From Wikileaks, via Spiegel Online: "No matter whether it's war in Darfur, repression in Zimbabwe or corruption in Nigeria -- for the Chinese, it's not their problem. For example, instead of taking Zimbabwean dictator Robert Mugabe to task for his totalitarian policies and looting of his own country, they bestowed an honorary doctorate on him in 2005 and declared him 'China's No. 1 Friend.' Three years later, in 2008, they sent Mugabe the An Yue Jiang, a ship full of weapons and ammunition."
The Chinese government is at least internally consistent in their position on basic civil liberties: Memetjan Abdulla was just sentenced to life in prison for his role in the 2009 Uighur riots in Xinjiang. And what was his role, exactly? Reporting on the riots.
