The Congress of National Communities of Ukraine (CNCU) is s non-profit non-governmental organization established in 2001.

There are 17 national communities participating at the CNCU programs of: Monitoring of Law Violation Against National Minorities, Publishing Projects, Law Experts Group, National Mass Media Journalists, Education at the National Communities in Ukraine, Children's Camp “Sources of Tolerance”, Monitoring of the Election Campaign in the Context of the Inter-ethnic Relations, Researching of the Ethnic Processes of the Ukrainian Society, Restitution Problems for the Communities. These and other CNCU programs are aimed to unite efforts of the national communities in Ukraine on integration into Ukrainian society and its transformation into democratic and civil one, active advocacy for the tolerance values, equality, mutual respect to the national individualities and values of each representative of the polyethnic Ukrainian people.

The Congress pays much attention to the Children's programs. Annual Children's Summer Camp ‘Sources of Tolerance' was succesfully conducted in years 2002-2005 for 300 young representatives of the 17 national communities of Ukraine (Poles, Jews, Lithuanians, Hungarians, Germans, Romanians, Moldovans, Volga Tatars, Armenians, Ukrainians, Crimean, Tatars, Russians, Greeks, Buelorussians, Bulgarians, Azerbaijanians). Tutors in the camp also belonged to various ethnic cultures. Professional psychologists worked with children. Children are not divided into groups depending on their ethnic belonging, that is why children from different nations don't have to compete with each other and prove which nation is better. Teenagers and tutors study new facts about different cultures and avquire skills of tolerant communication.
