MI5 Links Z.ai Founders to Research Project With Ties to Chinese Spy Agency
UK security service flags four Z.ai founders for work on a project co-funded by a group linked to China’s main intelligence agency.

Key points
- Four Z.ai founders worked on a research project between 2018 and 2021.
- The project was co-funded by CGTRI, which MI5 links to China’s spy agency.
- Bloomberg reports these connections regarding the AI company’s leadership team.
UK intelligence agency MI5 has identified connections between four founders of Z.AI Co. and a research initiative with ties to Chinese state security. According to Bloomberg, the founders participated in a project co-funded by CGTRI, which MI5 describes as having very strong ties to China’s main spy agency.
The research project spanned from 2018 to 2021. Bloomberg reports that the four individuals, who are founders of one of China’s most promising artificial intelligence companies, worked on this specific initiative. The disclosure highlights the intersection of commercial AI development and state-backed research funding structures.
Context and Background
MI5 characterized the relationship between CGTRI and China’s primary intelligence apparatus as having very strong ties. This assessment comes from the UK’s domestic security service, which monitors foreign influence and espionage activities. The specific nature of the ties was not detailed in the Bloomberg report, but the association is central to the security concern.
The timeline of the research activity covers a three-year period ending in 2021. The involvement of Z.ai founders during this window suggests their professional activities overlapped with the CGTRI-funded work. Bloomberg identified the company as Z.AI Co., positioning it as a significant player in the Chinese AI sector.
Who Is Affected
The primary subjects of this report are the four founders of Z.AI Co. Their participation in the CGTRI-funded project links them to an entity with alleged espionage connections. Security professionals monitoring geopolitical risks in the AI supply chain may view this as a relevant data point.
Chinese artificial intelligence firms are increasingly under scrutiny for their funding sources and personnel backgrounds. The involvement of Z.ai founders in a project tied to state intelligence raises questions about data handling and intellectual property flows. No specific victims or compromised systems were named in the Bloomberg report.
What should you do?
Organizations sourcing AI technology from Chinese vendors should review their supply chain risk assessments. Security teams should monitor official statements from intelligence agencies regarding foreign entities. There is no immediate technical patch or software update available, as this is a geopolitical risk disclosure rather than a software vulnerability.
What to do and how to stay safe: Z.AI Co.
- Review vendor risk assessments for any AI tools sourced from Chinese companies like Z.AI Co.
- Monitor official communications from MI5 and other intelligence agencies for updates on foreign influence operations.
- Evaluate data sharing agreements with third-party AI providers to ensure compliance with national security guidelines.
- Stay informed about geopolitical developments affecting the AI supply chain through trusted news sources like Bloomberg.
