This important new study by one of Korea’s leading historians focuses on the international relations of colonial Korea – from the Japanese rule of the peninsula and its foreign relations (1905–1945) to the ultimate liberation of the country at the end of the Second World War. In addition, it fills a significant gap – the ‘blank space’ – in Korean diplomatic history. Furthermore, it highlights several other fundamental aspects in the history of modern Korea, such as the historical perception of the policy-making process and the attitudes of both China and Britain which influenced US policy regarding Korea at the end of World War II.
