This paper explores the challenges of Generative AI technologies to China’s diplomatic engagement worldwide. First, it examines the discourse in China about the development of ChatGPT, by focusing on the treatment of the technology and the possible risks and opportunities regarding international affairs. Second, the article highlights four challenges: (1) the securitization of AI, where import/export controls, data access, and semiconductors open a new field of research; (2) the (techno-) socialism with Chinese characteristics and the response to the arrival of cutting-edge technologies from U.S. capital and their impact on the development of a local model; (3) the soft censorship: the development of a technology that responds in the "correct" way (i.e., in line with the ruling ideology) by discriminating the suitability of sources/data deemed correct and appropriate for the public sphere; (4) the impact on public diplomacy, as AI projects an aura of innovation and technological reputation. In summary, this paper contributes to the theoretical debate on the challenges posed by Generative IA technologies in the context of China’s diplomatic practices.
