Abstract: The subject of the study is technological sovereignty in the 21st century. The article provides a comparative historical analysis of the concept, features and experience of technological sovereignty from the point of view of representatives of socialist development with Chinese specifics. The research focuses on the main problems of technological sovereignty in the context of globalization of the XXI century. The study deeply examines the definition and significance of technological sovereignty and its unique characteristics in the modern world, including the impact of technological innovations on national competitiveness, security problems caused by technological dependence, as well as the maintenance of sovereignty in international technological cooperation and competition. In particular, the article considers China as a typical case for analyzing its practical experience, problems and coping strategies in building technological sovereignty. Historical, documentary, survey and comparative studies were chosen as the methods of study. The scope of the results and their novelty lies in the awareness of the value of accumulated political and trade experience to protect State security and prevent a new form of war against the background of prolonged globalization and technological revolution, thereby promoting international cooperation and positive rivalry. Conclusions and results. Technological sovereignty means that a country retains its sovereignty and independent status in political, economic, and other fields, independently mastering key technologies and innovative opportunities. It emphasizes the autonomy of the country and the rights of control in the technical field and is an extension and embodiment of national sovereignty in the technical field. The problem of China's technological sovereignty is characterized by distinctive features. On the one hand, China is committed to strengthening independent innovation and increasing technological self-sufficiency in order to get rid of external dependence and restrictions and ensure the security of technological sovereignty. On the other hand, China actively participates in the global governance of science and technology and promotes the creation of an open, cooperative and mutually beneficial international system of scientific and technical cooperation to maintain the balance and stability of the global technological ecosystem. The study of technological sovereignty has given new life to the theory of political science. This encourages political scientists to pay more attention to the impact of technological factors on the global political landscape and international relations, and also promotes interdisciplinary integration and innovation of political science theory.
