Sinovac, "their" covid vaccine, was stolen from Canada when Canada offered to help them produce a vaccine. Signed an official treaty and everything. Canada did the hard work that they literally couldn't, and still can't, do. Then they took the vaccine and claimed it was entirely their own work.
Huawei's 5G development miracle is 100% stolen technology from Nortel. They did no work of their own other than work so shoddy even the UK Tories didn't want to touch it.
These are just the two highest profile ones that go right to the leaders of the CCP.
