"The two top diplomats discussed prospects for cooperation in regional affairs with a focus on the Syrian settlement in the context of efforts towards strengthening and expanding the ceasefire in Syria following the memorandum on de-escalation zones, including near the border with Jordan, signed in Astana on May 4 and supported by the Syrian government," the ministry said.
