Consider the following countries : 1. Armenia 2. Azerbaijan 3. Croatia 4. Romania 5. Uzbekistan Which of the above are members of the Organization of Turkic States ?

Azerbaijan and Uzbekistan are full members of the Organization of Turkic States (OTS), a grouping of nations sharing Turkic linguistic and cultural heritage that also includes Turkey, Kazakhstan, and Kyrgyzstan. Armenia is excluded due to long-standing geopolitical conflicts with member states, while Croatia and Romania are European nations without Turkic ethnic roots. The question tests knowledge of regional intergovernmental organizations and the "Turkic World" identity, which gained significant diplomatic momentum following the organization's rebranding in 2021.
