Sun Chenghao, Associate Research Fellow at the Center for International Security and Strategy (CISS) at Tsinghua University, participated in a closed-door seminar on November 18 and spoke as a panelist at a roundtable discussion on artificial intelligence (AI) governance. He emphasized the potential for U.S.-China collaboration in global AI governance, noting the importance of jointly addressing transboundary risks, promoting widely accepted risk assessment frameworks, and exploring collaborative solutions. Sun also highlighted the need for dialogue on AI’s economic and societal impacts, focusing on measures such as education reform, skills transition, and inclusive digital infrastructure to enhance public adaptability. Furthermore, he discussed how AI could be leveraged to contribute to global public governance. During the forum, Sun also gave interviews to media outlets such as the South China Morning Post.

In addition, Sun participated in a side event organized by Strategic Youth, where he provided guidance to student groups on discussion proposals concerning U.S.-China coexistence in the Asia-Pacific, non-traditional security challenges, and global peace and stability, and answered questions on U.S.-China relations, military AI applications, and cultural exchanges.
