Following Bjork’s ‘outburst’ at her concert in China earlier this year, the Chinese government has announced that it will impose severe restriction on foreign performers. In a statement posted on its website today (July 17), the Chinese government said, “Any artistic group or individual who have ever engaged in activities which threaten our national sovereignty will not be allowed in.” That’s not all, Reuters reports that the government will also ban entertainers who, while performing in the country, “threaten national unity,” “whip up ethnic hatred,” “violate religious policy or cultural norms” or “advocate obscenity or feudalism and superstition.” The government also said it must pre-approve the content of encore performances.

All this comes after Bjork’s recent performance in Beijing where she made a vocal show of support for freedom in Tibet, which has been oppressed by the Chinese government and has been the scene of violence in recent months.

After the incident Bjork said, “I stand by what I said.”
