BEIJING • All religious artefacts in places of worship in Tibet belong to the Chinese state, the official Xinhua news agency said yesterday, in Beijing's latest attempt to exert control over religion in the restive Himalayan region.

Beijing is particularly wary of religious groups, such as Buddhists, and has jailed Tibetan monks and nuns it accused of stoking "separatism".

Tibet's cultural heritage suffered during the chaos of the 1966-79 Cultural Revolution, when fanatical Maoist Red Guards smashed religious symbols and destroyed monasteries. Some have since been rebuilt.

The decree on artefacts is part of revised rules on protecting Tibet's cultural heritage, Xinhua said.

"Relics collected or taken care of in places of religious activity in the autonomous region, or provided for the use of religious personnel by national artefact collection departments, belong to the state," Xinhua quoted the revised rules as saying.

That rule was needed due to the "special situation of preserving the existence of Tibet's relics", the report added, without elaborating.

The new rules also stipulate that all explanatory signs at cultural sites must be in Tibetan as well as Chinese.

The Tibetan language is meant to have equal status with Chinese in Tibet, although in practice few non-Tibetans understand it and many complain it is being marginalised.
