This edited volume explores the past, present, and future of the Korean Peninsula, with special focus on South Korea, by connecting developments in politics with those in international relations and diplomacy.The book focuses on how South Korea’s politics and international relations have evolved since the founding of the First Republic in 1948, with particular attention to the period surrounding the 2022 presidential election. The authors provide new insights into Korean politics, including South Korean electoral reform and relations with China and Japan, North Korea’s nuclear capacity, and North-South diplomacy.Beginning with a commentary by Colin Crooks, Britain’s current Ambassador to South Korea and former Ambassador to North Korea, on recent British foreign policy changes and UK-Korea relations, this book will appeal to scholars and students of politics, international relations, diplomacy, and Korean Studies.
