Alibaba and Baidu shares tumbled in Hong Kong trading after being briefly listed in a Pentagon report targeting companies linked to China’s military. The U.S. Department of Defense released an updated Section 1260H blacklist on Tuesday, which included the two tech giants alongside electric vehicle maker BYD, before abruptly withdrawing it minutes later. Despite the list’s retraction, Alibaba fell 3.6%, Baidu dropped 5.5%, and the broader index declined 0.5%, reflecting investor jitters over potential sanctions.

The volatility underscores heightened scrutiny of Chinese tech firms amid strained U.S.-China relations. Tencent, already on the blacklist since 2025, also dipped 5.3%. Analysts note that global tech stocks faced additional pressure from concerns over massive AI investments threatening profit margins, a trend that has weighed on U.S. peers like Nvidia. Alibaba’s recent launch of its Qwen3.5 AI model failed to offset fears that aggressive spending could erode earnings.

Market reactions highlight the fragility of investor confidence in Chinese equities. While the Pentagon’s reversal suggests the list may not be finalized, the brief inclusion reignited debates about national security risks and regulatory hurdles. Analysts warn that even speculative links to military ties could trigger further sell-offs, particularly as Washington tightens export controls on advanced technologies.

This episode raises questions about the long-term viability of Chinese tech firms navigating U.S. policy shifts. With AI competition intensifying, companies like Alibaba and Baidu must balance innovation with compliance. For now, the episode serves as a stark reminder of how geopolitical dynamics continue to reshape global markets.
