Katy Perry is banned from China
Katy Perry is banned from China because she waved a Taiwanese flag during her concert in Taipei in 2015. China is not in good relationship with Taiwan.
A source explained, “She was initially granted a visa to perform at the VS show in Shanghai, then Chinese officials changed their minds and yanked her visa. For every artist who wants to perform in China, officials comb through their social-media and press reports to see if they have done anything deemed to be offensive to the country.
