This article illustrates the nature and significance of information sovereignty in the expanding BRICS regions. The study adopts an approach that considers sovereignty as an integral system of political and legal relations, institutions, and values. Its main components include technological and ideological elements. In the context of growing global information challenges and threats, it is necessary to implement a targeted state policy to ensure information sovereignty for BRICS member states and their joint efforts to defend the interests of the global majority. To ensure information sovereignty, it is necessary to combine the tools of the so-called “information shield” and “information sword” in the information policy. BRICS serves as a communication platform that facilitates the effective exchange of best practices. As an expanded format, BRICS can make greater use of the advantages of “soft power,” which affirms the legitimacy of decisions by garnering the support of representatives of developing countries. BRICS has significant potential in the field of coordination and the formation of common principles and approaches to the implementation of information sovereignty. It also allows for the expansion of a common approach by involving developing countries in cooperation and extending the norms and rules of information sovereignty to the countries of the global majority.
