Investigations ranging from the recruitment of American students to claims linked to Nvidia CEO Jensen Huang are increasingly pointing to China’s Ministry of State Security (MSS). The MSS, an opaque agency without a public-facing website beyond a whistleblower portal, has become a focal point as Beijing intensifies its national‑security posture since 2023.

The MSS supervises a network of provincial and national bureaus that collect intelligence and coordinate covert operations. While not Beijing’s sole intelligence outfit, the ministry repeatedly surfaces in high‑profile cases. In recent years, the U.S. Treasury has sanctioned Chinese individuals and entities it alleges are tied to the MSS, following hacking attempts targeting American firms.

U.S. intelligence officials believe the MSS recruited businesswoman Alice Huang to gather information on Nvidia CEO Jensen Huang, according to reports this month by the Financial Times and The New York Times. Alice Huang is unrelated to Jensen Huang, who publicly acknowledged an extramarital affair over the weekend. It remains uncertain whether any sensitive data was exchanged.

Earlier this year the MSS approached a person familiar with Alice Huang to learn more about her business ties and contacts, The FT reported on Wednesday, citing the individual who was questioned. The inquiry appears unconnected to any alleged wrongdoing, and it followed a Singapore probe into the company regarding alleged chip‑smuggling activities.

Growing prominence

China established the Ministry of State Security in 1983 partly to counter risks arising from its opening to foreigners after decades of isolation, according to research by Sheena Chestnut Greitens, an associate professor at the University of Texas‑Austin.

Under President Xi Jinping, the MSS has gained increased political clout, aiming to “strengthen China’s protections against espionage and foreign infiltration,” Greitens wrote in a recent issue of China Leadership Monitor, a publication linked to the German Marshall Fund.

In 2023 the MSS launched a WeChat account to enhance public awareness of security matters. A recent post criticized an unidentified individual with a Chinese surname for falsely reporting a colleague as a spy to a foreign organization after the colleague secured an overseas assignment the individual coveted.

The MSS operates independently of China’s Cyberspace Administration and the Ministry of Public Security, whose minister, Wang Xiaohong, has met with former U.S. Secretary of State Antony Blinken. However, the agencies sometimes collaborate.

In September, MSS Minister Chen Yixin published a rare article in the Cyberspace Administration’s journal on the need for better AI governance and risk prevention, coinciding with warnings from leading U.S. AI executives about uncontrolled technological development. Chen has also met with Vietnamese and Lao counterparts in Beijing this year, according to official Chinese statements.

Focus on technology

Beijing’s tech drive increasingly targets the U.S. sector to close the artificial‑intelligence gap, according to Matt Pearl of the Center for Strategic and International Studies, speaking to CNBC.

A Stanford University newspaper reported last year that an MSS agent allegedly posed as a student for years to harvest sensitive information, citing anonymous Stanford experts who said the MSS uses civilians to “quietly extract the know‑how behind American innovation.”

Other cases underscore this trend, even when not directly tied to the MSS. CrowdStrike disclosed in June that Chinese entities accounted for more than half of state‑sponsored intrusions targeting tech firms—especially AI assets—over the 12 months through March 31.

Brian Abbott, founder and CEO of the U.S. start‑up Agentiq Capital, told CNBC he believed a former Chinese employee deliberately altered code and website content to sabotage the company’s venture‑capital prospects. The individual was dismissed earlier this year, and Agentiq filed a complaint with the FBI. CNBC could not independently verify the claim or its connection to the MSS.

In a separate incident, U.S. investigators suspect a former senior Federal Reserve official leaked central‑bank information to a Chinese government operative.
