VIENNA: US Secretary of State John Kerry and fellow foreign ministers are adding their diplomatic muscle to nuclear talks with Iran, with a target date only a week away for a pact meant to curb programs Tehran could turn to making atomic arms.

Deep differences separate the two sides and six world powers and Iran appear set to extend their talks past July 20. That would give more time to negotiate a deal that would limit the scope of such programs in exchange for a full lifting of nuclear-related sanctions imposed on Tehran.

“Obviously we have some very significant gaps still, so we need to see if we can make some progress,” Kerry told reporters before a meeting with European Union foreign policy chief Catherine Ashton, who is convening the talks.

“It is vital to make certain that Iran is not going to develop nuclear weapons, that their program is peaceful. That’s what we are here trying to achieve.”

Kerry arrived Sunday. Britain, France and Germany also sent their foreign ministers to Austria’s capital for talks over the next few days, as has Iran. But the top diplomats from China and Russia are sending lower-ranking officials instead. That may reflect their view that an extension is unavoidable.

Still, the most important disputes over how deeply Iran must cut its nuclear program are between
Washington and Tehran, so Kerry’s presence is crucial. He will be able to talk directly to Iranian Foreign Minister Mohammad Javad Zarif, who is at the Vienna negotiations.

Iranian Deputy Foreign Minister Abbas Araghchi spoke Saturday of “huge and deep” differences. But he
told Iranian TV that “if no breakthrough is achieved, it doesn’t mean that (the) talks have failed.”

Kerry arrived in Vienna after diplomatic success in Afghanistan, where he persuaded rival presidential candidates to agree to a full audit of their recent runoff election. They also agreed to a power-sharing arrangement.

In Austria’s capital, the top American diplomat has perhaps a harder task.

Discussions center on imposing long-term restrictions on Iran’s uranium enrichment and against plutonium production — materials usable in nuclear warheads. In exchange, the US and other powers would scrap a series of trade and oil sanctions against Tehran.

In Iran, hardliners oppose almost any concession by moderate President Hassan Rouhani’s government.

And in the US, Republicans and Democrats have threatened to scuttle any emerging agreement because it would allow Iran to maintain some enrichment capacity.

Outside the negotiation, regional rivals of Iran including Israel and Saudi Arabia are extremely skeptical of any arrangement that would, in their view, allow the Islamic republic to escape international pressure while moving closer to the nuclear club.

Iran says its program is solely for peaceful energy production and medical research purposes, though much of the world fears it’s a covert effort toward nuclear weapons capability.

An interim deal in January effectively froze Iran’s program, with world powers providing sanctions relief to Tehran of about $7 billion. They two sides also agreed to a six-month extension past July 20 for negotiations to reach a comprehensive deal if necessary.

It’s too early, says Britain

VIENNA: It is too early to consider extending the talks between Iran and six world powers on Tehran’s nuclear program beyond next week’s deadline, though major divisions remain between the two sides, British Foreign Secretary William Hague said on Sunday.

“There are very significant gaps, that is very clear,” he told reporters about the positions of Iran and the six powers — the United States, Britain, France, Germany, Russia and China. “It is unlikely there will be a quick breakthrough today but we … shall see what scope there is for making a progress before July 20,” Hague added.
