The declaration was issued in a brief statement tonight in Moscow following talks between Ivanov and Iranian Supreme National Security Council Secretary Ali Larijani.
The statement followed discussions between Iranian Deputy Foreign Minister Mehdi Safari and the head of Russia's Atomic Energy Agency (Rosatom), Sergei Kiriyenko. The talks focused on Russia's participation in building Iran's Bushehr nuclear power plant.
The United States and the European Union are concerned about Iran's recent resumption of its nuclear program. They want the matter to be referred to the UN Security Council for possible sanctions.
Iran has denied charges that it is seeking to develop nuclear weapons, saying its program is for peaceful purposes.
