No need calculations, China will still win this. That, like our flights and accommodation

, is practically confirmed. Korea too are practically guaranteed at least a semis slot. After the disaster of their 2006 campaign, Korea will not want to make the same mistake.
What is not confirmed is how much fight other teams can give them. The most interesting battles are the jockeying of positions to occupy the other 2 semifinals slot. I count 6 other teams with almost equal strength. Japan and Malaysia, although seeded, are not guaranteed to win their groups, or even the quarterfinals even if they are group champions.
