It’s in the article I referenced:

“Last December, a report from NGO Safeguard Defenders said it had identified 102 Chinese police stations operating in 53 countries, including five in Canada.”

To be fair, the article you posted claims that NGO is some kind of CIA backed organization. I don’t know if I really buy that, but I suppose it is possible. Antcedotally, I’ve heard other stories of China doing stuff like this (particularly when there were a lot of Hong Kong protests) but I’ll admit I don’t have much first hand evidence myself. It’s just, on a balance of probabilities, I’m much more likely to believe that an authoritarian regime like China is capable of doing it.

Also that example about the “Devil Eyes” dolls is bit disengenious to bring up. Your own source states that they only ever built a few prototypes. Granted, it does say an anonymous Chinese source says hundreds were shipped to Pakistan, but again I don’t think we can really trust China’s take on this.

The CIA has lots of looney plans (likely a product of Military-Industrial complex), but not many come to fruition becasue they are not practical.
