The Threat of Economic Deglobalization from Cold War 2.0: A Japanese Perspective

Abstract

The intensified geopolitical tension in Northeast Asia and the U.S.–China confrontation have shifted policy debates in Japan toward national security while the economic discussion has become thin. To regain more balanced policy talks, this paper tries to quantitatively comprehend the effect of the United States and its allies’ export controls on the East Asian machinery production networks and Japan's trade performance. Major findings include the following four points: First, most of the supply chain decoupling policies by the Japanese government have been the ones to prepare for sudden interruptions of the supply of important items while decoupling policies for strategic competition are limited only in the context of the cooperation with the United States. Second, international trade statistics at the industry level do not show clear evidence of supply chain decoupling in East Asia due to the U.S. export controls, at least up to 2022. Third, however, the negative trade effect becomes visible at the product or individual firms’ level, and the recent strengthening of the United States and its allies’ export controls may augment the negative effect on machinery production networks. Fourth, although the scope of trade controls would expand further, the supply chain decoupling is likely to end up with a partial one. The paper claims that middle powers such as Japan must establish a well-balanced trade policy.
