This report provides an overview of cyber risk reduction terminology and regulatory measures within China, Russia, the United States and the European Union. It finds, among other things, that China and Russia excel at clear visuals and steps, yet they also tend to lack linguistic clarity. China, the USA and the EU possess interagency and public–private sector coordination, while facing jurisdictional overlap. China, Russia, the USA and the EU are securing their supply chains, yet China and Russia face challenges with burdensome penalties for non-compliance, and the USA and the EU confront obstacles to enforcement at the state and member-state levels. This report is intended to provide a baseline for engagement among the four actors to strengthen and deconflict their respective cyber risk reduction approaches. The authors would like to express their sincere gratitude to the German Federal Foreign Office for their generous support of this project.
