Western policymakers are struggling to meet this challenge. While there is much potential for good in a self-confident China that is willing to invest in the global commons, there is no guarantee that the country's growth and modernisation will lead inexorably to democratic political reform. This Adelphi book examines the political, historical and cultural development of China's cyber power, in light of its evolving internet, intelligence structures, military capabilities and approach to global governance. As China attempts to gain the economic benefits that come with global connectivity while excluding information seen as a threat to stability, the West will be forced to adjust to a world in which its technological edge is fast eroding and can no longer be taken for granted.
