New rules are coming into force giving the Chinese government more influence over how Tibetan monks select their spiritual leader, the Dalai Lama.
Most Tibetans believe Dalai Lamas are reincarnated after their deaths.
But the new regulations mean future reincarnations must be approved by China's Communist government.
The current Dalai Lama has already nominated a successor, while the government named a different child. Both are reportedly in hiding.
