The rules say that the background credentials of performers from foreign countries, Hong Kong, Macao and Taiwan will be scrutinized. “Those who used to take part in activities that harm our nation’s sovereignty are firmly not allowed to perform in China,” the rules say.
They also call for barring performers who promote ethnic hatred or “advocate obscenity or feudalism and superstition.”
According to the report, the ban also applies to artists from Hong Kong and Macao.
