The United States has imposed sanctions on five Chinese companies and investment entities linked to the theft of Google's artificial intelligence trade secrets, in a significant escalation of Washington's response to technology espionage originating from the Linwei Ding case. The State Department announced the designations on October 19 under the Protecting American Intellectual Property Act (PAIPA), a federal law that authorizes penalties against foreign individuals and organizations involved in significant theft of American trade secrets. The action was reported by the South China Morning Post, UPI, The Information and other outlets, and the department's statement was titled "Imposing Sanctions to Protect Americans from Intellectual Property Theft."
Who Is Linwei Ding? For more context on this story, see our ongoing latest AI developments.
Linwei Ding, a Chinese national and former Google software engineer, was convicted by a US federal jury in January on seven counts of trade secret theft. His arrest in early 2024 became one of the most closely watched AI trade-secret prosecutions in the United States. According to the State Department, Ding stole thousands of pages of confidential Google information relating to advanced AI technology, acting for his own benefit and for the benefit of Chinese technology companies.
The criminal conviction, however, is only part of the story the sanctions address. In 2023, Ding founded Shanghai Zhisuan Technology Co Ltd, a startup that promoted its capability to develop software for accelerating machine-learning workloads. According to the State Department's account as reported in press coverage, Ding applied to Beijing-based startup incubator and venture firm MiraclePlus while claiming experience with Google's internal technology and systems. MiraclePlus went on to provide seed funding to Zhisuan.
The Five Entities on the List
The designations target the company Ding founded and the financial network that backed it. The five sanctioned entities are:
- Shanghai Zhisuan Technology Co Ltd
- Qiji Chuangtan Beijing Investment Management Co Ltd
- Beijing Qiji Chuangtan Phase I Venture Capital Center Limited Partnership
- Beijing Qiji Chuangtan Phase II Venture Capital Center Limited Partnership
- Beijing Qiji Chuangtan Zhiyuan Enterprise Management Center Limited Partnership
The Qiji Chuangtan entities are the investment vehicles associated with MiraclePlus, the incubator that seeded Zhisuan. By designating the funds alongside the operating company, Washington is signalling that financing intellectual-property theft carries economic consequences of its own — a deliberate widening of the aperture beyond the individual who committed the theft.
A Separate Track From the Criminal Case
The State Department stressed that the sanctions are a distinct action from Ding's criminal prosecution. Where the criminal case punished the individual, the PAIPA designations aim at the broader ecosystem that allegedly converted stolen technology into a funded venture.
The move was backed by an investigation involving the Justice Department and the FBI, according to reporting on the announcement. It marks a new front in the US-China technology conflict: not export controls or chip restrictions, but the financial isolation of companies and investors deemed to have profited from stolen American AI research.
PAIPA gives the US government a civil-economic instrument that operates independently of criminal proceedings. Designation under the act exposes foreign companies and their principals to measures that can include restrictions on dealings with US persons and institutions, effectively cutting designated entities off from parts of the American financial system.
The economics explain why the financial network is in Washington's crosshairs. Software for accelerating machine-learning workloads is among the most valuable intellectual property a frontier lab owns: it determines how efficiently expensive chips and data centers convert capital into trained models. A startup founded on misappropriated versions of that technology, seeded by reputable investors, can raise further capital, hire aggressively, and legitimize the underlying asset — problems a criminal verdict against one engineer cannot undo. Sanctioning the vehicles that funded the venture is designed to choke off that path.
Context: A Broadening Crackdown on Chinese AI
The sanctions land amid a month of escalating US measures targeting Chinese AI. Last week, the Department of Homeland Security issued an order banning DeepSeek from federal civilian agency IT systems, citing supply-chain and data-security concerns. Together with the PAIPA designations, the measures show Washington tightening both the security and the economic screws on Chinese AI firms operating with American technology.
What Comes Next
The State Department framed the designations as deterrence: a message to foreign companies and investors that profiting from American innovation obtained through theft will carry lasting costs. Chinese authorities have consistently rejected US allegations of state-backed technology theft, and Beijing has retaliated in past disputes with its own measures against American firms.
What remains to be seen is whether PAIPA becomes a routine tool in AI espionage cases. Its application to a marquee AI trade-secret case underscores the US government's intent to pursue the money behind the theft, not only the thieves.
