The monograph provides knowledge on the complex nature of both external and internal determinants influencing foreign policies of East Asian countries. Through a range of case studies on Japan, China, Taiwan and North Korea, the authors analyze international relations in East Asia as a mosaic of intertwining processes of globalization and regionalization, interests of global and regional powers, local social and economic conditions, national institutional arrangements, and even personal factors. They argue that sometimes a sudden change of one small element in this mosaic suffices to influence the whole system. Instead of providing a simplified interpretation of the analyzed processes, the monograph tries to illustrate them in their entire complexity.The author concentrates in the paper on the trade and financial relations between the United States of America and People’s Republic of China over the period 2005–2015. The growing interdependence of the two leading economies on the Western (the US) and Eastern (China) hemispheres undoubtedly is a salient factor in global economy that needs to be scrupulously studied. The geoeconomic competition between the two states overlaps the concomitant geopolitical rivalry. It is one of the most germane phenomenon in the global economic and political relations of the contemporary world
