Does China REALLY care about factories or any other buildings?
They can put up a factory in a week.
They want that Land and those people under their control. And have since the split. Long before there were any factories.
China plays the long game.
If China had to raze the whole island and kill every single person. They would still do it and just start from 0 and repopulate with mainlanders.
Advanced semiconductor factories are no trivial thing to “put up” with many trade secrets are involved.
Even the Taiwanese cannot fully operate them without American consultation and our engineers constantly flying out there.
In the case of semiconductors, the plant is important..along with the knowledge.
The semiconductors made in that plant are evidently a lot better than those made in China.
So, if China was invading for the chips the plant would be important. I think the chips would be a partial reason.
I think the strategic location of the Island is more important. If China doesn’t hold it, it could be a base right off their mainland for Chinese enemies.
If China held the island, it would be able to project power outward over the sea lanes in, out, and around China.
None of this bodes well for people trying to build a life on the island.
