I think the biggest problem with hardware implants is that you loose plausible deniability with it. For a state actor that seems a big risk. Especially China would have to lose big time as no one would trust their electronics any longer. You can have almost the same gain with a software implant. It's easier to pull off and you get plausible deniability as a bonus.
