The Dalai Lama turned 90 on Sunday and people in the Himalayan town of McLeod Ganj are celebrating. But the spiritual leader’s growing age is also raising concerns about the survival of the Tibetan movement after he passes on.

China still controls the region, and critics say Beijing is now trying to change Tibet’s ethnic identity; by forcing Tibetan kids into colonial-style boarding schools and moving mainland Chinese into Tibet. In a pre-recorded video that aired last week, the Dalai Lama announced plans for a successor. In what appears to be a nod to China, the English translation on his website adds that "no one else has any such authority to interfere in the matter." China has stated that it alone has the authority to appoint the next leader of Tibetan Buddhism.
