I would much rather China control the entire digital landscape.
They are our friends and will only use it for good.
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.
