Turkey will not succumb to the US on the purchase of Russian S-400s, said Turkish FM Mevlut Cavusoglu.

Turkey may buy US Patriot if conditions are right, but a deal will be impossible if US forces Turkey not to purchase the S-400s form Russia, Reuters reported. 

The US delegation will visit Turkey in the coming weeks to convey concerns about the S-400 deal.

On December 18, 2018, the US administration decided to sell Patriot air defense systems to Ankara for a total of $ 3.5 billion.
