I've come to the opposite conclusion that China won't invade the Republic of China because China has won this fight already. Unless they really, really have to because the Republic of China has declared independence from China. They have stated this many, many times already. Cast your mind back 150 years or so. The Union only declared war and invaded the Confederacy because of the same reason. No side wins in a Civil War. Incidentally, the Chinese Civil War is a frozen conflict, but still ongoing even though a Truce is in effect. It's almost exactly the same thing as the ongoing Korean War that's never been concluded after 70-odd years.
