Nvidia's Jensen Huang scandal brings China's spy networks into view

It sounds like the opening of a spy thriller. Nvidia's CEO Jensen Huang has admitted to being unfaithful, with reports he had three extramarital affairs.

One is said to have been with Alice Huang (no relation), a former executive at Singapore-based Megaspeed International, who was reportedly suspected of working for Beijing.

The US Justice Department is investigating whether Megaspeed violated export control laws by facilitating Chinese access to restricted AI chips.

It has not been established yet what exactly Ms Huang provided to China's intelligence network. However, it has already rattled investors and brought wider scrutiny to Nvidia's business with China.

The tech giant's stock hit a 14-year low relative to earnings this week, while facing a proposed shareholder class-action lawsuit alleging it misled investors over Mr Huang's relationship with Alice Huang.

The crisis also led to Mr Huang's resignation as Nvidia chief executive and director, ending his 33-year leadership of the company.

When romantic relationships become intertwined with national security, private lives are inevitably drawn into geopolitical rivalry.

During the Cold War, the East German intelligence service ran so-called "Operation Romeo", in which male agents were instructed to develop romantic relationships with women in the West German government to gain access to classified information.

Today, intelligence activities may also leverage commercial networks and professional channels, making it increasingly difficult to distinguish legitimate connections from potential espionage activity.

China's spy network may help Beijing gather information, but over-relying on it can also erode the relationship China needs with the West.

The cost may be that the people and relationships connecting China and the West are pushed aside, leaving both sides with fewer ways to understand each other amid an intensifying China-US competition.

To understand why, we need to look at how China's intelligence system operates.

A complex network

According to The New York Times, US intelligence concluded that Ms Huang had been recruited by China's Ministry of State Security (MSS) to gather information on Mr Huang and Nvidia, and potentially to influence the company's position on selling advanced AI chips to China.

The MSS is China's principal civilian intelligence and counterintelligence agency. It gathers human intelligence through covert operations and contacts, cultivating relationships in government, business, academia and Chinese communities overseas.

There is no publicly available figure for the size of the MSS's overseas network.

The Parliament of the United Kingdom's Intelligence and Security Committee found that people cultivated as contacts by the MSS may not necessarily be aware they are dealing with intelligence officers.

Beijing's intelligence system is not just one network. It also has the People's Liberation Army (PLA), which gathers military intelligence and the Ministry of Public Security (MPS), which is responsible for policing and domestic security.

These branches can also work through private technology companies and contractors, where their activity is not automatically attributed to one agency.

US court documents allege that the MSS and MPS have used Chinese hacking groups to collect information and obscure the government's role in the actions.

In one case, the US Justice Department said a Chinese contractor stole data by hacking emails, phones and servers linked to government agencies and dissident groups. It sold or attempted to sell the data to at least 43 MSS or MPS bureaus across 31 provinces and cities.

This shows how an intelligence system can draw on private firms, though it doesn't mean that all Chinese technology companies or contractors are part of a spy network.

The MPS also has Network Security Police Offices in major Chinese internet companies and digital platforms. They can gather online intelligence from user data to support investigations into cybercrime and national-security threats.

More than 1,000 offices are embedded in at least 10 major technology firms, including Tencent, Baidu, Sina and Alibaba.

Similarly, these offices are established in the country's major telecoms, such as China Mobile and China Telecom, monitoring unlawful activities and investigating cases that could be linked to national security.

These overlapping structures between multiple state departments, companies and professional networks can make it difficult for people working between China and the West to know when an ordinary contact may carry national security risks.

The white gloves

Public reporting does not establish exactly when Ms Huang was recruited, what she knowingly did, or what information she passed on.

She may have had direct contact with the MSS, or may have acted as an intermediary for people linked to it. Neither possibility has been substantiated publicly.

There has also been scrutiny over whether Ms Huang was the ultimate owner of the assets and businesses associated with her name.

She reportedly worked as a journalist before moving into private banking and investment, and later became involved in corporate acquisitions and cross-border transactions.

She was involved in a project to build the Shanghai AI Computing Centre, and continued to oversee Megaspeed's daily operations after its shares were transferred through companies in the British Virgin Islands and Singapore, according to the New York Times.

These details point to her role as a cross-border intermediary, with financial expertise and connections to investors, companies and clients acting behind the scenes.

The term "white glove" is used for an intermediary who holds or manages assets on behalf of another party. It is a common approach used by Chinese offshore companies to separate the registered shareholders, the actual controllers and the ultimate beneficial owners.

In some documented cases, offshore businesses have been linked to relatives or associates of China's political elites.

Public information has not established who ultimately controls Megaspeed, or who uses the advanced Nvidia AI chips.

However, the allegations involving Ms Huang, along with her romantic relationship with Mr Huang, have amplified the open secret in these opaque business networks.

Western businesses have long been attracted to commercial incentives and the access to the lucrative Chinese market, often accepting complex ownership structures to avoid political involvement.

Now, they are reassessing how to manage risks, particularly those related to ownership transparency, and ensuring that they remain resilient to political factors such as the downfall of senior Chinese officials or Western sanctions.

Chilling effect

It's not just "white gloves" who have worked between Chinese investors and American clients.

China's United Front Work Department (UFWD) is actively building relationships with overseas Chinese communities and influential figures to promote Beijing's interests.

But the line can become blurred when the groups and individuals are used to advance political agendas, leaving some worried that their associations or public views could attract unwanted suspicion.

As national security concerns have expanded from traditional military, diplomatic and intelligence spheres to include technology, data and rare earth, more people working across China and the West — in sectors that once involved routine professional and personal interactions — are also feeling the pressure.

Cooperation in the fields of scientific research, academia, AI and critical minerals — once relatively unrestricted — is increasingly being constrained by national security concerns.

The allegations surrounding Alice Huang and Jensen Huang have made these concerns more tangible.

Westerners in China collaborating with Chinese partners, as well as mainland Chinese people working overseas, may worry that legitimate and lawful exchange of information or commercial connections could be perceived as a risk without their knowledge.

This also hinders engagement between China and the West, and may make it harder for both sides to understand each other as strategic competition deepens.

In the field of China studies, the West relies on people with first-hand experience of China to understand the country's complexities and prevent misunderstanding. China, in turn, benefits from foreign scholars and journalists living in the country to explain its society and politics to the outside world, and to foster the exchange of knowledge across borders.

But under growing pressure from national security concerns, these channels may narrow further.

The US investigation into Megaspeed, as well as the scrutiny of Ms Huang, will likely add to tension between the two nations.

Beijing has denied the allegations of espionage, while extending the export-control waivers on some of its rare-earth minerals — which are crucial for producing AI chips — until January.

With US President Donald Trump expected to attend the APEC leaders' meeting in Shenzhen next week, it remains unclear how the case will affect bilateral discussions.

Whatever the outcome of the case, its effects on trust may deepen and prove difficult to reverse.
