Kremlin: U.S.-Turkey plans to create S-400 working group - none of Russia’s business

Russian President’s press secretary Dmitry Peskov refused to comment on the United States and Turkey’s intention to establish a working group to settle the differences arising from Russia supplying S-400 missile system to Ankara.

The Kremlin spokesman said that Turkey does not have to notify Russia about the creation of a working group. "This is none of our business," he noted.

"Our business and the business of our Turkish partners is to complete the S-400 deal, which is currently underway," TASS cited Peskov as saying.

Turkey can discuss its plans "with any third parties," Peskov concluded.
