This paper examines the US-China trade war (2018-2019) and its multifaceted impact on globalization. It explores the causes of the conflict, including China's alleged unfair trade practices and the US trade deficit. The research analyzes the war's consequences on both nations, encompassing economic disruptions, job losses, and agricultural decline. Additionally, the paper investigates the impact on other countries, with some benefiting from trade diversion while others facing economic strain. Finally, the involvement of US multinational corporations (MNCs) is explored, considering their potential support for some trade war goals while opposing increased tariffs that burden their operations.
