VIENNA, July 05, /ITAR-TASS/. Representatives from Russia’s nuclear power concern Rosatom will join the negotiations between Iran and the sextet of international mediators next week, Russia’s Deputy Foreign Minister Sergey Ryabkov told the media on Friday.

“Our delegation, all of its experts and specialists are staying here for the whole period,” he said. “Representatives from the state-run corporation Rosatom are joining us next week.

“We believe that Russia’s contribution is tangible and allows for using many of our ideas and accelerate progress towards agreements,” Ryabkov said.

“Heavy effort is still to be exerted, though.”

Ryabkov has left Vienna for several days for taking part in preparations for the BRICS summit in Brazil, because he is Russia’s sherpa in this international format.

“I am a BRICS sherpa, I have not been relieved of this duty of mine yet. I am obliged to go to Brazil to agree the summit’s final document,” he explained.

Also he said that the start of the final round of talks between Iran and the sextet of international mediators is not disappointing, but the consultations are proceeding slowly.

“The beginning has proved not a disappointing one, but it has turned out slower than it was originally anticipated,” he said. “It is important that the work on the text is going on, although the main problems are still there,” he said.
