China’s DeepSeek Shows Why Trump’s Trade War Will Be Hard to Win

Abstract

Recent developments in Chinese AI, particularly the DeepSeek-V3 language model, demonstrate significant limitations in US trade restrictions on high-end semiconductor exports to China. While these restrictions aimed to slow Chinese progress in AI for national security reasons, they inadvertently accelerated the development of effective AI systems that don’t rely on cutting-edge chips. DeepSeek-V3, developed by a Chinese hedge fund at a reported cost of only $5.5 million in compute expenses, achieves near-top-tier performance despite using lower-quality semiconductors. This breakthrough reveals that sophisticated AI systems can be built without access to the latest chips, potentially enabling AI development by other nations or even wealthy individuals. The case highlights how trade restrictions can have unintended consequences: while successfully limiting China’s access to advanced semiconductors, they prompted innovations that could make AI technology more accessible globally. These developments suggest that micromanaging global markets through trade restrictions may be increasingly difficult, as rule-evading entrepreneurs often move faster than regulatory bureaucracies. The situation exemplifies the challenge of implementing effective national security policies in practice, even when their theoretical justification appears sound. - AI-generated abstract.
