This is not the first visit by the Turkish President to Russia this year. In April, Mr Erdogan and I held a productive meeting of the High-Level Russian-Turkish Cooperation Council in Moscow; we also met at other sites. In mid-September, I will go to Ankara for a trilateral summit of Russia, Turkey and Iran, guarantors of the Astana process for Syria. Mr Erdogan is also invited to take part in the Russian Energy Week forum in Moscow in October.
