China is notorious for its efforts to control things in Tibet but the law that the Chinese government passed in 2007 was beyond absurd. According to the law it’s illegal for Tibetan Buddhist monks to reincarnate without the government´s permission.

On 3 August 2007 China’s State Administration for Religious Affairs issued a decree that all reincarnations of Tibetan Buddhist monks must have government approval, otherwise they are “illegal or invalid”. The decree states

It is an important move to institutionalize management on reincarnation of living Buddhas. The selection of reincarnates must preserve national unity and solidarity of all ethnic groups and the selection process cannot be influenced by any group or individual from outside the country.

It also requires that temples which apply for reincarnation of a living Buddha must be

legally-registered venues for Tibetan Buddhism activities and are capable of fostering and offering proper means of support for the living Buddha.

Reincarnation applications have to be submitted to four governmental bodies for approval: the religious affairs department of the provincial-level government; the provincial-level government; State Administration for Religious Affairs; and the State Council.
All of which is sadly part of China’s efforts to sideline the current Dalai Lama and take control of the selection (when the time comes) of both the Dalai Lama and Panchen Lama.
