ANKARA, Nov. 19 (Xinhua) -- The foreign ministers of Turkey, Russia and Iran discussed Syria issues Sunday in Turkey's Antalya, ahead of an upcoming trilateral summit in the Russian city of Sochi on Wednesday.
"The Astana talks achieved positive results. We have come a long way with Russia, especially in terms of the establishment of peace on the field and forming de-escalation zones. Situation on the field is much better compared to last year," Turkish Foreign Minister Mevlut Cavusoglu said Sunday after meeting Russian Sergey Lavrov and Iranian Javad Zarif.
Cavusoglu said the purpose of the Sochi summit was to evaluate what the three guarantor countries have succeeded about Syria so far, and the steps that should be taken in the future.
"We now have to concentrate on a political process, while continuing to target terrorist organizations like DAESH (Islamic State)," Cavusoglu said.
As for Kurdish issues, the minister stressed that the participation of PKK/PYD organization in Sochi summit would be "unacceptable" for Turkey.
The Presidents of Turkey, Russia and Iran will hold a meeting to discuss Syria issue and recent regional situation in Russia's Black Sea resort city of Sochi on Nov. 22.
Turkey, Russia and Iran are guarantor countries that brokered a ceasefire in Syria in December 2016, which led to the Astana talks, being held in parallel with UN-backed discussions in Geneva to find a political solution to the six-year conflict.
