"Russia is our friend. It must support us in the political arena. We are awaiting stronger solidarity from friends," Muslim said in an interview.
He added that Moscow was in the heart of the solution of the Syrian issue and could use its authority during the next round of Geneva talks on Syria’s reconciliation.
"Russia has an effective force in this matter, it can do something for the Syrian settlement," Muslim said.
While the Kurds are the largest ethnic minority in Syria, none of their representatives have been invited to the intra-Syrian negotiations, the latest round of which took place in Geneva on April 13-27.
Russia has been calling on the United Nations to invite Syrian Kurds to the proximity talks on settlement of the five-year civil war in Syria.
