China’s Espionage War Against the US: How Beijing’s Stealing America’s Secrets and Why its Even More Dangerous Than the Soviet era KGB?

The controversy surrounding Nvidia CEO Jensen Huang and an alleged Chinese intelligence operation has reignited concerns in Washington over Beijing’s expanding espionage activities. From cyberattacks targeting American government agencies and telecommunications networks to alleged theft of military technology and corporate intellectual property, Chinese espionage has increasingly become a national security concern for the United States.

Nvidia has reportedly launched an internal investigation into whether Huang was targeted by a Chinese intelligence operative. The controversy involves Alice Huang, a Chinese businesswoman and executive associated with Singapore-based cloud computing company Megaspeed, who has reportedly been under US intelligence surveillance over suspected links to Beijing.

The allegations gained further attention after reports suggested that Alice Huang had developed a close relationship with the Nvidia chief executive. Huang separately acknowledged an extramarital affair in an internal communication to employees and apologised to his family and the company. However, the alleged intelligence operation and the nature of any connection between the businesswoman and Chinese intelligence remain under investigation.

The episode has brought renewed attention to China’s alleged use of unconventional intelligence-gathering methods, including cyber operations, corporate partnerships, financial incentives and human intelligence networks.

Unlike the Cold War-era espionage rivalry between Washington and Moscow, Beijing’s alleged intelligence operations increasingly exploit the interconnected nature of the global economy, American technological leadership and the openness of Western research institutions.

From Huawei to Nvidia: A Timeline of Chinese Espionage Allegations
2012: US Raises Security Concerns Over Huawei and ZTE

Chinese telecommunications companies Huawei and ZTE became major national security concerns in Washington in October 2012, when the US House Intelligence Committee released an investigation examining their potential links to the Chinese government.

The report warned that their telecommunications equipment could potentially provide Beijing with opportunities to access sensitive information or disrupt American communications infrastructure.

Both companies rejected the allegations. The investigation did not publicly establish that either company had used its equipment to conduct espionage, but it highlighted the potential risks associated with Chinese involvement in critical telecommunications infrastructure.

2013–2014: NSA Surveillance of Huawei

In March 2014, documents leaked by former National Security Agency contractor Edward Snowden revealed that American intelligence agencies had infiltrated Huawei’s computer systems.

According to reports by The New York Times and Der Spiegel, the NSA conducted an operation codenamed Shotgiant, targeting Huawei’s headquarters in Shenzhen.

The operation reportedly involved accessing company servers and monitoring communications involving senior executives, including founder Ren Zhengfei.

Washington was reportedly seeking evidence of Huawei’s alleged connections with the Chinese military while also attempting to understand the company’s technology and identify potential vulnerabilities in its telecommunications equipment.

The revelations demonstrated that Huawei had become a significant intelligence target for the United States as well.

2015–2016: Major US Government and Corporate Data Breaches

Chinese-linked cyber espionage allegations intensified following two major American data breaches in 2015.

In June 2015, the US Office of Personnel Management (OPM) disclosed that hackers had compromised its systems, exposing sensitive personal information belonging to millions of current and former federal employees.

The stolen information included background investigation records used for security clearance assessments, making the breach particularly concerning for American intelligence and national security agencies.

Another major incident involved American health insurer Anthem. In February 2015, the company revealed that hackers had accessed personal information belonging to approximately 78.8 million people.

US authorities subsequently attributed the attack to Chinese hackers, raising concerns about Beijing’s alleged efforts to collect large volumes of sensitive personal information.

2017–2019: Huawei Faces International Restrictions

The debate over Chinese telecommunications equipment intensified following the introduction of China’s National Intelligence Law in 2017.

The legislation requires Chinese organisations and citizens to support, assist and cooperate with national intelligence work. Critics in Western governments argued that the law could potentially allow Beijing to compel Chinese companies to assist intelligence operations.

In August 2018, Australia excluded Huawei and ZTE from supplying equipment for its 5G networks. New Zealand also imposed restrictions later that year.

In May 2019, the Trump administration placed Huawei on the US Commerce Department’s Entity List, restricting its access to American technology and components.

The United Kingdom initially permitted Huawei limited participation in non-sensitive parts of its 5G infrastructure in January 2020. However, following additional US sanctions and a reassessment of security risks, London reversed its position in July 2020, directing telecommunications operators to remove Huawei equipment from their 5G networks by the end of 2027.

2018: Cloud Hopper and Marriott Data Breaches

In 2018, the United States accused Chinese hacking group APT10 of conducting a prolonged cyber espionage campaign known as Cloud Hopper.

The operation targeted managed IT service providers, allowing hackers to potentially access sensitive information belonging to numerous businesses and organisations through compromised technology networks.

Reuters subsequently reported that hackers linked to China’s Ministry of State Security had breached eight major technology service providers.

The same year, Marriott International disclosed a separate breach involving its Starwood guest reservation database. The incident potentially exposed personal information belonging to approximately 500 million hotel guests.

The breaches highlighted how cyber espionage could exploit third-party service providers to gain access to large volumes of commercially valuable and personal information.

2023–2025: Volt Typhoon and Salt Typhoon Target American Infrastructure

Chinese-linked cyber operations became an even greater concern following the discovery of Volt Typhoon in May 2023.

US and allied intelligence agencies accused the hacking group of infiltrating critical infrastructure networks, including telecommunications, energy, transportation and water systems.

American officials warned that the operation appeared designed to establish persistent access to essential infrastructure, potentially allowing Beijing to disrupt civilian services during a future geopolitical or military confrontation.

In January 2024, the FBI announced that it had disrupted a network of compromised routers used by the hackers.

Another operation, Salt Typhoon, emerged in 2024 and reportedly targeted major American telecommunications companies, including AT&T and Verizon.

The hackers allegedly accessed call records, private communications and information associated with law enforcement surveillance systems.

By December 2024, the White House said at least nine US telecommunications companies had been affected.

In January 2025, Washington imposed sanctions on a Chinese hacking company and an individual over their alleged involvement in the campaign. Beijing rejected the accusations.

2026: Jensen Huang and the Alleged Chinese Intelligence Operation

The latest controversy involving Nvidia CEO Jensen Huang has brought the human intelligence dimension of Chinese espionage back into focus.

US authorities are reportedly examining whether Alice Huang, a Chinese businesswoman associated with Singapore-based Megaspeed, acted as an intelligence asset for Beijing.

According to media reports, Megaspeed had been under US surveillance since at least 2024 over allegations that it helped Chinese entities circumvent American export controls on advanced Nvidia AI chips.

The investigation has raised questions about whether corporate relationships and personal connections could potentially be exploited to obtain sensitive commercial or technological information.

Nvidia has reportedly initiated an internal investigation into the allegations. However, the claims concerning Alice Huang’s alleged intelligence links have not been independently established in a public judicial finding.
Chinese Espionage in the US: What the Numbers Reveal
The scale of the alleged espionage challenge extends far beyond individual controversies involving technology executives or telecommunications companies.

A 2023 study by the Washington-based Center for Strategic and International Studies (CSIS), titled Survey of Chinese Espionage in the United States Since 2000, documented 224 publicly reported instances of Chinese espionage targeting American interests.

The study found that nearly 69% of the documented cases occurred after Xi Jinping assumed China’s leadership in 2012–13.

It also identified the changing nature of Beijing’s intelligence priorities, with espionage increasingly directed towards achieving China’s long-term strategic, military and technological objectives.

According to the study, Chinese military or government personnel were directly involved in 49% of the incidents, while private Chinese citizens accounted for 41%. The remaining 10% involved foreign nationals, including Americans allegedly recruited by Chinese officials.

These figures point towards an intelligence ecosystem that extends beyond conventional government agencies and incorporates private individuals, businesses and technology networks.

The economic consequences are equally significant. The Commission on the Theft of American Intellectual Property estimated that intellectual property theft costs the US economy up to $600 billion annually, with China identified as a major source of the problem.

The CSIS research also documented multiple alleged methods of acquiring sensitive information, including cyberattacks, financial incentives, recruitment of researchers, corporate partnerships, smuggling of export-controlled technology and human intelligence operations.

Why Chinese Espionage Poses a Bigger Challenge Than Soviet Spying

The fundamental difference between Chinese and Soviet espionage lies in the economic and technological environment in which their intelligence operations operate.

During the Cold War, the United States and the Soviet Union functioned largely within separate economic and political blocs. Limited commercial integration made it relatively easier for Washington to restrict Moscow’s access to sensitive Western technologies.

China, however, occupies a fundamentally different position.

Its economy is deeply integrated into global trade, manufacturing, technology development and supply chains. US-China bilateral trade alone is worth hundreds of billions of dollars annually, while both countries remain among the world’s largest trading economies.

China also occupies a central position in critical mineral processing, particularly rare earths, which are essential for manufacturing electric vehicles, advanced electronics, missiles, fighter aircraft and semiconductor-related technologies.

Its universities, research institutions, technology companies and millions of students and professionals participate in global knowledge networks.

This interconnectedness creates opportunities for legitimate technological cooperation but also presents potential vulnerabilities that intelligence agencies can exploit.

Consequently, Washington cannot simply isolate China from the American technological ecosystem in the same way it restricted Soviet access to Western technology during the Cold War.

The challenge is further complicated by the emergence of artificial intelligence, advanced semiconductors, cloud computing and other dual-use technologies that have both commercial and military applications.

China’s alleged espionage activities therefore extend beyond traditional intelligence collection. They increasingly intersect with economic competition, technological development and national security.

The Jensen Huang controversy, regardless of how the ongoing investigation ultimately unfolds, highlights the growing complexity of this challenge.

For Washington, the bigger question is no longer simply how to identify foreign intelligence agents operating inside the United States. It is how to protect its technological advantages in an interconnected world where sensitive information can potentially be accessed through commercial relationships, digital infrastructure, research collaborations and human networks.

The Cold War offered relatively visible intelligence battle lines. The contemporary US-China rivalry does not. Beijing’s alleged espionage operations exploit the very openness and global integration that underpin American technological and economic leadership.
