The Korea Times discusses how diplomacy, long used to negotiate and manage relations among states and other actors, is adapting to the shift from the digital era to the AI era. It describes diplomacy as a core tool for communication and negotiation: during peacetime, it helps consolidate stability and cooperation, while in wartime it supports efforts to prevent escalation and aid restoration of peace. The article outlines major categories of diplomacy—state diplomacy, which covers official foreign affairs; public diplomacy, which advances the interests and values of public and private groups by engaging foreign publics; and personal diplomacy, which serves the interests of individual leaders. Against this background, it argues that the growing role of artificial intelligence is changing how diplomacy operates, and that traditional diplomatic practices are no longer fully sufficient in an environment shaped by AI-driven capabilities. The piece frames the issue as an evolution in the practice and purpose of diplomacy across different actors and channels, reflecting the need to communicate and negotiate effectively in new technological conditions.
