The debate over the Adana agreement could be seen as the starting point for Turkey`s talks with Moscow on the safe zone. Erdoğan`s emphasis on the PKK`s capitulation to Turkey has also been remarkable. Let us be clear, this agreement was not limited to the capitulation of PKK leader Abdullah Öcalan to Turkey. He called on Syria to treat the PKK as a terrorist organization, ban its activities and bring its members to justice. Apparently, earlier this week, Erdoğan invoked the Adana agreement in reference to the YPG, the Syrian branch of the PKK. Russia – a staundy ally of al-Assad – proposed on Tuesday, during a meeting between Presidents Vladimir Putin and Recep Tayyip Erdogan, that any Syro-Turkish rapprochement be based on the Adana agreement. Russia proposes that the agreement, if fully implemented, could resolve one of the most difficult disagreements in the Syrian conflict – the status of the YPG. 20, 1998, was the most critical topic on the agenda during the meeting between Turkish President Recep Tayyip Erdogan and Russian President Vladimir Putin in January. .
