China said it attended a top-level ministerial meeting at the U.K. AI Safety Summit on Thursday, despite not being listed by Britain among the "like-minded" participants and not featuring in official handshakes or the family photograph.

China's absence sparked questions because it participated in the first day of the two-day summit on the safety of "frontier" artificial intelligence, and Britain declined to say why Beijing was not among those joining the second day's senior meeting.

China's delegate to the meeting, Vice Minister of Science and Technology Wu Zhaohui, was present on Thursday, his ministry said Friday. China's participation in the second-day ministerial meeting has not been previously reported.
