According to the Kremlin, Putin and Erdogan noted the importance of the full implementation of the existing Russian-Turkish agreements, including the Sochi memorandum signed on Sep 17, 2018.

In the memorandum, Turkey and Russia agreed to turn parts of Idlib, the last major rebel stronghold in Syria, into a de-escalation zone, where acts of aggression are prohibited.

But the document was never fully implemented as rebels were not removed from the de-escalation zone and the armed conflicts did not die down.
