Tehran staunchly avoided a direct discussion of its atomic agenda as officials from the six world powers – the US, Britain, China, Russia, France and Germany – pressed for guarantees that the Islamic state would not develop nuclear weapons.
Wrapping up two days of meetings, the EU's foreign policy chief, Catherine Ashton, said Iran will remain under UN sanctions for failure to cooperate.
Iran is currently facing a fourth round of UN sanctions, severe limitations on the sale of arms, travel bans and asset freezes for some members of the Iranian Revolutionary Guard.
These measures have not, however, proven effective in changing the Islamic Republic’s scheme and its envoy to the IAEA, Ali Asghar Soltanieh, has even gone so far as to assure that: "Resolutions, sanctions, threats, computer virus nor even a military attack will stop uranium enrichment in Iran."
When talks appeared deadlocked, US officials admitted that the most they were hoping for was an agreement to meet again, though no such plans were made.
Russian Deputy Foreign Minister Sergey Ryabkov said he isn’t completely disappointed by the results of the talks.
"I would not agree that these talks failed,” he said. "I think there was an important opportunity that was used by both parties to move dialogue forward. I would not say I am encouraged by the outcome, but to put it that I am squarely disappointed would be an overstatement. My hope is that after the Istanbul round the Iranian party will consider in a very serious manner the ideas and specific proposals that have been put forward.”
Earlier, Russian Foreign Minister Sergey Lavrov said the main focus of the six nations was establishing a concrete plan to move forward. He suggested that if Iran is able to prove its nuclear program is peaceful and pass the inspections by the International Atomic Energy Agency, the Republic could proceed with its program with international approval.
