US-China 'Tech Divorce' Accelerates

The U.S. prohibition on federal agencies purchasing semiconductors from targeted Chinese companies like SMIC, CXMT, and YMTC is set to take effect on December 23, 2027. This ban extends beyond just the chips themselves to include products and services that incorporate them, a move projected to have compliance and substitution costs in the billions. The rule is part of a broader strategy driven by national security concerns over potential "backdoors" or malicious code embedded in components from foreign adversaries. In response, China's 15th Five-Year Plan (2026-2030) elevates "technological self-reliance and self-strengthening" to a primary national goal for the first time in at least a decade. The plan prioritizes rapid breakthroughs in key areas like semiconductors, industrial machinery, and foundational software to build a more resilient and self-supporting industrial chain. This state-guided model aims to reduce dependence on the U.S. and other Western nations for critical technologies. The U.S. is concurrently bolstering its domestic industry via the CHIPS and Science Act, which authorizes approximately $280 billion to boost American semiconductor research, development, and manufacturing. This includes $52.7 billion in direct funding and 25% investment tax credits, aiming to revitalize the U.S. share of global chip manufacturing, which has fallen from nearly 40% in 1990 to 12%. Despite U.S. export controls designed to stifle its progress, China's top foundry, SMIC, is reportedly developing a 5-nanometer class process. This effort, backed by government support and technical assistance from Huawei, is geared toward producing high-performance AI chips for domestic giants like Huawei, Alibaba, and Tencent. Huawei, in particular, has become the de facto leader of China's semiconductor national team, driving innovation and integrating the domestic supply chain. U.S. export controls, which began escalating in October 2022, now restrict the sale of advanced manufacturing equipment, design software (EDA), and even access for U.S. persons to support China's advanced chip fabs. These actions have forced mass resignations of American workers from Chinese semiconductor firms and blocked access to critical equipment from suppliers like ASML, Lam Research, and Applied Materials. China is aggressively working to close its internal technology gaps by mandating that domestic chip manufacturers use at least 50% locally produced equipment when building new facilities. The country's largest equipment maker, Naura, is already testing advanced etching tools at SMIC's 7nm production line, aiming to replace foreign suppliers. This push is supported by massive state investment, with a "Big Fund" designed to achieve around 50% self-sufficiency in semiconductor equipment by 2025. The tech rivalry extends beyond hardware to talent, with Chinese tech giants like ByteDance and Baidu actively recruiting high-level AI and semiconductor experts in U.S. tech hubs. This hiring spree is intended to build up skilled workforces in AI systems and chip design to compete globally. This occurs as both nations increasingly view data security and technological leadership as central pillars of national security.
