Google's "Don't Be Evil" image got a boost in 2010 when the company picked a fight with the Chinese government over the regime's censorship policy. Even Google, though, can't afford to make long-term enemies with the leaders of the world's second-largest economy. Case in point: Google needs to secure antitrust approval from various regulators around the world for its proposed $12.5 billion purchase of Motorola Mobility, the company announced in Aug 2011. The US, the European Union, and Korea have all given their blessing. Just guess which country still hasn't. China's Commerce Ministry is the only regulator still looking into the deal. Having made no friends in Beijing after its high-profile fight against Chinese censorship, the company has reason to be worried. Still, there are limits to what China can do against Google.
