"I have not heard of any official invitation to hold a ministerial meeting in any format on Iran," Lavrov said.
U.S. Ambassador to the United Nations John Bolton said Thursday that the five permanent Security Council members should hold talks before the UN adopts a final decision on Iran.
Lavrov said he was aware of a document available on the Internet that allegedly outlined a strategy on Iran drafted by the United States, Germany, France and Britain, and kept secret from Russia.
"It would be strange if this information were confirmed," Lavrov said. "We have been trying to convince our partners to adopt a joint action plan on Iran for the last several months."
Lavrov said the issue could be discussed thoroughly at the level of foreign ministers if Russia received an official invitation.
The International Atomic Energy Agency, the UN's nuclear watchdog, March 8 referred its file on Iran's nuclear program to the UN Security Council, which has the power to impose sanctions on Iran should the country be found in breach of its international commitments.
Russia has proposed alternative solutions to the impasse, including a joint venture to enrich uranium for Iran on Russian soil.
