US finalising rules to curb investment in China’s AI and defence tech

Effective from 2 January, the regulations will be overseen by the newly established Office of Global Transactions within the Treasury.

US export controls aim to limit China’s technological progress while safeguarding critical advancements.

The Biden administration announced on Monday new rules restricting US investments in specific technology sectors in China, including AI, semiconductors, and quantum computing, citing national security concerns. These rules, effective from 2 January, aim to prevent US capital and expertise from aiding China’s development of military and intelligence capabilities. Issued under an executive order from August 2023, the regulations will be managed by the Treasury’s new Office of Global Transactions.

The targeted technologies are considered crucial to future military and cyber defence. Treasury officials note that US investments often include more than money—managerial support, network access, and intellectual expertise—that could benefit Chinese advancements in sensitive sectors. A senior Treasury official, Paul Rosen, emphasised that these restrictions curb potential US involvement in developing cutting-edge technologies for adversarial nations.

The US Commerce Secretary Gina Raimondo has previously highlighted the importance of these measures, viewing them as essential to slowing China’s progress in military technologies. The new regulations allow for investments in publicly traded Chinese securities; however, existing rules still restrict transactions involving certain Chinese firms deemed to support military development.

Additionally, the rules respond to recent criticism from the House Select Committee on China, which has scrutinised American index providers for funnelling US investments into Chinese companies linked to military advancements. With these regulations, the administration underscores its intent to protect US interests by limiting China’s access to critical technology expertise and capital.
