"Diplomacy and chess strategy are the key factors which define the developments on the battlefield in Syria," the political scientist told Sputnik.
"Russia is advocating the territorial integrity of Syria and Iraq. This is exactly what President Putin had in mind when speaking about the need to adhere to the norms of the international law while settling the crisis in this region," he added.
Mesut Hakkı Casın further noted that during the G20 summit in Hangzhou President Recep Tayyip Erdogan also said that Turkey’s ‘Shield of the Euphrates’ operation is not aimed at violating the territorial integrity of Syria.
Otherwise it could lead to a new influx of refugees who have already flooded Turkey, and Europe will then get 1,5 million more migrants from Aleppo.
Besides Turkey, it will come as a crushing burden to a number of European countries, and first and foremost to Germany, the expert said.
Meanwhile during his press conference at the G20 Summit, Barack Obama said that while the US and Russia had some "productive conversations" on the ways of settlement of the Syrian conflict, there are still "gaps of trust" between the two countries.
"All the above means that unlike the US, Turkey and Russia do understand each other on Syria," Casın told Sputnik.
"I think that Presidents Putin and Erdogan will be able to make an agreement on Aleppo in the nearest future, which will lead to the announcement of ceasefire for Kurban Bayrami celebrations and to the opening of humanitarian corridors," he added.
"Russia, undoubtedly, is playing a leading role among the five countries who define the situation in Syria, along with the US, Saudi Arabia, Iran and Turkey," said the political scientist.
If any of the above countries is taken off the table, there will be no agreement reached on the settlement of the conflict.
However the current situation, he said, is complicated with the mutual distrust of the players.
All the parties to the conflict should be interested in and have a clear intention for a ceasefire in the region.
However the US, using the Syrian Kurds, wants to set up such a Syria, which will be in their own geopolitical interests.
Meanwhile, the expert reiterated, Moscow, Damascus and Tehran insist on adherence to the principle of Syria's territorial integrity.
Thus, he said, what should be done as soon as possible is to announce the cessation of hostilities in accordance with the norms of the international law. And all the large players in the region should realize this.
