America backs China, this will all change at the next Kyoto Extravaganza which will take place after Bush leaves office. This will probably mean American finally gets on board and China is the odd man out..finally.
I think the big problem is places like Wal-Mart have made America so dependant on Chinese imported goods that it will be hard to take a firm stand. Then again no one in China can afford the products they make so I spose limiting trade would hurt them as much as it hurts us.
