This chapter considers the intensity of US-China strategic competition playing out within a broad range of Artificial Intelligence (AI) and other emerging security technologies, including cyberspace, semi-conductors, 5G networks, autonomy and robotics, quantum computing, and big data analytics, to name a few. It describes how great power competition is mounting within several dual-use high-tech fields, why these innovations are considered by Washington to be strategically vital, and how (and to what end) the US is responding to the perceived challenge posed by China to its technological hegemony. The chapter uses International Relations (IR) concepts concerned with the nature and distribution of power within the international system, as a lens to view the shifting great power dynamics in AI and related emerging security technologies in the Indo-Pacific region.
