Invading Taiwan cuts out this one big trading partner and source of capital and gives the chicoms nothing in return
They will just wait -- remember the Chinese think in terms of centuries. They think that US power is going to wane further. As time passes and the chicoms become more a capitalist oligarchy (which arguably they already are), there will be less separating the two chinas and then they will plan to reunite peacefully.
Taiwan's only purpose is for China to sabre-rattle every now and then
In more concrete terms China is interested in siberia and central asia for energy.
Any thoughts on #104?
