The CCP monitors everyone (including you and I), and we live in an interconnected world, this idea of 'they're not about to invade' is not really the point.
If China had it's way, they would not 'invade' Taiwan either, we would wake up one day and realize the process happened over 20 years and that Taiwan is under CCP control.
And that Vietnam, Singapore, Philippines, Japan, Korea are also subject to arbitrary power of the CCP a little bit like Lukashenko in Belarus is a stooge of Putin.

That's what the surveillance is for.
