The U.S. Treasury Department has finalized a rule, effective January 2, 2024, prohibiting U.S.-based investors from participating in transactions that could bolster China’s advancement in critical technologies, particularly semiconductors, quantum computing, and artificial intelligence. This regulation, originating from a 2023 executive order by President Joe Biden, marks a strategic tightening of technology controls aimed at curtailing China’s potential military applications and its access to high-caliber technical expertise from the United States.
The rule specifically restricts investments in quantum computing, semiconductors, and AI that could augment military, surveillance, and intelligence technologies in China. Unlike AI and semiconductor transactions, where some investments may proceed if reported, quantum computing transactions face a blanket prohibition. Notably, this directive encompasses not only tangible exports of equipment but also less tangible benefits like managerial expertise, network access, and talent sharing, which the rule identifies as potential indirect advantages that could strengthen China’s competitive standing in these fields.
In line with enforcing the new rule, the Treasury Department has established the Office of Global Transactions within its Office of Investment Security to oversee the Outbound Investment Security Program. Paul Rosen, assistant secretary for investment security, underscored the rule’s goal: preventing U.S. investments from inadvertently accelerating technological advancements in China with potential military repercussions.
The rule, while specific to “countries of concern,” targets entities in mainland China and its special administrative regions of Hong Kong and Macao. Beijing, however, denounced the measure. Chinese Foreign Ministry spokesperson Lin Jian accused the U.S. of attempting to stymie China’s rise as a global power and promised “all necessary measures” to defend China’s interests.
This latest U.S. action comes amid growing unease over how investments in advanced technology could feed into China’s capabilities, particularly in sectors like AI and quantum computing, where Beijing is seeking substantial gains. The RAND Corporation’s Daniel Gonzales highlighted concerns over U.S. venture capital (VC) contributions to Chinese companies developing dual-use technologies, particularly AI algorithms with potential military applications. He pointed to instances like Sequoia Capital’s early involvement with TikTok, which helped develop AI technologies now viewed by U.S. authorities as having possible military applications, exemplifying the need to close loopholes on indirect technology transfers.
Quantum computing stands as a priority for restriction, given fears over its implications for cybersecurity. According to Gonzales, Chinese researchers have focused on quantum algorithms designed to breach encryption protecting U.S. government and financial data. The rule aims to prevent U.S.-based firms from inadvertently enabling China to achieve breakthroughs in this domain, which could, if attained, compromise key U.S. security frameworks.
Experts emphasize that the rule’s effects go beyond financial capital, curbing the transfer of expertise and networks often accompanying these investments. Stephen Ezell of the Information Technology & Innovation Foundation sees the rule as a warning for U.S. firms to “think twice” about aiding China’s technological ambitions, highlighting that the loss of managerial and talent networks could be a particularly potent setback for China’s tech sector.
The broader context is a complex, shifting technological landscape, as BRICS nations and a host of emerging economies explore alternative partnerships and frameworks, potentially positioning themselves outside U.S.-led technology ecosystems. However, for now, Washington’s measures aim to constrain China’s trajectory in military-adjacent technologies by limiting not only the flow of capital but also the crucial expertise that often accompanies such investments. This recalibration underscores the U.S.’s intent to maintain a lead in advanced technologies while stymieing potential threats to its national security posed by technological advancements in geopolitical rivals like China.
