There’s no doubt that China is on an aggressive technology acquisition track and has been for 20+ years. Way too much emphasis has been placed on the vacuuming of data from U.S. companies through targeted attacks (otherwise known by the marketing buzzword “APT”).
That’s actually a terribly inefficient way to conduct the scale of tech transfer that China needs and a lot of the data that gets scooped up has low value, which is partly why I believe that hacker groups from many different countries (including China) are the main instigators behind those attacks rather than the PLA or a Foreign Intelligence Service. Small scale hacker groups are like burglars breaking into peoples’ houses. They take as much as they can carry and then try to fence the goods for whatever they can get.
