Tehran: Iranian Foreign Minister Mohammad Javad Zarif and top US diplomat John Kerry will meet in Geneva this week for talks on Tehran's nuclear programme, an Iranian official said today.
Iran and world powers are trying to strike a deal that would prevent Tehran from developing a nuclear bomb, a goal it denies having, in return for an easing of punishing economic sanctions.
Zarif and Kerry will hold two days of discussions from Sunday after their diplomats begin bilateral talks on Friday, Iran's deputy foreign minister Abbas Araghchi said.
"After four days of bilateral discussions between the Iranian and US nuclear delegations, they could continue with the participation of all members of the P5+1," Araghchi was quoted as saying by the official IRNA news agency.
He was referring to Britain, China, France, Germany, Russia and the United States, which are seeking to thrash out a complex deal with Iran.
"These bilateral consultations will take place in the context of the P5+1 nuclear negotiations with Iran," the State Department said, adding that the European Union's deputy foreign policy chief Helga Schmid would also join the talks.
Tehran denies ever seeking atomic weapons but Western powers are unconvinced its activities have been solely aimed at peaceful energy production.
Under an interim deal struck in November 2013, Iran's stock of fissile material has been diluted from 20 percent enriched uranium to five percent in exchange for limited sanctions relief.
But scepticism is mounting about whether a permanent agreement is possible, after two deadlines for a comprehensive deal were missed.
Negotiators are now working toward reaching a political framework for a deal by March 31, with the final technical details to be laid out in a comprehensive accord by June 30.
Zarif has met multiple times with Kerry, most recently in Munich earlier this month on the sidelines of a global security conference, when both spoke out against any further deadline extensions.
Iran's supreme leader Ayatollah Ali Khamenei has also voiced opposition to the two-stage accord process.
"Any agreement must come in one step, and include both a general framework and details" of a deal, he said earlier in February.
China's Foreign Minister Wang Yi, speaking in Tehran last week, said the negotiations had seen "positive progress" but had become "more difficult and complicated" as they near conclusion.
