My bet is CCP sell Taiwan at huge discount.
My point on this hypothesis is that everything in China is around single point: that is, CCP power. They do everything to keep it. Using this logic, you can explain a lot of things clearly. You must understand absolute nothing concerns CCP other than their power.
To attack Taiwan or not, it comes to CCP power in China. They have been concerned by something integrity of terroitery or anything else.
