Envoy Staffan De Mistura held "constructive" talks with Foreign Minister Walid Muallem on the plans for "freeze zones" in areas including the battered northern city of Aleppo, SANA said.
"The dialogue focused on the results of De Mistura's trips to several capitals, as well as on his proposal to the UN Security Council... regarding the establishment of a local freeze zone in Aleppo," it said.
It was De Mistura's second visit to Syria since he was appointed peace envoy in July, replacing Lakhdar Brahimi.

On October 30, De Mistura presented an "action plan" for Syria that proposed to "freeze" fighting in local areas to allow for aid deliveries and to lay the groundwork for peace talks.
De Mistura presented his plan after visiting key Damascus backer Russia.
Syria has consistently rejected a Turkish-backed plan for buffer or "safe zones" on its territory.
