In a significant escalation of the tech rivalry, the United States has enacted a powerful new law designed to clamp down on American investment flowing into Chinese technology companies. President Donald Trump signed the annual National Defense Authorization Act (NDAA) into law, which includes provisions granting the government broad authority to monitor and restrict U.S. capital that could bolster China's military and surveillance capabilities.
Bipartisan Push to Cut Off Critical Capital
The move represents the most substantial legislative effort yet to police how American money and expertise reach Chinese firms. Lawmakers from both major political parties have expressed growing alarm that U.S. investments are accelerating Beijing's advances in critical, cutting-edge fields. The new rules specifically target entities in China, as well as Cuba, North Korea, Venezuela, and Russia, that develop "dual-use" technologies with both commercial and military applications.
"Investments propping up Communist China's aggression must come to an end," stated House Speaker Mike Johnson, reflecting the hardened stance in Washington. The NDAA passed both the House and the Senate with large bipartisan majorities, cementing and expanding upon an executive order issued by the Biden administration in 2023.
How the New Screening Regime Will Work
The legislation authorizes the President to use sanctions powers under the International Emergency Economic Powers Act to prohibit Americans from acquiring significant equity or debt in specific Chinese companies. The definition of covered entities is broad, including firms based in China, Hong Kong, and Macau; state-owned enterprises; and companies tied to Chinese Communist Party officials.
The focus is on companies operating in China's defense or surveillance-technology sectors. For deals that are not outright banned, a mandatory government notification will be triggered. This means U.S. companies must report transactions involving sensitive Chinese technologies like artificial intelligence, quantum computing, and advanced semiconductors.
Emily Kilcrease, a director at the Center for a New American Security, noted, "This is the furthest this has gotten in the legislative process." The law adopts an "all-of-the-above" strategy, blending sector-based rules, a sanctions-style entity list, and public-market restrictions to settle a long-running congressional debate.
A Reversal of Decades of Investment Flow
This policy marks a stark divergence from the past two decades, where billions of dollars from U.S. venture-capital firms, pension funds, and endowments fueled the growth of China's tech sector. These investments helped build foundational semiconductor, AI, and hardware companies at a time when Washington viewed such technological engagement as benign.
That history is now under intense scrutiny. Earlier this year, reports highlighted how figures like Intel CEO Lip-Bu Tan channeled U.S. venture capital into Chinese chip makers for decades. Furthermore, major U.S. investment firms like Vanguard, BlackRock, and Fidelity have increased stakes in companies like Alibaba, despite lawmakers' concerns.
Senator John Cornyn, who led the legislative effort, argued forcefully, "Every dollar invested in China by a United States investor into a Chinese company is a dollar that's going toward the potential production of weapons and technology that one day may be used to kill Americans." Echoing the national security imperative, Senator Catherine Cortez Masto emphasized the need for the U.S. to "remain ahead of our adversaries in the race to develop cutting-edge technologies."
The trend of declining U.S. investment into China is already pronounced. According to the Rhodium Group, direct U.S. investment, including venture capital, is at an all-time low after beginning to decline in 2018. Private-sector resistance to these new outbound-investment limits has softened, with many firms already complying with the prior Biden administration order. Congressional staffers suggest the NDAA is unlikely to significantly increase the compliance burden beyond existing measures.
