TEHRAN – In the third day of talks in Vienna intended to restore the 2015 nuclear deal, Iran’s chief negotiator held talks with European Union’s Enrique Mora, who acts as a coordinator.The third day of talks between experts from Iran and the EU centered around technical and legal matters regarding the Safeguards agreement between Iran and the International Atomic Energy Agency (IAEA).Delegates from Iran, the EU and the U.S.

resumed talks in Vienna on Thursday after nearly a five-month hiatus.

This round of talks started on Thursday without the presence of nuclear negotiators from the European trio – Germany, France and Britain.

Only experts from these three countries have attended the negotiations.

 Iran believes that any agreement on restoring the nuclear deal, officially called the Joint Comprehensive Plan of Action (JCPOA), is dependent on putting an end to unsubstantiated allegations about Iran’s past nuclear program.

Iran insists that these questions had already been resolved within the PMD, when the nuclear deal was signed in July 2015.According to reports, substantial progress has been made in bringing the views of Iran and the U.S.

closer together during the last three days.

However, in Tehran’s view nothing is resolved until everything is settled.Behrouz Kamalvandi, the spokesman for the Atomic Energy Organization of Iran (AEOI), also confirmed on Saturday that talks are mainly focused on Safeguards issues.“We are now negotiating,” Kamalvandi said of the talks between Iran’s nuclear experts with Mora.On the atmosphere of the talks, he said, “It is not bad.”Mohammad Marandi, a senior expert on nuclear issues, also told Al-Mayadeen TV that “progresses” have been made in Vienna, but one should be “cautious”.

He argued the success of talks is 50 percent.

Marandi said the differences remain only between Iran and the United States.He added, “We have heard from certain European sources that the Americans have revived their views on certain issues.”The Russian chief negotiator in the Vienna talks, Mikhail Ulyanov, also tweeted that there is “no unresolvable issue” on the table in the Vienna talks.
