Turkey says it will take reciprocal steps if the United States imposes sanctions over its purchase of Russian S-400 defense missile system.

The Turkish Foreign Minister Mevlut Cavusoglu in an interview in Ankara said that no matter what the results will be, Turkey will not take a step back.

Ankara and Washington have sparred publicly for months over Turkey’s purchase of the S-400 missile systems, expected to be delivered as early as next month.
