Erdogan says told Trump Turkey will not give up on Russian S-400s

President Tayyip Erdogan said on Tuesday he told U.S. President Donald Trump during talks in Washington last week that Turkey would not give up on the Russian S-400 missile defence systems it procured this year despite protests from its NATO ally.

Speaking to members of his AK Party in parliament, Erdogan also said he had told Trump that if the United States maintained its "uncompromising stance" on the F-35s, Turkey would have to seek alternatives to meet its medium-term defence needs.

Washington has said the S-400s pose a threat to its F-35 stealth fighter jets and has suspended Turkey from the jet programme, where it is a buyer and manufacturer. It has also warned of U.S. sanctions over the deal, but has yet to impose them.
