Isn't this nice of China? The Chinese government has taken it upon itself to to "purify the Internet's cultural environment and protect the healthy development of minors." Funny how it's always to protect children, no matter where it happens. This means demanding the Google remove whatever they consider objectionable. This means 2 things: pornography (to protect children), and websites critical of the Chinese government, like the one you're visiting at the moment (to protect - who?).
It's no surprise when the world's biggest country walks all over freedom of information and expression. What's even scarier is when supposedly free countries like Australia start imitating them. If the rest of the world keeps allowing China to pressure media and internet companies, maybe we won't have to wait for own governments to start censoring news.
