China Accuses Foreign Spies of Stealing Secrets in 5 Tech Sectors

China’s top intelligence agency has publicly accused foreign spies of stealing secrets from at least five strategic domestic industries, a significant escalation in the technology conflict with the U.S. The Ministry of State Security (MSS) claimed on social media that its investigations revealed widespread espionage targeting the nation’s rare earth, photovoltaic, semiconductor, high-end chip, and artificial intelligence sectors.

In a direct counter-narrative, U.S. officials and private sector experts argue the announcement is a deflection from Beijing’s own long-standing campaign of economic espionage. "China steals upwards of $600 billion annually from U.S. companies," Tom Lyons, a former CIA officer and co-founder of the 2430 Group, said in a recent interview. He noted that the actual figure is likely much higher, as most corporate victims do not report the theft due to reputational concerns.

The U.S. Department of Justice has pursued multiple cases illustrating the scale of the issue. One recent high-profile case involved Linwei Ding, a former Google engineer convicted of stealing proprietary AI chip architecture for a Chinese company. Having stolen the technology, Chinese firms can often produce copycat products at a fraction of the cost, aiming to capture market share from the original innovators.

This dynamic is part of a broader strategy by Beijing to not just steal intellectual property from individual firms, but to dominate and displace entire industries. According to U.S. intelligence assessments, China’s systematic theft over the past 25 years has been instrumental in eroding or eliminating critical U.S. sectors, including steel, telecommunications, and solar manufacturing. The current tensions highlight the immense economic stakes as the rivalry extends into next-generation technologies.

A Pervasive Threat

U.S. law enforcement officials describe the threat of Chinese espionage as deeply embedded and widespread. Tracy Walder, a former FBI agent, told NewsNation that while the agency once had only two offices examining Chinese espionage, there are now open cases in every FBI field office across the country. The Office of the Director of National Intelligence’s 2023 threat assessment listed China as a top threat, with a primary focus on targeting America’s critical infrastructure.

The infiltration extends into the political sphere, with U.S. officials alleging that Beijing attempts to influence policy at the local level. The recent case of Eileen Wang, the mayor of Arcadia, California, who pleaded guilty to acting as an illegal agent for China, highlights these concerns. According to her plea agreement, Wang worked to promote pro-PRC and anti-Taiwan stances. Rep. Raja Krishnamoorthi, a member of the House Select Committee on China, stated that he and other members of Congress have been personally targeted by Chinese influence operations.

Market Impact and Supply Chain Risks

The MSS announcement introduces a new layer of uncertainty for global technology markets and the intricate supply chains that support them. The public accusations could pave the way for retaliatory actions from Beijing, potentially including further trade restrictions, sanctions on foreign firms, or disruptions to the supply of critical materials like rare earths, which China dominates.

For investors, this escalates the geopolitical risk associated with companies that have significant manufacturing or sales exposure to China. The targeted sectors—semiconductors, AI, and photovoltaics—are at the heart of the global tech economy. Increased tensions could lead to higher compliance costs, supply chain reorganization, and heightened market volatility. Conversely, the announcement may signal increased government support and protection for domestic Chinese companies in these sectors, potentially leading to a rally in their stock prices as capital is redirected inward.
