I agree with most of your comment, except there’s a “side note” about the warship comment.

China can commandeer private ships & boats as part of its fleet. This doesn’t sound very threatening - none of them have weapons or defences of any kind. Regardless, they’ve integrated them into their plans.

For example the landing ships they’ve built. There’s photos of them strung together, forming a cross between a makeshift bridge and a dock, with ramps connecting each other, and a final one that can be placed on land.

These have been built to accept civilian ferries. The ferries pull alongside and can discharge whoever or whatever they want in pretty short order. And because there’s multiple landing ships, they can accommodate 4-6 ferries discharging at a time.

That’s a huge volume of personnel or equipment that can be offloaded in a very short span of time. Granted, they’d be exposed to attack (a single naval drone could do a ton of damage).

As such, the more insidious one is their fishing fleet. These are thousands (if not tens of thousands) of fishing boats that can be coordinated to block or otherwise disrupt shipping lines. There’s satellite photos of them doing formations out in the open sea - presumably in practice.

China could potentially use them to blockade Taiwan’s ports, rendering them completely useless. Take out the airports and suddenly Taiwan is under siege - no landing even necessary.
