Funny how both of these stole from Canada. I found no information whatsoever on whether Sinovac stole from anyone.
I did find information on Nortel and how Huawei took their secrets from Chinese hackers. But 1. Nortel filed bankruptcy the same year LTE was introduced, and the hacks were a few years before. I seriously doubt that their technology was this advanced to be retrofit for 5G that easily without much innovation. 2. These were still Chinese hackers. This industry also requires innovation.
