This class is designed as an introductory course to diplomacy, focusing on "What is diplomacy?" (the subject of study) and "How is modern diplomacy conducted?" These two questions are answered by considering the changing nature of diplomacy in line with global changes. The advent of the digital era, where technology enables broader and cheaper access to cross-border communication media, has given rise to and empowered new actors who carry out diplomatic practices previously carried out solely by state diplomats. Today, state diplomats are rarely alone in the negotiation room, and are more often accompanied by other actors from the business sector, civil society organizations, academia, and others. Does this mean the end of traditional diplomacy?
