MI5 Says China-Linked Group Approached 100+ UK Academics

Britain's domestic intelligence agency, MI5, told UK academics on Wednesday to stop working with the China General Technology Research Institute (CGTRI), saying the group's "primary purpose" is to fund academic research that strengthens the espionage capability of China's Ministry of State Security (MSS), according to Al Jazeera.

How many academics did MI5 say were targeted?

MI5 counted more than 100 UK-based academics approached by the CGTRI, concentrated in artificial intelligence, cybersecurity, covert communications systems and steganography, per the same report. MI5 said it believes many of those academics and their institutions engaged with the CGTRI in good faith, without knowledge of the group's ties to the MSS.

What legal risk do academics now face?

Academics who continue taking CGTRI grants or collaborating with the group risk prosecution under the UK's National Security Act, a law enacted in 2023 that expanded government authority to target foreign espionage and hostile state activity, MI5 said. The agency framed the warning as a rare public alert rather than a private notice to universities, a step it has taken only a handful of times in recent years.

"This activity supports MSS espionage, which poses a threat to UK national security," MI5 said in its Wednesday statement, as quoted by Al Jazeera.

How has the UK government responded?

Security Minister Dan Jarvis said he wrote to all university leaders in Britain directing staff to end any relationship with the CGTRI. "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, according to Al Jazeera. He added that "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."

Beijing had not issued an immediate response as of the report's publication. China has previously denied similar espionage accusations from UK authorities, Al Jazeera noted.

What is the timeline of UK warnings about Chinese academic espionage?

• 2023: Parliament passes the National Security Act, giving UK authorities expanded power to prosecute foreign espionage and hostile state activity.
• 2025 (last year): MI5 Director-General Ken McCallum said Chinese intelligence operatives were using fake job advertisements to try to extract data from British professionals; MI5 separately issued an alert to UK lawmakers in November.
• Sept. 30, 2026: MI5 issues a public alert naming the CGTRI and instructing academics to sever ties, citing risk of prosecution under the 2023 Act.

How does this fit the broader UK-China relationship?

China is the UK's third-largest trading partner, and London has pursued closer trade ties even as it has issued repeated espionage warnings, Al Jazeera reported. Earlier this year the UK approved plans for China to build its largest embassy in Europe in London, a decision a UK court ruled lawful, according to related Al Jazeera coverage cited in the report. The dual track — courting Chinese investment while flagging intelligence threats — has defined the relationship in recent years, per the same reporting.

• 100+ — UK-based academics MI5 says the CGTRI approached, spanning AI, cybersecurity, covert communications and steganography research (MI5 alert, Sept. 30, 2026, via Al Jazeera).
• 2023 — Year the National Security Act took effect, the law under which continued CGTRI engagement could trigger prosecution (Al Jazeera, Sept. 30, 2026).

Glossary

• MSS (Ministry of State Security): China's primary civilian intelligence agency, which MI5 says benefits from CGTRI-funded research.
• CGTRI (China General Technology Research Institute): The Chinese organization MI5 says funds UK academic work with the stated aim of aiding MSS espionage.
• National Security Act (2023): UK legislation that broadened prosecutorial powers against foreign espionage and hostile state activity.
• Steganography: The practice of concealing information within other, non-secret data — one of the research areas MI5 says the CGTRI targeted.

MI5's alert does not name specific universities or individual academics, and Al Jazeera's report does not include a breakdown of the 100-plus academics by institution or discipline beyond the four fields listed.
