If Turkey decided to buy the S-400 air defence systems from Russia, it would be a cause for concern in the United States, Chairman of the US Joint Chiefs of Staff Joseph Dunford said on Sunday, Sputnik reported.
"There was a media report that was incorrect, they have not bought the S-400 air defence system from Russia. That would be a concern, were they to do that, but they have not done that," Dunford said at the Aspen Security Forum in Colorado.
As of today, Russia only concluded a deal on supplying the S-400 system with China, and the talks are underway with Turkey and India. On Tuesday, Turkish Defense Minister Fikri Işık said that the negotiations regarding Russia's delivery of S-400 air defence systems to Turkey have reached the final stage.
