Major Security Warning: MI5 Urges UK Universities to Cut Ties with China

By the Editorial Team · Thursday, October 1, 2026

MI5 has warned British universities to cut ties with Chinese organizations linked to espionage, specifically targeting researchers funded by the China General Technology Research Institute, an MSS front involved in sensitive technical fields. The government is threatening legal action under the National Security Act to prevent foreign intelligence exploitation of UK academic research, emphasizing national security risks within higher education.

The United Kingdom’s domestic intelligence agency, MI5, has issued a public warning urging British universities to sever links with Chinese entities involved in sensitive research due to concerns over espionage. The alert focuses on academics receiving funding from China's Ministry of State Security (MSS), which MI5 alleges is using research projects to enhance its technical capabilities for intelligence gathering.

MI5 identified approximately 100 British researchers who have accepted support from the China General Technology Research Institute (CGTRI), a front organization linked to the MSS. The research areas of concern include artificial intelligence, cybersecurity, covert communication systems, and steganography—the practice of concealing messages within files or objects. According to MI5, the primary purpose of the CGTRI is to advance technical expertise directly benefiting Chinese intelligence activities.

Although MI5 has not publicly named the universities involved, investigations have found that Cambridge University published a 2025 study co-authored by one of its academics and funded by the China Academy of General Technology (CAGT), another name used for CGTRI. The research focused on "ancient metagenomics," which involves analyzing DNA from archaeological samples. Additionally, two University College London (UCL) researchers co-authored a 2023 paper sponsored by the same institute on developing carbon-based battery materials. UCL noted that while CAGT appeared as a funder online, it was not listed in the formal acknowledgments section of the publication.

The government has instructed universities to end all collaborations with CGTRI and related organizations or face potential prosecution under the National Security Act, which carries a maximum sentence of 14 years in prison for aiding a foreign intelligence service. Security Minister Dan Jarvis emphasized the threat posed by covert Chinese intelligence activities within the academic sector. In a letter to university leaders, Jarvis stressed the importance of maintaining international partnerships while safeguarding national security through decisive action against foreign infiltration.

Opposition figures and security experts voiced support for MI5's position. Alicia Kearns, shadow security minister, criticized universities for unwittingly assisting Chinese intelligence, calling it a wake-up call for academics who downplay the political implications of cooperation with China. She also highlighted the impact of recent government decisions that limited universities’ powers to regulate campus activities. Meanwhile, Anthony Glees, a security expert at Buckingham University, described British universities as emerging national security risks, citing their financial pressures as factors that have made them vulnerable to exploitation by foreign intelligence operations.

Cambridge University declined to comment on the allegations. The situation highlights growing concerns within the UK over safeguarding academic research from exploitation by foreign state actors, particularly in strategically sensitive fields.
