MI5 Warns China Is Using UK Academics to Steal AI and Spy Tech

Britain's MI5 spy agency has issued an unprecedented public alert warning that more than 100 UK-based academics have been helping Chinese intelligence services advance their spying capabilities through seemingly innocent university research projects. It is the first time the Security Service has ever independently published an espionage alert of this kind.

Whitehall, London: Security Minister Dan Jarvis has written to every UK university vice-chancellor telling them to end arrangements with the Chinese institute.

The Alert: What MI5 Found

In its "Espionage Alert," published on Wednesday, MI5 said the academics had contributed to projects funded by the China General Technology Research Institute (CGTRI), sometimes translated as the China Academy of General Technology (CAGT). The agency said the institute has "very strong ties" to China's Ministry of State Security (MSS), Beijing's civilian intelligence service.

"MI5 has identified that the primary purpose of CGTRI is to fund academic research that directly improves MSS technical capability for espionage," the alert said. "UK academics have contributed to CGTRI-funded projects on topics including Artificial Intelligence (AI), cybersecurity, covert communications systems and steganography. This activity supports MSS espionage, which poses a threat to UK national security."

Steganography is the practice of hiding information within messages or objects, a technique long associated with covert intelligence work.

According to The Times, academics from Russell Group universities — Britain's most prestigious research institutions — are understood to have been involved in projects linked to CGTRI, usually through collaborations between Chinese and British universities.

MI5 says more than 100 UK-based academics, including researchers at Russell Group universities, contributed to projects funded by the China General Technology Research Institute.

Background: A Growing Pattern of Accusations

The alert is the latest in a series of British accusations concerning Chinese espionage activities, each one adding to the strain between security officials and ministers pursuing closer economic ties with Beijing. MI5 noted that the warning highlights that tension directly.

It follows a difficult episode last year, when a high-profile spy case collapsed after the government refused to formally designate Beijing as a threat to national security, a decision that drew sharp criticism from security-minded MPs. Beijing, for its part, has consistently denounced the allegations as unfounded and pure fabrication.

A Front for Beijing's Spies

MI5 was careful to stress that many of the academics and institutions caught up in the scheme are likely to have engaged with CGTRI in good faith, without any knowledge of its links to Chinese intelligence. The institute is believed to have presented its funding as legitimate academic collaboration.

But the agency left no room for doubt about what happens next. Anyone who continues working with the group now risks prosecution under Britain's National Security Act, which was passed in 2023 to give the authorities greater powers against foreign spying and hostile state activities. Specifically, continued collaboration could fall under offences relating to assisting a foreign intelligence service or obtaining a material benefit from one.

The MSS, China's main intelligence agency, is estimated to have a workforce running into the hundreds of thousands of people, according to The Times, making it one of the largest intelligence services in the world. Beijing has denounced previous British espionage allegations as unfounded and pure fabrication.

The Government's Response

Security Minister Dan Jarvis has written to all university vice-chancellors across Britain, telling them to ensure their staff end every arrangement with CGTRI and comply with the National Security Act.

"This alert exposes attempts by Chinese intelligence to covertly benefit from the expertise and research of our academics, undermining our national security, and that of our allies," Jarvis said. "I have written to all university Vice-Chancellors to ensure they support their staff to end all arrangements with this company."

Universities UK and the Russell Group both responded by affirming that universities take their national security responsibilities seriously and are committed to working with the government and security services to manage risks.

The alert lands at an awkward moment for the government, highlighting the tension between British security concerns and moves by ministers to build closer ties with Beijing. According to reports, it is likely to renew calls from some MPs for China to be placed alongside Russia and Iran in the highest tier of the UK's foreign influence threat framework — a step the government has so far resisted. Last year, a separate spy case collapsed after the government refused to formally designate Beijing as a threat to national security.

MI5 says the funded research covered artificial intelligence, cybersecurity, covert communications systems and steganography.

What This Means

The alert represents a significant escalation in how Britain talks about Chinese espionage. By publishing its first-ever public espionage alert, MI5 is signaling that academic collaboration has become one of the front lines in the contest over emerging technology — and that universities, long prized for their openness, are now treated as a national security vulnerability.

The episode also exposes a difficult trade-off. British universities are among the best-funded and most collaborative research institutions in the world, and international partnerships — including with Chinese scholars — have produced major scientific advances. The government's message now is that openness has a limit, and that researchers must scrutinize the true source of foreign funding.

For the academics involved, the stakes are now legal as well as reputational. The National Security Act gives prosecutors tools that did not exist a few years ago, and MI5's public naming of CGTRI removes any plausible claim of ignorance going forward.

What Happens Next

Vice-chancellors have been told to act quickly, and compliance reviews are expected across research-intensive universities in the coming days. Researchers with current or recent CGTRI-linked funding are likely to be contacted by their institutions' security teams.

The bigger question is diplomatic. Beijing has consistently rejected espionage allegations, and its response to this latest alert is expected within days. Whether the government follows through by elevating China's status in its foreign threat framework will be watched closely in Westminster — and in capitals across the West, where similar concerns about research security are growing.
