Abstract In this article, we present an analysis of how East Asian states (specifically, Japan, South Korea and Taiwan) are adapting to the emerging geopolitical contexts of the ‘great powers competition’ between the United States and China. To the extent that the previous literature on GPN/GVC governance included the state as one of the extra-firm actors, geopolitics has not been explicitly dealt with in its role in shaping GPN/GVC governance. We build on the existing research on GPN/GVC governance and propose a shift in perspective, from one of cost-driven to diplomacy-driven governance. Taking the case of the semiconductor industry, we conduct an analysis of native language sources and examine how regulatory supply chain controls are shaping East Asian industrial and trade policies. Specifically, we focus on how East Asian states are negotiating their dependence on the world’s two largest markets, the United States and China, and developing new policy strategies in order to navigate the dual hegemony. The analysis reveals that, while varying strategies are adopted, multilateral alliances of the states are gaining prominence in GPN/GVC governance. We conclude that a more state-centric analysis of GPN/GVC is in order.
