Russian language as a means of cross-border education development

The article deals with the issue of reducing the importance of the Russian language in the world. Culture is the total social experience of humanity, and language is a means of accumulating, storing, and transmitting this social experience, scientific and everyday information. It is a means of objectifying human consciousness, the continuity of generations, and their historical experience. Until 1991, Russian was the universal means of interethnic communication on one-sixth of the land. The refusal to learn the Russian language in some post-Soviet republics has led to a decline and even to a drop in the level of education and culture in general. The research aims to analyze the Russian language position as the core of culture and education in the post-Soviet space as a means of cross-border cooperation, development of education, and dialogue of cultures. The study has been conducted for 10 years in the South-East of Ukraine. It seems to us that the language situation in the Donbas can be projected with some degree of similarity to the entire post-Soviet space. To determine the principle of the state language policy of the post-Soviet republics, we used the analysis of Ukraine's legal documents in the period from 1991 to 2020. The presence of a common cultural space and language will help preserve peace and prevent war on the Eurasian continent. The common language space contributes to the development of economic, social, educational, and as a result of geopolitical ties.
