According to diplomatic sources who spoke on condition of anonymity, the parties will finalize the technical details in Turkey. The date of the meeting in Ankara was not specified.
Russia's Special Envoy on Syria Alexander Lavrentiev told reporters after the meeting in the Kazakh capital Astana: "This common group will ensure and monitor the truce in particular. It will also work on different aspects of the political process."
Astana hosted another round of intra-Syrian peace talks with representatives of Russia, Turkey and Iran, who agreed last month to create a cease-fire monitoring group.
The January meeting in Astana saw the three countries agree to a trilateral mechanism for observing and ensuring compliance with a cease-fire which came into effect on Dec. 30.
