IRNA � Iranian foreign minister and the European Union (EU) foreign policy chief on Friday morning discussed implementation of the nuclear deal reached between Iran and world powers in 2015.

Mohammad Javad Zarif and Federica Mogherini, attending a working breakfast on Friday morning, discussed the future of Iranian nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA) following the US unilateral withdrawal from the deal.

Zarif and Mogherini met in Vienna's Palais Coburg Hotel, hours before the start of another meeting of the JCPOA Joint Commission which is going to be held there, with the presence of foreign ministers of 5 countries (UK, France, Russia, China plus Germany).

Speaking to reporters upon arrival in Vienna early Friday, Zarif urged the European Union to guarantee the rights of Iranian nation enshrined in the nuclear deal.

He referred to Washington unilateral withdrawal from the nuclear deal and said that following the return of parts of anti-Iranian sanctions after the US's illegal action, Tehran expects other sides of the JCPOA to compensate it.

Zarif left for Vienna late Thursday to take part in the meeting of foreign ministers of JCPOA members.

The meeting is to be held on Friday under presidency of Mogherini.

The foreign ministers of Iran, Germany, France, Russia, UK and China will attend the meeting.

This is the second meeting after US unilateral exit from JCPOA which is slated to discuss EU�s economic proposal with the aim of ensuring Iran�s economic and commercial interests in the absence of US from the international pact.

Expert meeting of Iran and 4+1 Group was held late Thursday.

US President Donald Trump announced on May 8 that Washington was walking away from the nuclear agreement.

Trump also said he would reinstate US nuclear sanctions on Iran and impose �the highest level� of economic bans on the Islamic Republic.

Under the JCPOA, Iran undertook to put limits on its nuclear program in exchange for the removal of nuclear-related sanctions imposed against Tehran.
