This was Björk, in Shanghai, shouting "Tibet, Tibet" in front of thousands of Chinese fans.
Newspapers write that she upset Chinese fans, that people fled the area, shocked by what she said. They should know better than always following those who are in power. Look at the video: people are singing with her, and writing that they did not understand her words - simply the word "TIBET" shouted three times at the end of Declare Independence is ridiculous.
Of course, only those who wanted to criticize her act were allowed to express their opinion in China. China is not the land of free speech. Think of Hu Jia, and many others.
