<p dir="ltr">This article seeks answers to the question: how does geopolitical rivalry over strategically important industries impact the design of global supply chains? To answer this question, we examine how high technology firms responded to the United States (US) and Chinese government policies related to protecting national technological competitiveness. The study pays particular attention to how high technology firms moved sources of supply and production sites in response to protectionist government policies, and the new supply chain designs that emerged. The research question is examined through the lens of Resource Dependence, Resource Orchestration and Institutional Theory. A comparative case study design is used to contrast how high technology firms in the semiconductor and rare earth industries have responded to a technological rivalry between the US and China. Twenty-three interviews were conducted with senior managers and supply chain executives working at thirteen semiconductors and eight rare earth metals companies, all of which had operations in the USA, China, or both. The comparative case analysis provides insights into the different actions that companies take to reconfigure their supply chains in response to geopolitical tensions. The study’s findings inform Geopolitical Resource Orchestration and Proactive Disruption Risk Mitigation frameworks, which outline potential mitigation measures that companies and policymakers can take to alleviate the impact of geopolitical tensions on global supply chains.</p>
