Moscow will not assess critiques from NATO officials regarding the sale of S-400 air defense systems to Turkey, a Russian foreign ministry official said Tuesday.
"It only concerns us and Turkey," head of the NATO division in the Russian foreign ministry's Department of European Cooperation, Kirill Logvinov said, when asked to comment on the alliance member states' concerns regarding the S-400 deal with Ankara.
"If our Turkish colleagues are interested in these types of weapons, if they are ready for negotiations, they are interested in supplying, we are here open [for talks] to any country, regardless of membership in this or that military and political bloc," Logvinov added.
Turkey agreed to buy S-400 — Russia's most advanced long-range anti-aircraft missile system — in a more than $2 billion deal in September.
The first system is expected to be delivered in 2019.
