"Russia is the main winner, because without a single bullet, it filled the void created by the withdrawal of (troops) from the United States and assumed the leading position in advancing the democratic process," Yakis told Sputnik.
According to the former chancellor, the Russian-Turkish memorandum will prevent a direct military confrontation between Turkey and Syria.
"Syria has no reason to enter into a military confrontation with Turkey as it has other priorities," he said.
Turkey began the Peace Source operation in northern Syria on October 9 with the argument of removing Kurdish militias from its border and delimiting a "safe zone" to accommodate the thousands of Syrian refugees remaining in its territory.
A week later, Ankara agreed with Washington to suspend the operation on condition that Kurdish forces were withdrawn from the security zone.
On October 22, Russian and Turkish leaders Vladimir Putin and Recep Tayyip Erdogan decided to prolong the truce and deploy Russian military police and Syrian soldiers in northeastern Syria, but outside the area where Turkey operates.
It was also established that the forces of Russia and Syria will facilitate the transfer of Kurdish factions at a distance of 30 kilometers within 150 hours from noon on October 23, at which time the Russian-Turkish patrol will begin 10 kilometers from the border in both east and west direction of the area of the Turkish military operation, although excluding the city of Qamishli.
According to Turkish Foreign Minister Mevlut Cavusoglu, the Turkish operation in Syria is suspended but not completed and can be resumed if necessary.
