The paper deals with political and economic issues of the Turkish foreign investments in Croatia. After Croatia's accession to the European Union, Turkish investments in Croatia increased significantly, so the question was whether these investments were encouraged by Croatia's membership in the EU. Theoretically EU membership brings security to investors because, country members had to adapt institutional and legal frame before joining to the Union. Empirically, however, in previous EU enlargements members have attracted a significantly higher number of investments compared to the period before membership. However, the analysis of economic indicators of freedom, global competitiveness, of doing business, credit ratings and Turkish investment in the European countries during 21st century found that EU membership is not a decisive factor. As a new member, Croatia did not have the role of mediation towards Western countries because Turkey had been present in the Western market before, and investments did not tend to expand business towards Western countries. The investments were mostly brownfield and closely related to Croatia as a tourist destination. The reasons for investing in Croatia can be found in Turkey's economic expansion policy towards Western, Southeast and Eastern Europe and Central Asia, and such a policy is closely related to Turkey's monetary and economic policy and the aid that state gives to its legal entities if they invest abroad.
