US Imposes First AI Trade Secret Sanctions Following Google Engineer's Conviction for Theft

The US State Department announced sweeping sanctions on October 19 against five Chinese entities linked to Linwei Ding, a former Google engineer convicted of stealing the company's closely guarded artificial intelligence technology. Ding, 38, was found guilty in January 2026 on seven counts of economic espionage and seven counts of theft of trade secrets after uploading over 2,000 pages of confidential Google documents to a personal cloud account between May 2022 and April 2023. The stolen materials detailed specifications for Google's custom Tensor Processing Unit chips (TPU v4 and v6), graphics processing systems, and SmartNIC technology—the network interface hardware that powers Google's supercomputers and underpins its AI infrastructure.
