Russian President Vladimir Putin said any proposed safe zones in Syria should become no-fly areas if fighting on the ground stops entirely.
"If there is a de-escalation zone, then planes will not fly there on condition that no military activity emanates from these zones," Putin said at a press conference with Turkish leader Recep Tayyip Erdogan.
Speaking after holding talks with Turkish President Tayyip Erdogan in the Black Sea Russian resort of Sochi, Putin said relations were finally getting back to normal and that trade had stopped falling.
"Some time ago our bilateral ties, as it well known, were tested. Now we can say with certainty remark that the recovery process in Russo-Turkish ties is complete," Putin told a news conference. "We are getting back to a normal cooperative partnership."
Putin said Russia would launch a joint investment fund with Turkey with funds of up to $1 billion and said Moscow stood ready to help Turkey improve security measures at its tourist resorts.
