China Bans DeepSeek Researchers from Travelling Abroad
China now requires AI researchers at DeepSeek and Alibaba to get government approval before travelling. The move treats AI expertise as a national security asse
China has placed sweeping travel restrictions on artificial intelligence researchers and executives, including those at DeepSeek and Alibaba, requiring government approval before they can leave the country. Confirmed on 26 May 2026, the policy treats AI expertise as a national security asset — a dramatic escalation that has sent ripples through the global technology industry.
The restrictions extend controls previously reserved for nuclear scientists and executives at state-owned enterprises into China’s most commercially valuable private-sector AI companies. On the same day the travel restrictions were confirmed, DeepSeek made a 75% price cut to its V4-Pro model permanent.
What China Is Actually Doing
From 26 May 2026, key AI researchers and company founders at private firms must obtain official approval from government agencies before travelling abroad. The rule applies to named executives and researchers — not all employees — but the scope is broad enough to cover the most strategically valuable people in China’s AI sector.
The requirement is framed as a national security measure. China’s government argues that top AI talent carries knowledge equivalent in strategic value to weapons scientists or military engineers.
Why DeepSeek Is at the Centre of It
DeepSeek is not a typical AI startup. Its parent company, High-Flyer, is a Chinese quantitative hedge fund that pivoted into AI research with remarkable speed. DeepSeek’s models — particularly its R1 reasoning model released in January 2025 — caused significant disruption in Western AI markets, demonstrating that high-performance AI could be built at a fraction of the cost of US rivals.
Reports from December 2025 indicated that High-Flyer was already holding certain employees’ passports as an informal enforcement mechanism. The formalisation of that approach into a government-level requirement in May 2026 marks a hardening of state control.
From Passports to Permission Slips
In December 2025, the restrictions were soft — companies holding passports, informal pressure, unwritten rules. By May 2026, the policy has hardened into a formal pre-approval requirement from government agencies.
This means researchers can no longer simply negotiate their way around it with an employer. They must go through a government process — one that can be delayed, denied, or used as leverage — to attend international conferences, visit overseas offices, or accept foreign job offers.
How This Compares to Other Restrictions
Western democracies do not have direct equivalents to this policy. The US has export controls that restrict technology transfers. The UK has the National Security and Investment Act, which allows the government to block foreign investment in sensitive sectors. But neither requires scientists to obtain government approval before travelling.
Some analysts have drawn comparisons to Soviet-era restrictions on scientists working on classified projects. China’s restrictions are narrower in scope but follow similar logic.
DeepSeek’s 75% Price Cut — What’s Behind It?
Also on 26 May 2026, DeepSeek made its 75% price reduction on the V4-Pro model permanent. The model competes directly with OpenAI’s GPT-4 class systems and Anthropic’s Claude 3 family, and was already among the most competitively priced frontier AI models available.
For UK businesses building AI-powered applications, DeepSeek’s pricing makes it an attractive option. But the travel restrictions raise questions about long-term stability. The price cut may reflect a strategy to capture market share aggressively while momentum holds.
What the West Is Watching
The restrictions have drawn attention from AI policy observers across Europe and North America. In the same week, Anthropic and the Gates Foundation announced a joint pledge of $200 million to deploy Claude inside government applications — a model of AI development built on international collaboration, standing in stark contrast to Beijing’s direction.
What This Means for UK AI Businesses
For UK companies that use or licence DeepSeek models, the immediate impact is limited. The models remain available and the price cut makes them more accessible than ever. API access is not affected by the travel restrictions.
UK businesses building products on top of Chinese AI models should factor geopolitical and regulatory risk into their supplier assessments. For UK AI researchers, China’s restrictions are a reminder that talent mobility is a genuine competitive advantage — and one the UK should protect.
