HONG KONG — Canada’s outspoken Miss World contestant said she was barred Thursday from entering China to take part in this year’s pageant and accused Beijing of overreach in extending its campaign of censorship even to beauty contests. Lin is an outspoken critic of Chinese religious policy and a follower of the Falun Gong meditation practice, which was outlawed by China’s ruling Communist Party in 1999. Dressed in black leggings and a belted tan trench coat, Lin was approached by several fellow travelers in the Hong Kong airport arrival hall who wanted to take her photo. Lin said that after she won the Canadian title, Chinese security agents visited her father who still lives in China in an apparent attempt to intimidate her into silence.
