The idea that countries can pursue prosperity and security as separate streams of the national interest has passed. Economics and security have always been enmeshed, although we assumed otherwise. The nature of the relationship between the two is changing fast. The narratives that surround the change find it difficult to keep up with the facts. The world has become more multipolar, with remarkable growth outside the established powers in the North Atlantic. At the same time, digital technology has not just transformed products, firms and markets, it has opened them to cyber disruption and attack, resulting in a cross-over of security into the economic and social domains. This issue of the East Asia Forum Quarterly explores what is happening, why and how to respond to the change. These essays argue for careful thought and active engagement by governments, business and the broader community. Genuine dialogue and problem-solving between the economic and security parts of universities and government is a good first step to frame the problem broadly, keep perspective and find solutions.
