Katy Perry, who was set to perform, has now been banned from China indefinitely. The decision apparently was taken after the government caught wind of a controversial incident from 2015, in which Perry wore a bright, glittery dress with sunflowers on it during a performance in Taipei, the capital of Taiwan. Her outfit wound up causing widespread outrage because the sunflower had been adopted the year before by anti-China protesters. IN PIC: Katy Perry (Photo | AP)
