LHASA, Sept. 8 -- Top Chinese political advisor Yu Zhengsheng on Tuesday called for managing religious affairs according to law and maintaining sound orders of Tibetan Buddhism.

In a speech marking the 50th anniversary of the founding of the Tibet Autonomous Region, Yu, chairman of the National Committee of the Chinese People's Political Consultative Conference, stressed upholding law-based governance in Tibet.

"Religious Affairs should be managed according to law; problems should be addressed through legal thinking and judicial means; and the good order in the worship of Tibetan Buddhism should be maintained," Yu said.

He continued by saying that the campaign against separatism and the crackdown on separatist and sabotage activities must also be carried out in line with laws.

Yu arrived in Lhasa, capital of Tibet Autonomous Region, on Sunday, leading a central government delegation to attend festivities marking the 50th anniversary of the region's founding.
