US-led probe finds semiconductor firms sold $26.2B in tech to China in 2024, raising national security concerns.

A bipartisan US House investigation reveals that major semiconductor equipment firms from the US, Japan, and the Netherlands have significantly advanced China’s chip industry, with sales to Chinese state-owned and military-linked entities rising to $26.2 billion in 2024. Companies like ASML, Tokyo Electron, and Lam Research earned up to 44% of their revenue from China, despite US export controls. The probe found ongoing sales to firms linked to China’s military and intelligence sectors, with evidence Beijing may be stockpiling restricted lithography equipment. Lawmakers warn these transfers threaten US national security, military superiority, and global technological leadership, urging stronger export controls, tighter component rules, and improved coordination to protect critical semiconductor technology.
