Abstract
The chapter outlines the development of the EU’s cyber diplomacy and links it to the recent policy papers on the Indo-Pacific. Cyber diplomacy needs an all-in approach, accelerating cooperation to meet the challenges of cyber at the nexus of security and technology. It can make an essential contribution to strategic autonomy. Prime partners are in the Indo-Pacific in promoting digital governance and standard setting, to assure a global, open, free, stable and secure cyberspace for continued prosperity and protection of fundamental human rights in cyberspace. Cyber diplomacy fulfils three major functions: it supports externally the EU’s internal policies; protects the interests of the EU and the relevant stakeholders; and gives the EU through the Cyber Diplomacy Toolbox an offensive instrument to defend its interest more effectively. South Korea has an interest to participate in multilateral restrictive measures/sanctions especially when faced with attributable attacks by major forces.
