Abstract: This paper introduced the current status of international cooperation in nuclear security under the cooperation framework among the United Nations, the International Atomic Energy Agency, the European Union, NATO, and relevant international initiatives. The main characteristics and existing problems of current international cooperation in nuclear security are analyzed. Research shows that the international cooperation model led by the US in nuclear security would gradually fail in the post nuclear security summit era, and the enthusiasm of international cooperation in nuclear security has significantly decreased. The concept of a community with a shared future for human nuclear security advocated by China is an innovation in the concept of international cooperation in nuclear security, fully considering the demands of both nuclear and non nuclear countries and focusing on fundamentally solving the problems faced by nuclear security and the threat of nuclear terrorism, is conducive to the sustained and healthy development of international cooperation in nuclear security.

Key words: nuclear security, international cooperation, nuclear terrorism
