Ethnopolitical processes as determinants of ethnopolitical management in Eastern European countries in the context of sub-regional security

The following article discusses ethnopolitical processes (politicization of ethnicity and ethnopolitical mobilization of national and ethnic minorities) in Eastern European countries. The author analyses social and political activity of national and ethnic minorities, as well as their representation in state authorities of the Republic of Belarus, Republic of Moldova and Ukraine, and concludes that those processes affect the national security of the countries that make up the sub-region. Particular threat to national security is posed by organized separatist actions. In case of the Republic of Belarus, the problem is not observed, but in the Republic of Moldova (Gagauzia, Transnistria) and Ukraine (Donbas, Carpathian Ruthenia) it is a very serious issue. Separatist tendencies of various ethnic groups have a significant impact on the national security policy. They also call for intervention by state authorities, not only in connection with security issues, but also in relation to appropriate management of ethnopolitical processes within the country.
