THe Chinese like the satellite state [North Korea] between China and our forces, they fear that in a reunified Korea, American troops would be at the Yalu River and they've seen that movie before. They didn't like it the first time they saw it and they don't like it any better today. So they are quite happy with the divided Korean peninsula and that's a fundamental difference between the way they see things and the way we see things.
