Kremlin spokesman Dmitry Peskov stated that Putin will travel to Tehran next Tuesday to attend a trilateral meeting with the leaders of Iran and Turkey, the so-called Astana format of meetings for Syria-related talks.
Peskov told reporters that during the visit, Putin will also have a separate meeting with Turkish President Recep Tayyip Erdogan.
Putin met with his Iranian opposite number Ebrahim Raisi during his trip to Ashgabat in mid-July.
In January, Raisi visited Moscow at the head of a high-ranking delegation at the invitation of his Russian counterpart.
In a meeting with Putin, the Iranian president noted there was no hindrance in the way of further expanding relations between the Islamic Republic and the Russian Federation.
