When asked about the likelihood of Putin visiting Iran and participating in an Astana format summit, the Russian spokesman responded, "He will certainly [travel there] over time, but exact dates are yet to be determined."
On Thursday, Iranian Foreign Minister Hossein Amirabdollahian expressed hope that the Iran-Russia-Turkey summit will eventually convene in Tehran.
Plans to hold such a meeting were announced even before the novel coronavirus pandemic, but the event had to be postponed many times since.
