It's not unique to China, but it's particularly prolific in China. One of the major reasons for the US tariffs against China was pressure for them to actually respect IP.

That is the official story. Obviously, though, it's really about kneecapping PRC's rapidly growing high-tech industries and "containing China's rise".

Until they get caught.

It won’t change if it’s not prosecuted.

In what court that protects IP and has jurisdiction in China would one file that lawsuit?

Good point and as expected, I have no idea. The question is if I have to file the lawsuit in China. My knowledge of law goes towards zero so I can’t even „armchair lawyer“ it. However, the question would be if it was possible to file the lawsuit in a country where TikTok has a headquarter.

It happens a lot more in China though
