Have you ever used Baidu? It's worse than Google even when searching for Chinese. Baidu did a few things well: it was good for finding pirated content and porn, but for actual research, it's horrible.
I don't think OP was saying Google would lose to Baidu because of quality, but because the Chinese government has deep fingers in Baidu there's a very good chance they will cripple Google's services in favor of Baidu's.
