Idlib Operation
"The issue of the special zone in Idlib is being discussed" — according to the Turkish envoy to Russia, Huseyin Dirioz, Ankara has "recently set an observation post" in the embattled city and will "continue the work aimed to ensure the ceasefire regime and political settlement."
Ankara kicked off the military operation in northwestern Syria, aimed at ensuring the creation of the de-escalation zone and ending violence in the province of Idlib, on October 12.
S-400 Deliveries to Turkey & Turkish Stream
The initial deal on the delivery of anti-aircraft defence systems was sighed in September. Moscow has since confirmed that an up-front payment for the S-400s has been made and the delivery was scheduled for 2019.
Huseyin Dirioz has also touched upon the Turkish Stream gas pipeline issue, saying that Ankara is satisfied with the project's implementation.
Prospects of Russian-Turkish Trade
Acording to Dirioz, the turnover between Moscow and Ankara has increased by some staggering 60 percent after mutual economic restrictions were removed, though it hasn't yet returned to the previous level of $40 billion per year.
Russian-Turkish trade has been facing significant difficulties since 2016, when Russia introduced a food embargo against Turkey in response to the 2015 downing of a Russian aircraft over Syria. The bilateral ties normalized following an apology from Turkey's president Erdogan and the food embargo was partially lifted.
