Abstract: The strategic convergence of China's diplomacy and national security in the new era has shaped the distinctive security implications of major-country diplomacy with Chinese characteristics. Amid profound changes unseen in a century, it is necessary both to adopt a holistic approach to national security to provide strategic guidance for major-country diplomacy with Chinese characteristics, and to make major-country diplomacy with Chinese characteristics a paradigmatic extension of that approach in the international dimension. Majorcountry diplomacy with Chinese characteristics embeds civilization, development, openness, and governance within security, giving rise to a new type of security thinking characterized by exchange and mutual learning, equality and independence, inclusiveness and sharing, and fairness and justice. The global security contribution of majorcountry diplomacy with Chinese characteristics is rooted in its shaping of the practices, concepts, knowledge, and values of global security. It rests on four dimensions: the developmentoriented building of independent capabilities, the conceptual framework of a community with a shared future for humanity, a knowledge paradigm that breaks cognitive hegemony, and the thread of the common values of humanity. It is committed to advancing the international order toward greater equity and rationality. The security implications of majorcountry diplomacy with Chinese characteristics reveal a key strategic dimension of the effort to build a community with a shared future for humanity.

Key words: major-country diplomacy with Chinese characteristics, a holistic approach to national security, global security, a community with a shared future for humanity
