Turkish President Recep Tayyip Erdogan said he informed US President Joe Biden that Ankara won’t change its position on the Russian-made S-400s, he told reporters on Thursday.
"I told [Biden], don't expect us, as Turkey, to take a different step on either the F-35 or S-400 issue because we did our part on the F-35s and gave the necessary money,” Erdogan said while in the Azerbaijani capital Baku.
