Alibaba and WuXi AppTec Fall in Hong Kong After US Military Blacklist, While Baidu and BYD Shrug Off the Move

Other high-profile names on the expanded blacklist barely flinched. Baidu (09888.HK) edged roughly 0.4% higher in early trading, while electric-vehicle maker Nio also rose . BYD (01211.HK), the EV giant, was among the newly added firms alongside Alibaba and Baidu, but specific intraday pricing on June 9 was not separately reported in the sourced articles .

What the Pentagon’s list actually does

The Department of Defense updated its Section 1260H roster—a list mandated by the Fiscal Year 2021 National Defense Authorization Act—formally designating companies it claims are linked to Beijing’s military-civil fusion strategy . The designation does not automatically impose sanctions or export controls. However, under recent U.S. law, the Pentagon is progressively prohibited from contracting and procuring goods or services from companies on the list .

The updated list now names 188 Chinese companies with alleged military ties, an increase from roughly 130 in the previous edition . The June 9 filing followed a chaotic earlier attempt to publish the list in February 2026, when the Pentagon briefly posted and then withdrew the document from the Federal Register without explanation before this formal June release .

Why WuXi AppTec got hit hardest

The contrasting market reactions point to a clear pattern: companies with substantial U.S. biotech or defense-related revenue streams saw sharper selloffs. WuXi AppTec, which relies heavily on partnerships with American pharmaceutical and biotech firms for contract research and manufacturing, appeared more exposed to the reputational and operational fallout of a military-linked designation.

For Alibaba and Baidu, the pain was far more limited. Many analysts noted that investors had largely priced in U.S. geopolitical risk for large-cap Chinese tech names, which already faced years of investment restrictions and scrutiny under previous administrations. The blacklisting did not materially change their core commercial businesses outside U.S. government procurement.

The muted reaction in some names also suggests a degree of skepticism about the substance of the Pentagon’s allegations. Alibaba and WuXi AppTec each called the designation baseless and erroneous , and the February withdrawal episode had already introduced a perception of uncertainty around the list’s staying power. While June 9 formalized the move, the market had already weathered the initial shock months earlier.
