Do you know what 'passive' means? It's a basically a mirror for a specific frequency. There's no way to "detect" it other than tearing apart whatever it's hidden in.
The fact that it was made with 1960's Soviet analog tech should tell you that China could plausibly make something better and smaller now.
It would certainly be detectable. You could do an X-ray, sweep the RF spectrum and see the energy disappear at the right frequency, things like that.
They had that tech in the 60s too.
Also when the bug was in operation it was definitely not passive. It was being fed by what must have been a really strong signal to power it, and transmitted the results back.
