"Considerably due to your position, Mr. President, the drastic improvement of the situation in Syria has been achieved: terrorists suffered significant losses and the significant progress in the peace settlement was reached," Putin told Erdogan.
The Russian president highly appreciated the Turkish position as well as positions of all partners taking part in the negotiating process.
Putin also praised the recent developments in the bilateral Russian-Turkish relations.
"Much work has been recently done both for the comprehensive development of the bilateral relations and for solving a number of issues interesting for us," the Russian leader said.
