For the record, Google voluntarily withdrew from China as a form of moral protest (it didn't want to help the government censor/spy on its citizens). It wasn't just banned as a means of protecting local companies, since Bing isn't banned, nor for that matter is Azure or Outlook/Hotmail.
Google didn't withdrawn. They stopped censorshipping sensitive keywords and moved their servers to Hong Kong. Then China blocked their sites. You can't withdraw from the Internet by simply move your servers. Bing censor sensitive keywords so China allows them to stay.
