# Chip Export Controls Chip export controls are US government restrictions on selling advanced [[Semiconductor]]s — and the equipment and software used to make them — to China. Beginning with a sweeping October 2022 rule and tightened repeatedly since, they bar the export of the most powerful AI [[Graphics Processing Unit]]s, advanced chipmaking tools (lithography, etch, deposition), and related design software to Chinese buyers, and restrict US persons from supporting China's advanced-chip industry. They operate through mechanisms like the Commerce Department's "Entity List" and performance thresholds that define which chips are too capable to sell. ## Why it matters here Chip export controls are the single most aggressive instrument of [[Tech Decoupling]], and they mark a genuine bipartisan turn away from the free-trade consensus — making them a key node in the vault's map of how the right's economic thinking is shifting. **The strategy.** The explicit goal, articulated by the Biden administration's national-security adviser as a "small yard, high fence," is to deny China the compute needed for frontier [[AI Arms Race]] capability and advanced weapons, while preserving ordinary trade. It targets the chokepoints identified in [[Semiconductor Fabrication]]: not just finished chips but the irreplaceable *tools*, on the theory that you can set China's chip industry back years by denying the means of production. The controls leaned heavily on allies (the Netherlands' ASML, Japan's tool-makers) to be effective. **The bipartisan continuity.** Notably, this is one of the few major policies of substantial continuity across the Biden and second Trump administrations — China-hawk consensus overrides partisan reflex. It represents a remarkable break from decades of Republican (and Democratic) free-trade orthodoxy, recasting trade with China as a national-security matter rather than a mutual-gains one. It sits alongside tariffs and the [[CHIPS and Science Act]] in the new economic-nationalist toolkit. **The contested results.** Critics question effectiveness: China has accelerated indigenous chip efforts (Huawei's surprise advanced chip, SMIC's progress), [[NVIDIA]] repeatedly designed compliance-threshold chips to keep selling to China, smuggling and shell-buyer workarounds proliferated, and some argue the controls mainly spur Chinese self-sufficiency while costing US firms their largest market. Whether they buy durable advantage or merely delay — and motivate — Chinese catch-up is the central open debate. ## See Also - [[Semiconductor Fabrication]] — the tool chokepoints the controls exploit - [[Graphics Processing Unit]] — the AI chips at the center of the restrictions - [[Tech Decoupling]] · [[China]] — the broader conflict - [[CHIPS and Science Act]] — the domestic-investment companion policy
