A summit meeting of the so-called Astana guarantor powers Turkey, Iran and Russia is taking place in Tehran today. Prior to the meeting, Iranian President Ebrahim Raisi and his Turkish counterpart Tayyip Erdogan met in the presence of numerous ministers from both countries to discuss further cooperation. Erdogan is accompanied by Defence Minister Hulusi Akar, Interior Minister Süleyman Soylu, Foreign Minister Mevlüt Çavuşoğlu, Finance Minister Nureddin Nebati, Energy Minister Fatih Dönmez, his spokesman Ibrahim Kalin, and the Ministers of Youth and Sports, Trade and Industry and Technology.

Another meeting took place between Erdogan, Raisi and Ayatollah Ali Khamenei. Khamenei's office said after the talks that economic relations and cooperation between Turkey and Iran should be strengthened. The statement pointed out the importance of Syria's territorial integrity, saying any possible attack on the north of the country would be to the detriment of Turkey, Syria and the entire region, and that the Syria issue must be solved through dialogue between Iran, Turkey, Syria and Russia.

The Astana-format summit will also be attended by Russian President Vladimir Putin. The "Astana process" was launched in Kazakhstan in 2017 and labelled with the name of the Kazakh capital at the time, while today it is called Nur-Sultan. One of the main topics of discussion will be Erdogan's announced invasion of northern Syria.
