthcare, power industry, civil aviation, infrastructure, and banking sphere.

�An Iranian withdrawal from the (nuclear agreement) would further unsettle a region where additional conflicts would be disastrous,� the ministers stress in the joint letter, dated June 4, addressed to the US Secretary of State Mike Pompeo and the US Treasury Secretary Steven Mnuchin.
