Does China have Vatican City in its sights?

Last Sunday the Vatican released the first photograph of Pope Francis since his ordeal began. He was wearing a stole around his neck, indicating that he had concelebrated mass in the chapel of the Gemelli hospital. Admittedly, all he had to do was raise his hand and whisper a few words of consecration, but it would have been impossible to take such a photo a week earlier, when Vatican-watchers were checking their phones hourly to discover whether the See of Peter had become vacant.
