GOOG may pull out of China but they were never making much money in China to begin with, all they've gotten is bad press in the west and a ton of hassle from the Chinese government.
The Chinese want their own companies running every major aspect of the their internet, they're passing laws constantly to restrict access to international companies such as Activision/Blizzard who can no longer run World of Warcraft in China.
If you want to make money from Chinas economic boom then buy Baidu. As for Google, leaving China may hurt in the short term but not much, they're also sure to put pressure on the US government to ensure others like MS, Yahoo and Co. don't try take their place by waving that 'Do no evil' flag that they forgot about.
I've been mulling a GOOG purchase for a while, I'm thinking I'll see where the stock ends up in a couple of days, GOOG is already down 5% since the new year, this could knock another 5% off as people panic sell and make it a bargain.
