"After the navy success (of the Syrian military in latest months) supplementary situations have been created which favour the beginning of a political course of on a serious scale", Putin mentioned in an announcement launched by the Kremlin following the assembly within the southern Russian metropolis of Sochi.
"The Syrian president has made the decision to send his part of a delegation to form the Constitutional Committee that is to work on Syria's constitutional law".
The warships will remain on "permanent standby" to counter the "remaining terrorist threat in Syria", Russian state media quoted Putin as saying during a gathering of military and defense industry leaders at the Black Sea resort city of Sochi. Assad previously visited Russian Federation and met with Putin in November 2017 and October 2015.
Moscow has backed Syrian President Bashar al-Assad in that country's civil war since 2015, ensuring the survival of a Middle Eastern ally and guaranteeing continued access to the strategically vital Mediterranean Sea.
Assad, in turn, congratulated Putin on his re-election in March and reported "many positive changes" in Syria, including the reduction of territory controlled by insurgents and the return of "hundreds of thousands of Syrians" displaced by the conflict. Its navy help not exclusively ensured the survival of Assad's regime, it modified the course of the warfare.
A posting on the Syrian presidency's Facebook page said Assad and Putin also discussed economic cooperation and growing investments by Russian companies in Syria.
According to a Kremlin statement, Mr Assad said "stability is improving" in Syria, "opening the door to the political process we started some time ago".
