China will tighten its controls over foreign singers and other performers after Icelandic singer Bjork shouted "Tibet! Tibet!" at a Shanghai concert last weekend, the Ministry of Culture said on Friday.
Bjork chanted the name of the Chinese-ruled Himalayan region after performing her song "Declare Independence", which she has used in the past to promote independence movements in other places such as Kosovo.
The performance "not only broke Chinese laws and regulations and hurt the feelings of Chinese people, but also went against the professional code of an artist," the ministry said in a statement quoted by the official Xinhua news agency.
