Iran and the six world powers (the US, Russia, China, France, Britain and Germany) can reach a comprehensive agreement before the July deadline, Russian Deputy Foreign Minister Sergei Ryabkov underlined on Friday, IRNA reported.
'The final nuclear agreement with Iran can be signed within three or four months,' Ryabkov was quoted as saying by Russia Today website.
'We share the opinion that this timeframe is realistic," Ryabkov added all the same, due to the probable emergence of any unpredictable inconsistencies in the course of the talks.
He noted that Moscow will push for intense talks between the Iran and the Sextet.
"We believe, new extensions will simply be both unnecessary and impossible," the senior Russian negotiator stressed.
The 10th and last round of negotiations between Iran and the six world powers was held in Vienna from November 18 to 24.
In July, Tehran and the six countries agreed to extend negotiations until November 24 after they failed to reach an agreement on a number of key issues.
