MI5 alert tells UK universities to review ties with Chinese institute it links to state security

MI5 published a "Security Service Espionage Alert" on Wednesday 30 September 2026 saying that the China General Technology Research Institute (CGTRI) "has very strong ties to the Chinese Ministry of State Security (MSS), China's civilian intelligence and security service", and telling UK universities to review any work with it.

What the alert says

The alert is a one-page document published on MI5's website. Its central claims, in MI5's words:

• "MI5 has identified that the primary purpose of CGTRI is to fund academic research that directly improves MSS technical capability for espionage."
• "MI5 has identified that more than 100 UK-linked academics have contributed to projects funded by MSS via CGTRI."
• "In some cases, academics may not be aware that CGTRI is funding the Chinese research project they are contributing to."
• UK academics "have contributed to CGTRI-funded projects on topics including Artificial Intelligence (AI), cybersecurity, covert communications systems and steganography". Steganography is, as Reuters puts it, "the practice of hiding information within messages or objects".

AI is one of four research areas the alert names, alongside cybersecurity, covert communications and steganography. The alert does not say how many of the projects, or which, concerned AI.

The alert also says the institute is "sometimes translated as China Academy of General Technology (CAGT)". According to Reuters, MI5 said this was the first time it had independently published an alert publicly.

What universities are asked to do

MI5 says "Many academic institutions and individuals will to date have engaged with CGTRI in good faith given CGTRI's obfuscated links to MSS." Its expected actions are:

• UK academic institutions "are strongly advised to immediately review any ongoing or planned collaboration with CGTRI".
• Academics "are advised to establish the ultimate funding source when conducting any research collaboration with Chinese institutions, to ensure CGTRI is not involved."
• When scoping collaborations, institutions should use the government's Research Collaboration Advice Team and the National Protective Security Authority's Trusted Research guidance, "and consider taking their own independent legal advice."

The National Security Act point

The alert says that through it "MI5 has placed the fact that CGTRI has very strong ties to MSS in the public domain." It tells institutions, staff and researchers to be aware of the National Security Act 2023, "particularly offences under section 3 (Assisting a Foreign Intelligence Service) and section 17 (Obtaining a Material Benefit from a Foreign Intelligence Service)."

The alert sets out that a section 3 offence involves conduct "likely to materially assist a Foreign Intelligence Service in carrying out UK-related activities", where the person knows, or "having regard to other matters known to them ought reasonably to know", that their conduct is likely to do so. It adds that anyone "continuing to conduct research ultimately funded by CGTRI following publication of this espionage alert should take their own independent legal advice". Reuters and Al Jazeera reported this as meaning that those who carry on working with CGTRI now risk prosecution under the Act.

The government's response

Security Minister Dan Jarvis said he had written to all university leaders to ensure staff ended any relationship with CGTRI, Reuters reported. In a statement quoted by Reuters, he said: "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." He added: "International partnerships are vital to ensure our universities and research institutes continue to thrive, but we will take robust action to defend against the threats we face."

Science and innovation minister Chris McDonald, quoted by Times Higher Education, said international collaboration will "always be crucial" to UK research, but "We can't ignore the risks".

China's response

China's embassy in Britain described the allegations as "imaginary and purely fabricated", Reuters reported. An embassy spokesperson said: "We firmly oppose such baseless allegations and have lodged solemn representations with the UK side," and added: "We urge the UK intelligence authorities to stop spreading falsehoods and stop undermining educational exchanges and research cooperation between China and the UK."

The universities' side

International Business Times reported that Vivienne Stern, chief executive of Universities UK, said the sector had invested in due diligence, risk assessment and research security, and that Russell Group chief executive Libby Hackett said its universities take their national security responsibilities seriously. Both are as paraphrased in that report.

Why it matters

On our reading, the practical change is the one MI5 itself names: the CGTRI link is now on the public record, and the alert says anyone who keeps doing research ultimately funded by CGTRI after publication should take legal advice under the National Security Act. For AI researchers, the alert's direct ask is to check where collaborative funding ultimately comes from. MI5 lists AI as one of several fields involved, does not say how much of the work concerned it, and does not name any UK universities or academics.
