The technical meeting involves experts from Turkey, Russia and Iran -- who agreed last month to create a cease-fire monitoring group -- as well as representative of the UN and Jordan.
The parties are due to release a statement following the meeting, the Kazinform news agency reported.
The January meeting in Astana saw Russia, Turkey and Iran agree to a trilateral mechanism for observing and ensuring compliance with a cease-fire that came into effect on Dec. 30. Representatives of the Syrian government and the armed opposition groups also attended the meeting.
Talks are due to take place between the government and opposition in Geneva on Feb. 20.
