Turkey and Russia's developing cooperation on Syria continues to create new opportunities in the solution of the crisis. The agreement reached between Turkey and Russia had stopped the humanitarian crisis in Aleppo from deepening and civilian deaths. Iran starting to contribute to this cooperation resulted in the Moscow Declaration. A Syria summit is taking place in Astana with Turkey, Iran and Russia's participation. This is the first time since the beginning of the crisis that the region's countries, which are taking initiative upon the failure of Geneva and Western attempts, have come so close to solving it.
