Survey of Chinese-linked Espionage in the United States Since 2000

This survey lists 137 publicly reported instances of Chinese espionage directed at the United States since 2000. It does not include espionage against other countries, U.S. firms or persons located in China, nor an additional 50 cases involving attempts to smuggle munitions or controlled technologies from the U.S. to China. We also did not include more than 1200 cases of intellectual property litigation brought by U.S. companies against Chinese entities in either the U.S. or Chinese legal systems.

For those cases where we could identify actor and intent, we found:

  • 57% of actors were Chinese military or government employees.
  • 36% were private Chinese citizens.
  • 7% were non-Chinese actors (usually U.S. persons).
  • 36% of incidents sought to acquire military technology.
  • 46% of incidents sought to acquire commercial technologies.
  • 18% of incidents sought to acquire information on U.S. civilian agencies or politicians.

These reported incidents are derived from open source material. The sources are footnoted. The list may not reflect the full number of incidents and may not be complete. Of the 137 incidents, the decadal breakdown is:

  • 2000-2009: 27%
  • 2010-2019: 73%

This could reflect an increase in the number of incidents after 2009, but it may also reflect variances in the public reporting of espionage cases, as greater attention was paid to the problem and the U.S. government reportedly became less resultant to publicly identify China as the perpetrator after 2007.
