Iran's top nuclear negotiator says a Russian proposal aimed at resolving Tehran's nuclear standoff with the West is useful, but needs further discussion.
Ali Larijani made the remark Thursday at a news conference in Beijing, where he has been meeting with Chinese officials.
China urged all parties to resolve the nuclear issue through diplomatic efforts.
The Russian proposal calls for allowing Tehran to enrich uranium on Russian soil for use in Iran's reactors.
Western governments accuse Tehran of secretly trying to build nuclear weapons, but Iran denies the charge.
Monday, the foreign ministers of Britain, France, Germany, Russia, China and the United States will meet in London to discuss a joint strategy for dealing with the nuclear standoff.
The International Atomic Energy Agency meets on February 2 in Vienna, when the West is expected to push for referring Iran to the U.N. Security Council for possible sanctions.
