The term is being used to refer to different aspects, including the country's policymaking process, its development of artificial intelligence and scientific instruments, and its military strategy. The meaning and implications of the "black box" label appear to vary across different reports and fields, with some outlets using it to discuss specific technologies or policies, while others use it more broadly to characterize China's overall approach.
