The article discusses the topical issue of using language as a socio-cultural tool, "soft power", a key factor in integration and interstate interaction at the international level, and the legal regulation of its use. The article analyzes the role of language in shaping the national identity of Russian society and its legal system, preserving spiritual and moral values and strengthening a unified legal and cultural space at the international level. In the article, with specific examples, it is noted that language becomes the object of ideological struggle and ma-nipulation, which actualizes the need to develop mechanisms for its protection at the legislative level and to protect society from threats associated with the loss, distortion or displacement of the native language. The authors consider language as an important part of the culture of the people, the "soft power" of cultural integration, as a relay of spiritual and moral values of soci-ety at the international level. The authors conclude that language, as a socio-cultural tool, is not only a tool for preserving historical memory and traditions, but also an important resource for international dialogue and cooperation. The legal protection and development of the Rus-sian language at both the national and international levels is not only a cultural and humanitar-ian task, but also a matter of geostrategic importance for the preservation of Russian statehood and national identity.
