"On July 5, [Iranian Supreme National Security Council Secretary Ali] Larijani will go to Brussels to meet with [EU foreign policy chief Javier] Solana. This issue will be discussed there, when Iran will be prepared to set out unequivocally its response to the Iran-6's proposals," Sergei Ivanov said.
Ivanov said he hoped Iran would allay the UN nuclear watchdog's concerns about its suspected nuclear weapons ambitions.
The five permanent UN Security Council members and Germany have drafted a package of incentives to persuade Iran to halt work on enriching uranium, which could be used in both electricity generation and weapons production. EU foreign policy chief Javier Solana presented the offer to Tehran during a visit to Iran June 6.
Earlier this month, President Mahmoud Ahmadinejad said Tehran would respond to the package of incentives on August 22.
Deputy Foreign Minister Sergei Kislyak said he hoped a further series of meetings between Larijani and Solana would pave the way for further talks on the nuclear problem.
"We expect further meetings between Larijani and Solana, including the first one on July 5, will show that the [negotiating] process will go on in the right direction," Kislyak said.
Kislyak said the proposals put forward by Russia, the United States, China, the United Kingdom, Germany, and France could not be disclosed at the moment under an agreement with Iran. The Islamic Republic needs time to study them, ask questions without feeling pressure, he said.
But the deputy minister added that the proposals would give Iran access to modern nuclear technology, promote its scientific development and help the republic develop the existing civilian nuclear programs.
Russia's foreign minister, Sergei Lavrov, said earlier the proposals embraced Iran's nuclear program, economic and trade cooperation with the Islamic Republic, and security guarantees.
