"Both sides will try to sign agreements in different fields, including in the oil and natural gas sector," he said Tuesday.
Western governments had expressed concern over the possibility that Iran was working on an oil-for-goods swap deal with Russia. Iranian Oil Minister Bijan Zanganeh said the government had endorsed such a deal, but nothing was formalized.
"We do not have any oil barter trade deal between Iran and Russia," he said in a statement.
Both sides already cooperate in a variety of fields, with Russia supplying fuel for Iran's nuclear reactor at Bushehr. The president's chief of staff said Tehran and Moscow have met to strengthen their economies ties.
"The details of Iran-Russia contracts will be announced in the future," he said.
Iran has been eager to make deals in an energy sector handicapped by Western economic sanctions pressure.
