He added that the Russian side was very grateful to Iranians for this kind of initiative and the offer was accepted.
"We will be preparing the meeting," Ushakov said.
The upcoming meeting will be the first for the leaders of the two countries and the second meeting at the highest level since early July, when ex-president of Iran Mahmoud Ahmadinejad visited Moscow.
Ushakov reminded that earlier the speaker of the Russian State Duma (Parliament) Sergei Naryshkin visited Iran to represent Russia during Rouhani`s inauguration.
Earlier, media outlets were reporting that Putin can visit Iran in August, but the Russian government stated that there are no such plans on the agenda.
