Tehran, June 7, IRNA - The heads of diplomatic delegations negotiating the revival of the 2015 Iran nuclear deal have returned to the capitals of their countries to hold consultations on final decisions.

Iran newspaper published a memo on Monday that the fifth round of the Joint Commission meetings of the Joint Comprehensive Plan of Action (JCPOA) was held in Vienna, Austria, where top diplomats of delegations decided to travel back to their capitals in order to hold consultations with their governments.

Top negotiators of signatories to the JCPOA, including the P4+1 group (the UK, France, Russia, China plus Germany) and Iran as well as the European Union, evaluated the latest round of talks, saying that all sides are determined to find ways to solve the remaining issues in the coming days.

Abbas Araghchi, the Iranian top nuclear negotiator, said after the Wednesday session that a good progress has been made in this round of talks, but there are disagreements on key issues. In an interview with Press TV, he noted that the other side should take difficult decisions, because it is the time for the Americans and the Europeans to decide, and we hope that they can do it.

Referring to the possibility that the next round of talks can be the final one, Araghchi said that in a diplomatic negotiation, nothing can be predicted.

Iran's Minister of Foreign Affairs Mohammad Javad Zarif wrote on his Twitter account on June 4, "Agreed in phone call with FM @DominicRaab on need to resume full compliance with the JCPOA. Underlined that US must return fully to its obligations & cease trying to use unlawful economic war against Iran as negotiating leverage. Also discussed bilateral & consular issues."

Mikhail Ulyanov, Russian Ambassador and Permanent Representative to the International Organizations in Vienna, also wrote on his Twitter account on June 5, "The restoration of the #JCPOA may have a positive effect on the situation in #PersianGulf and open the way to direct talks between regional states on regional security issues with due account of the existing initiatives including Russian concept of collective security in the area."

The Virginia-based journalism company The Politico has recently reported, "Negotiators have produced at least 20 pages of text with various options on how to solve the remaining hurdles."

Differences on access to Iran's advanced centrifuges, equipment for uranium enrichment as well as inspections by the International Atomic Energy Agency's inspectors are among the issues that should be solved to pave the ground for reviving the JCPOA, The Politico mentioned, adding that the lifting of sanctions is another important issues in the way of reaching an agreement in Vienna.
