"In general, we have accomplished a lot in all aspects, and even in areas where the differences still remain we continue to come closer in our positions," Ryabkov, who is Russia's envoy at the talks said.
"I think that the talks are looking promising," the diplomat said, following a fresh round of Iran nuclear talks in Geneva.
"The place is still being coordinated with the Iranian delegation," Ryabkov said.
Earlier in the day, the deputy Foreign Minister said that an agreement on Iran's nuclear program would boost global security and expressed hope that there would be no rollback in the talks.
The P5+1 group of six world powers, comprising Russia, the United States, the United Kingdom, France, China and Germany joined diplomatic efforts back in 2006 in an attempt to reach a deal with the Tehran authorities, assuring the peaceful nature of the Iranian nuclear program.
The round of talks between Iran and the P5+1 group held in November in Vienna shortly before the previously announced deadline did not produce a comprehensive deal on Iran's nuclear program and the sides agreed to continue the discussions until July 2015.
