Iranian media outlets Press TV and the semiofficial Fars News Agency point to an anonymous Russian source who told RIA Novosti that multilateral talks in Istanbul will focus on Iran's nuclear program at the end of January.
Members of the P5+1 -- Britain, China, France, Russia and the United States plus Germany -- have called on Iran to halt production of uranium enriched to 20 percent, which Iran says it needs for medical research. Western powers, however, say it's a benchmark that would make it easier to reach the 90 percent purity needed for a nuclear weapon.
A spokesman for Iran's National Security and Foreign Policy Committee, said last week that Tehran has offered "maximum cooperation" with the P5+1, but blamed the group for lacking the "real determination" to resolve the crisis.
Talks are scheduled Wednesday between Iranian officials and the International Atomic Energy Agency.
Nuclear inspectors left Iran last month without gaining access to the Parchin military complex outside of Tehran. The IAEA there were questions about the nature of nuclear activities there.
