VIENNA – U.S. Secretary of State John Kerry and Iranian Foreign Minister Mohammad Javad Zarif are discussing new ideas aimed at breaking the deadlock in nuclear talks between Tehran and six world powers, sources close to the talks said Friday.
The sources, who spoke on condition of anonymity, said the top Iranian and U.S. diplomats were preparing ideas that could be shown to both countries’ capitals.
“Discussions are continuing,” said a senior U.S. official, who declined to discuss details about the negotiations in Vienna.
One source said it was too early to say whether this latest joint effort indicated an actual narrowing of the wide differences between Iran and the six powers.
The United States, Britain, France, Germany, Russia and China began a final round of talks with Iran on Tuesday, looking to clinch a pact under which Tehran will curb its nuclear work in exchange for a lifting of economically crippling sanctions. Iran rejects Western allegations that it has been seeking to develop a nuclear bomb capability.
Officials close to the negotiations in Vienna said at mid-week the two sides remained deadlocked on key issues, are unlikely to secure a definitive accord by Monday, and might need to extend the deadline.
Separately, sources close to the talks said Omani Foreign Minister Yusuf bin Alawi was in Vienna, though Western officials said he was not playing an active mediation role in relation to the latest ideas under discussion by Kerry and Zarif. Oman was a key intermediary when Tehran and Washington launched secret talks on a possible nuclear deal more than a year ago.
British Foreign Secretary Philip Hammond said earlier on Friday in Vienna: “These are complex issues and there are still significant gaps between the parties. We’re all going away to have technical discussions with our experts and we’ll resume again over the . . . weekend.”
A senior Western diplomat said he was not optimistic about prospects for a long-term agreement by Monday’s deadline.
Russian Foreign Minister Sergei Lavrov and Kerry agreed that “additional efforts” are needed to reach a deal by the self-imposed deadline, the Foreign Ministry in Moscow said.
“The sides did not rule out the possibility of holding a ministerial meeting of the parties to the talks on Iran’s nuclear program, if the prospect for progress appears,” the ministry said in a statement.
A senior Western diplomat declined to comment on the nature of the discussions between Zarif and Kerry, but said “we are still very far away” from an agreement.
Western powers suspect Iran has aimed to covertly acquire a nuclear bomb capability from its enrichment of uranium. Iran says the program is for producing civilian energy only. The lingering dispute has raised fears of a wider Middle East war.
Zarif canceled announced plans to return to Tehran for top-level discussions with the deadline looming, Iranian media reported. The reason was not immediately known.
“The talks have not reached a stage that necessitates Zarif to go to Tehran,” an unidentified senior member of the Iranian delegation told the IRNA and ISNA news agencies.
U.S. and French officials said earlier that Kerry and French Foreign Minister Laurent Fabius would return to Paris later in the day for consultations. But they later said both ministers would stay overnight in the Austrian capital.
A source close to the talks said that Zarif had received a document from the powers that outlined the main principles of a possible agreement.
Western diplomats recently said that a U.S.-drafted proposal shown to Iran at preparatory talks in Oman earlier this month called for the Islamic republic to reduce the number of its uranium enrichment centrifuges to 4,500, well below the current 19,000 Tehran now has installed.
Iran has about 10,000 of those machines in operation. Iranian officials have refused to reduce the volume of uranium they are capable of enriching, a stand Western officials say is unacceptable as this will potentially allow Tehran to amass enough fissile material for an atomic bomb in a short period of time.
This is a major sticking point in the talks.
Another sticking point is the pace and sequencing of sanctions relief. Iran wants them terminated swiftly, not suspended and gradually scrapped, depending on the degree of Iranian compliance with the deal terms, as the West wants.
Another dispute is over the deal’s duration — the powers want it to be up to 20 years, Iran wants it to be much shorter.
“We have to get more flexibility from the Iranians,” Hammond said. “In return we are prepared to show some flexibility on our side. But time is short, we are up against a deadline here.”
An interim accord struck on Nov. 24 last year yielded steps by Iran to curb some sensitive nuclear activity, such as higher-grade enrichment, in return for some sanctions relief.
