Thus, she commented on reports of the offer of the American senator to buy S-400 air defense systems from Turkey.

According to Vorobyova, for the export of military products, the buyer of Russian equipment must provide Russia with an end-user certificate.

“Therefore, its transfer or re-export to third countries without the official permission of the Russian side is impossible,” she stressed.

Earlier, the Defense News newspaper reported that Senator John Thune proposed an amendment to the Senate that would allow the US side to buy the Russian S-400 from Turkey at the expense of the ground forces budget.

In mid-May, the United States announced that the acquisition of Ankara S-400 remains the main problem in relations between the two countries.
