Soooo China is building sophisticated, highly specialized barges for establishing a beachhead without a harbor and moving heavy machinery across. These would be pretty helpful in a sustained campaign against Taiwan.
These ships happen to be able to connect to the many Chinese "civilian" roll on-roll off (roro) ferries that are built to military spec and can handle Chinese tanks.
These "civilian" roros happen to participate in military exercises.
Considering this all took place well before the arms deal, that's probably a good reason why China can be considered the aggressor. Maybe the $11.1 billion in arms deals is in response to that?
There's also xi jinping saying that the unification of Taiwan and China is "unstoppable" in a speech today, right after these military exercises.
TSMC was developed by a Taiwanese citizen to be a "silicon shield" - it's too valuable for other countries to risk a war.
It's why trump was trying to cajole TSMC to move 50% production to the US and they were like "nah"
