The Culture of Peace, a concept and set of initiatives proposed by UNESCO in the aftermath of the Cold War, aims to advocate for the cultivation of peace through dimensions such as individual mindsets and behaviors, social inclusiveness, and the relationship between humans and nature. It represents a “cultural theory of peace” that differs from the “power-based theory of peace,” “institution-based theory of peace,” and “community-based theory of peace.” Under the advocacy and promotion of UNESCO, the Culture of Peace has been deeply integrated into the collective agenda of the United Nations. It has gained recognition and been put into practice across the entire UN system, with a growing focus on dialogue among civilizations. Moreover, the Culture of Peace has exerted a profound influence on the UN’s peace agenda through the subtle process of “acculturation,” with two key shifts: a conceptual transition from “negative peace”  to “positive peace”; and a paradigmatic shift from peacekeeping as a security-focused practice to peacebuilding as a multi-dimensional endeavor that integrates development, human rights, gender equality, youth empowerment, and other areas. As the international community looks ahead to the post-2030 global agenda, the role of culture in shaping peace will receive greater attention from the international community. The four global initiatives put forward by China, particularly the Global Civilization Initiative, embody significant implications related to the Culture of Peace. They are well-positioned to contribute to enriching the Culture of Peace and can play a pivotal role in guiding and shaping the future UN peace agenda.
