China will ban all entertainers from overseas, Hong Kong and Taiwan who have ever attended activities that "threaten national sovereignty", the government said on Thursday, after an outburst by Icelandic singer Bjork.
Earlier this year, Bjork shouted "Tibet! Tibet!" at a Shanghai concert having performed her song "Declare Independence", which she has used in the past to promote independence movements in other places such as Kosovo.
China has ruled Tibet with an iron hand since its troops marched into the Himalayan region in 1950, and swiftly condemns any challenge to its authority there.
"Any artistic group or individual who have ever engaged in activities which threaten our national sovereignty will not be allowed in," the Ministry of Culture said in a statement on its website ( www.ccnt.com.cn ).
