Larijani made the remarks in a meeting with Belarus’ President Alexander Lukashenko on Friday, IRNA reported.
The Iranian top parliamentarian expressed Tehran’s readiness for boosting exports and imports between the two countries, describing it as an important move.
Belarusian president welcomed the idea and offered readiness for developing trade, industrial and agricultural relations.
Heading a delegation that comprises several parliamentarians, Larijani arrived in Belarus on Friday on the last leg of a four-day tour that also took him to Russia.
On Thursday, the Iranian delegation attended a meeting with senior Russian lawmakers in the southwestern Russian city of Volgograd.
“Iran and Russia have had a great share in fighting terrorism, and the terrorists are today drawing their last breaths in Syria,” Larijani said during the meeting.
The US behavior toward Russia and Iran has witnessed some changes, he said, noting that Tehran and Moscow should to the same degree hold closer consultations with each other to better respond to Washington's actions, Press TV reported.
Vyacheslav Volodin, the chairman of the State Duma (the lower house of the Russian Parliament), said, “The Americans want to decide exclusively and unilaterally, and form a unipolar world.”
He said relations between Iran and Russia were already expanding “dynamically,” adding that the volume of bilateral trade between the two countries had increased by 30 percent year-on-year. However, the top parliamentarian emphasized that Tehran and Moscow still needed to do more to boost their bonds.
Iran's top parliamentarian, meanwhile, said Iran and Russia needed to further expand their cooperation specifically in the area of railroad transportation.
