“The situation with the S-400 arose during the previous administration (US President Barack Obama).

Presidents of (Turkey and the United States, Tayyip) Erdogan and (Donald) Trump had a good and frank dialogue and discussed all the problems.

We offered the United States to form a working group on the S-400 with the involvement of NATO, but they refused our proposal.

We expect that this administration or the new administration will be ready to solve all problems through dialogue, without threatening sanctions, ”TASS quoted Turkish Foreign Minister Mevlut Cavusoglu as saying.

Russia and Turkey in 2017 signed a contract for the supply of S-400 complexes by Moscow to Ankara.

Turkey was the first NATO country to acquire these systems from Russia.

The decision caused a backlash in the US.

US Permanent Representative to NATO Kay Bailey Hutchison said that the US expects that Turkey will reconsider its position on the acquisition of Russian S-400 complexes, realizing that it "made a mistake."
