This book represents the very first comprehensive work that examines Korea-US-China trilateral relations through a strategic triangular lens. It moves beyond conventional discussions of bilateral ties to provide an in-depth analysis of the complexity, conflict, and economic interdependence characterizing the relationships among these three nations.This book takes a fascinating approach by delving into how Xi Jinpings personality and traits influence Chinas decision-making and, in turn, affect the trilateral relationship between Korea, the U.S., and China. This angle is particularly compelling because it personalizes international relations, grounding geopolitical shifts and strategies in the individual characteristics of a key world leader. By examining Xi Jinpings personal impact, this book can offer insights that differ from traditional analyses focused more on economic or military metrics. This unique perspective could indeed attract readers interested in understanding the nuanced ways in which individual leadership styles impact global politics.
