MI5 is warning about research collaborations linked, according to the British agency, to the China General Technology Research Institute (CGTRI). MI5 attributes funding to the Chinese body for projects that, in its assessment, enhance the technical capabilities of China's Ministry of State Security (MSS). More than 100 academics with links to the United Kingdom are said to have participated in relevant projects through CGTRI.
The public notice was issued on 30 September 2026. MI5 states that CGTRI's main purpose is to fund research that, in its assessment, enhances the technical capabilities of the MSS for espionage. The official MI5 notice advises British universities to immediately review their collaborations with the organization.
The projects it names cover areas such as artificial intelligence, cybersecurity, covert communication systems and steganography, the hiding of information within other files or messages. MI5 warns that some researchers may not have known who was behind the funding of their projects.
Why MI5 is warning about CGTRI
MI5 claims that CGTRI has “very strong links” to MSS, China’s civilian intelligence agency. According to the notice, more than 100 individuals affiliated with British universities have contributed to research projects funded through the agency.
The reference to dual-use technology areas is particularly relevant to the case. Tools in artificial intelligence, secure communications and cybersecurity can support legitimate scientific progress, but MI5 believes that specific projects offer operational benefit to the Chinese intelligence service.
Reuters reported that MI5 described the move as unprecedented, as it was the first time the agency had independently issued such a notice. The wording reflects the assessment of British authorities; it does not in itself amount to a judicial judgment on any researcher or university.

The Chinese side rejects the accusations
China's embassy in London rejected the allegations, calling them "fantastical and completely fabricated," according to Reuters. A spokesperson also said such reports undermined educational exchanges and cooperation between the two countries.
MI5 acknowledges that universities and scientists may have collaborated with CGTRI in good faith, without knowing the links it attributes to the organization. The BBC reported that Universities UK, the association of British higher education institutions, is reviewing the notification and the potential impact on collaborations.
The public debate therefore concerns a specific entity and specific projects, not the entirety of international scientific collaborations. Maintaining this distinction is important, as the relevant announcements include both MI5's assessment and the clear denial by the Chinese side.
What are universities required to check?
MI5 is warning institutions to review any active or planned collaboration with CGTRI. It is also asking researchers to verify the ultimate source of funding when initiating collaborations with organizations in China to identify any involvement by this entity.
The notice refers to the UK National Security Act 2023 and advises anyone pursuing a project ultimately funded by CGTRI to seek independent legal advice. The recommendation concerns the assessment of specific collaborations and does not in itself constitute a finding of illegality for the participants.

The practical issue for universities is to know who is funding each project, who ultimately receives its results and whether the terms of collaboration are transparent. The origin of funding needs to be examined alongside the partners and the data being shared.

MI5's warning is part of a wider debate about protecting research from state interference, without negating the value of international scientific cooperation. For the European cybersecurity community, the case highlights the need for funding scrutiny and clear due diligence procedures.

The official notice asks institutions to limit the risk from this funding relationship, not to indiscriminately cut off contacts with researchers in China. Careful verification of collaborations and identification of real funders is the central message of MI5.
