Russia hopes to seal a deal to supply Turkey with more S-400 missile systems in the first half of next year, the head of Russian state arms exporter Rosoboronexport was cited on Tuesday as saying.
Such a move could further sour ties between Turkey and the United States, which has suspended Ankara from the F-35 stealth fighter jet programme, in which it was a producer and buyer, to punish it for buying S-400 batteries earlier this year.
