The United States has added several of China’s most prominent technology and industrial companies—including Alibaba, Baidu, and BYD—to its list of firms it believes are supporting Beijing’s military, in a move likely to intensify already strained relations between Washington and Beijing.

The updated designation, released on Monday, broadens the scope of the Pentagon’s so-called “1260H” list, which identifies companies deemed to be contributing to China’s military-industrial development. The revision replaces an earlier 2025 version and comes amid a fragile trade truce following a recent meeting between U.S. President Donald Trump and Chinese President Xi Jinping in Beijing.

The list now captures a wider segment of China’s advanced technology ecosystem, including firms central to artificial intelligence, robotics, semiconductors, and biotechnology. Officials in Washington say the move reflects growing concern that civilian-facing tech companies are increasingly intertwined with China’s military modernization efforts.

Among the additions are chip-related firms such as CXMT and YMTC, robotics companies including Unitree, and biotech group WuXi AppTec, alongside other industrial players like Baicells. The inclusion of such firms signals a shift toward targeting not only traditional defense-linked entities but also companies embedded in emerging technologies.

A spokesperson for China’s embassy in Washington rejected the list, saying Beijing opposes “making discriminatory lists to go after Chinese companies,” and insisting that Chinese firms comply with local laws and regulations. The embassy urged the U.S. to “stop its wrong practice and create a fair, just and non-discriminatory environment for Chinese companies.”

Some firms pushed back strongly against their inclusion. WuXi AppTec said in a statement that its designation was “clearly a mistake” and vowed to take steps to correct what it called an “erroneous designation.”

The updated list also includes changes involving state-linked energy giant China National Offshore Oil Corporation (CNOOC), with some subsidiaries removed while others were added. Officials noted that the company remains under direct government control, underscoring how state affiliation continues to influence Washington’s assessments.

Although the designation does not immediately impose sanctions, it carries significant practical consequences. Starting later this month, the U.S. Defense Department will be barred from contracting directly with listed firms, with broader restrictions on indirect procurement set to follow in 2027. Analysts say these measures could ripple through global supply chains and affect American companies that rely on Chinese components and technology services.

Craig Singleton of the Foundation for Defense of Democracies said the move reflects a broader strategic shift in Washington’s approach to Chinese tech firms. “Washington is no longer treating these as isolated companies. It is treating the entire technology stack as strategically contested,” he said.

The inclusion of major consumer-facing companies like Alibaba and Baidu marks a notable expansion of the list’s scope, signaling that even commercially dominant Chinese tech giants are increasingly viewed through a national security lens.

While the Pentagon maintains that companies on the list can petition for removal, the designation itself often carries reputational consequences, sending a warning signal to U.S. agencies and contractors about engaging with the listed firms.

As geopolitical competition between the world’s two largest economies continues to deepen, the latest update reinforces a clear message from Washington: the boundary between commercial technology and military capability is becoming increasingly blurred.
