Turkish Foreign Minister Mevlut Cavusoglu rejected the claims that Turkey would delay the procurement of the Russian-made S-400 air defense systems. He said Ankara and Washington are continuing to exchange views to establish a committee to elaborate the impact of its purchase of the Russian missile defenses systems on the U.S. F-35 fighter jets. Earlier this week, Washington had asked Ankara to delay the delivery of the S-400 Russian missile defense system, which is slated for July, after Turkey demanded to form a working group. However, according to a Reuters report, citing a senior Turkish official, Turkey expressed unwillingness to delay taking the delivery. U.S. officials describe Turkey’s Russian defense system purchasing “deeply problematic,” calling the country risk its partnership in the joint F-35 program.
