The delegation led by Deputy Russian Foreign Minister Sergey Vershinin will hold talks with their Turkish counterparts headed by Turkey’s Deputy Foreign Minister Sedat Onal, the Turkish Foreign Ministry said.However, citing two Turkish sources, Reuters reported on Dec. 2 that Damascus was resisting the Russian efforts to broker a summit between the two leaders.Asked about the Russian delegation’s visit on Wednesday, Turkish Foreign Minister Mevlut Cavusoglu stopped short of repeating Ankara’s threats, but aired a rare complaint over the Russian stalling of the constitutional talks between the warring Syrian actors.We've been stressing how important this is for the sake of permanent stability.”He added that the war in Ukraine, Libya and bilateral issues would also be discussed during the talks.Since then, Russia has refused to send a delegation to the talks between the rebel groups and the Syrian government held under the auspices of the UN in Geneva, Switzerland."
