ANKARA (Reuters) - Turkey’s relations with Russia are not an alternative to its ties with NATO and the European Union, Turkish Foreign Minister Mevlut Cavusoglu told a joint news conference with his Russian counterpart Sergei Lavrov in Russia on Tuesday. His comments came after fellow NATO member Washington sanctioned Turkey over its purchase of Russian S-400 missile defences, and the EU prepared punitive steps over Turkey’s dispute with members Greece and Cyprus over Mediterranean offshore rights.
