Russian President Vladimir Putin and his Turkish counterpart Recep Tayyip Erdogan stressed on Wednesday the importance of the agreements that were reached a day earlier at the Sochi-hosted Syria peace congress.
A Kremlin statement said Putin and Erdogan explained that agreements were aimed at finding a solution based on a UN Security Council's resolution.
"The heads of state expressed satisfaction with the results of the Congress of Syrian National Dialogue held in Sochi on January 30," added the statement.
The presidents also spoke of the "further coordination of Russia and Turkey's efforts to ensure the stable functioning of de-escalation zones" in Syria established by Turkey, Iran and Russia last year.
On Tuesday, Russia hosted a Syria peace congress in an effort to find a peace settlement after seven years of war, but the conference closed without a significant breakthrough after a string of boycotts and last-minute cancellations.
Nevertheless, UN Syria envoy Staffan de Mistura said delegates had agreed to the formation of a committee to discuss the war-torn country's post-war constitution.
Around 1,400 delegates attended the meeting.
Later on Wednesday, a source from Erdogan’s palace revealed that he had agreed with Putin to step up efforts to form observation posts in the northwestern Syrian province of Idlib.
Erdogan also shared information with Putin regarding Turkey’s incursion into Syria’s Afrin region, the source added.
