China restricts overseas travel for top AI talent at Alibaba and DeepSeek

China’s government is now telling some of its most valuable AI researchers they can’t leave the country without asking permission first. According to Bloomberg, select professionals at Alibaba Group and DeepSeek must now obtain prior government approval before traveling overseas, a policy targeting startup founders, researchers, and executives working on advanced artificial intelligence.

From state labs to private sector

China has restricted travel for people connected to state-related entities before. What is new is the expansion of these controls into the private sector’s AI operations, which signals just how strategically important Beijing considers the work happening inside companies like Alibaba and DeepSeek.

Bloomberg reported that some DeepSeek executives faced similar travel restrictions back in December 2025. And prior to that, two co-founders of Manus, a Chinese AI startup, were also reportedly barred from overseas travel.

The stated goals behind the restrictions are twofold. First, safeguarding sensitive technology from leaking abroad. Second, accelerating China’s AI development relative to the United States.

What this means for investors

Neither Alibaba nor DeepSeek has commented publicly on the restrictions. No immediate market reaction followed Bloomberg’s report.

For investors with exposure to Chinese AI companies, these restrictions introduce a new category of risk that doesn’t show up on a balance sheet. If top researchers at Alibaba and DeepSeek perceive these travel restrictions as career-limiting, it could trigger a subtle but significant brain drain away from the companies most affected by these controls.

Investors should watch for secondary signals: key researchers quietly leaving affected companies, a slowdown in published research output, or a reduction in these firms’ participation at major international AI conferences.
