Representatives of the Syrian government and opposition groups are meeting once again in the capital of Kazakhstan.
Sergey Lavrov, Russia's foreign minister, told Russian state media that delegations from Russia, Iran, and Turkey, with the attendance of experts from the US, Jordan and the UN would discuss "the establishment of a de-escalation zone in Idlib".
"Astana is exactly the additional tool which helped groups to reach some technical agreement on the ground which basically lay the ground to further negotiations," Alexey Khlebnikov, of the Russian International Affairs Council, told Al Jazeera.
Speaking from Astana, Al Jazeera's Charles Stratford said the focus would primarily be on the de-escalation zones.
However, he said, "the complexities of the situation on the ground in Syria and the lack of agreement over which countries could potentially offer troops to monitor these zones show just how difficult reaching consensus here could be".
