Book excerpt: Cyber issues are of utmost importance and sensitivity for US-China relations today. The combination of cyber and politics is also developing from 'low politics' to 'high politics'. This book discusses cyber politics in US-China relations from four distinct aspects: first, the overall analysis of the role and manifestation of cyber politics in international relations from a theoretical perspective; second, the main issues regarding cyber politics in US-China relations; third, the factors influencing cyber politics in US-China relations; and fourth, the prospect and practice of cyber politics in US-China relations.Based on an exploration of issues in cybersecurity, cyberspace governance, ideology and the power tussle in cyberspace between the US and China, as well as an analysis of the factors influencing cyber politics in the bilateral relations from the perspectives of strategy, discourse, and trust, this book asserts that cyberspace is rapidly becoming a new arena for the geopolitical games between the US and China. A new form of cyber geopolitics is thus emerging.
