Cardinal Joseph Zen (C), an outspoken critic of Beijing, along with other protesters takes part in a demonstration to demand religious freedom in China outside the China Liaison Office in Hong Kong July 11, 2012. The Vatican on Tuesday condemned the appointment of a Chinese Catholic bishop without its approval, hours after a source said one of Rome's own newly-ordained bishops had been detained in a seminary in China.
