Russia believed Iran has been ready to coordinate its actions over its nuclear program, Foreign Minister Sergei Lavrov said Wednesday.

Russia has a clear impression that Iran "is ready to coordinate the particular actions" to seek agreements "within the framework of the approach based on phasing and reciprocity," Lavrov told reporters.

Key talks to resolve the nuclear dispute between Iran and the world's six major powers in addition to the European Union have started in the Iraqi capital Baghdad on Wednesday.

The talks were aimed at pushing Iran to allow experts from the International Atomic Energy Agency (IAEA) access to sites, people and documents the IAEA hoped to inspect to address concerns that the country might have been working on nuclear weapons.

Lavrov said Moscow expected the Baghdad meeting would elaborate "the algorithm of the further joint work" and practical steps to resolving the Iranian nuclear problem.

"This will be the process we would like to see the particular results at every step: Iran makes a step toward the requirements of the international community, the international community makes the steps which ease sanction pressure on Iran," the diplomat said.

Lavrov said this process must continue until "we reach the point where it is clear for everybody the Iranian nuclear program has no military dimension."

Russia opposed the U.S. unilateral sanctions against Iran and saw them as "absolutely unacceptable", Lavrov said.

Those sanctions have threatened the joint work of the Group of Six and unity of its members' actions, as they have been aimed at choking Iran's economy and not nuclear nonproliferation, said the diplomat.

Lavrov said Russia hoped U.S. President Barack Obama would not support the new sanctions against Teheran passed by the Congress.

"On the eve of the Baghdad round (of the talks) the actions were undertaken which did not facilitate the atmosphere favorable for moving forward," he noted.

The EU, the United States and some other countries have imposed oil embargo as part of their sanctions to pressure Tehran into resuming talks on its nuclear program.

They have also imposed tough banking sanctions aiming at limiting Iran's ability to sell oil, which accounts for 80 percent of its foreign revenues.
