Many EU countries are not in the Eurozone. Turkey and EU have a longstanding relationships with Turkey taking part in many of the EU institutions, like the customs union for example. In many ways Turkey acts as an industrial base for EU, many many EU companies have facilities in Turkey that serve EU. Turkey is also in the Council of Europe, is in the jurisdiction of European Court of Human Rights(pays a lots of fines, unfortunately), European Border and Coast Guard Agency. Turkey implemented GDPR compatible privacy laws, it has its infrastructure compatible and integrated with EU etc. Roads, electricity, gas, trains - everything is by the EU standards and integrated within the EU. Environment protection and worker rights are also not that far off. Turkey and EU fell apart only on political level and things like the upholding of the rule of law. In fact, Turkey is one secular government away from being full EU member. For comparison with US, Turkey exports about $140B to EU and only about $14B to US. No matter the politics, it's EU what matters to Turkey and US is a distant 3rd with being only about %8 of the Turkish exports(Europe is %58).
