This paper analyzes China’s words and actions regarding the Nuclear Security Summits to better understand what Chinese leadership on nuclear security could look like in the future. It finds that China accomplished the many things it said it would do during the summit process. The paper also explores how China’s policy and actions in other nuclear arenas could be paired with Chinese nuclear security policy to form a coherent agenda for nuclear risk reduction writ large. Consequently, the paper addresses how China doing as it says and does – per nuclear security – may be used as a way in which to inform its future nuclear security roles and responsibilities. In particular, it assesses China’s opportunities to assume a leadership role within this crucial international security issue area, especially at a time where U.S. leadership has waned.
