There were several reports of citizens filing complaints with authorities after their family members became involved with such groups.

It also estimated that 23.1% practices Christianity, 4% are unaffiliated, and 0.9% of the population practices other religions, mainly Buddhism and Folk Religion.

The foundation of an independent republic, following the disintegration of the USSR, has launched a great deal of changes in every aspect of people's lives. Religiosity of the population, as an essential part of any cultural identity, has undergone dynamic transformations as well. Baptist Churches are often raided.
