Turkey's position on its acquisition of Russian S-400 missile defence systems is unchanged and the matter is a "done deal", President Tayyip Erdogan was cited as saying on Friday, adding talks with Washington on new F-16 jets and kits were going well.
The United States imposed sanctions on NATO member Turkey's defence industry in December 2020 over the S-400s and expelled Ankara from the F-35 stealth fighter jet programme, where it was a manufacturer and buyer. Ankara says the moves are unjust.
