The relevance of the appeal to the study of the development of culture on a global scale is due to the fact that in the modern period no people or region or country can exist in isolation. In the face of the latest challenges of globalization (the pandemic, the environmental crisis, the threat of man-made disasters, etc.), all countries must join forces in solving world problems. The author proposes a structural-systematic approach to the analysis of the essence of the phenomenon of culture. Hence, the goal of the research is to analyze culture as a complex structured system. In the article, culture is considered by analogy with the "iceberg culture" model, consisting of different layers. The author's attention is focused on the analysis of the process of forming the upper (world) layer of human culture. This layer of culture is a system of ideas, ideals, knowledge, norms and values that are accepted by most countries of the world. The adoption of this system of meanings of the world culture is an important step towards overcoming intercultural communication barriers. Thus, the author draws attention to the fact that although since ancient times the countries of the Black Sea region have been united by a common cultural history, political and trade and economic ties, nevertheless, barriers for mutual understanding have not been eliminated yet. Therefore, today it is very important that all the peoples realize the need to find ways and technologies to form a common language of the world culture.
