Putin also welcomed the defeat of rebel forces in Syria's second city and said cooperation between Tehran and Moscow "will continue".
They said peace talks would take place in Kazakhstan, without providing further details.
Iran and Russia have been the key backers of Syrian President Bashar al-Assad and label all rebel forces in the country as "terrorists".
"The result of this cooperation is a major victory in the fight against international terrorism," added Putin.
Syrian troops this week retook control of eastern Aleppo, which has been held by disparate rebel groups since mid-2012, after a devastating month-long offensive that has caused tens of thousands of refugees to flee their homes.
Russia's entry into the conflict in September 2015 -- primarily through air strikes -- helped turn the tide for Assad, while Iran has provided military advisors and frontline "volunteer" fighters.
