It warns local people to be on the lookout for the 'evil forces' of the Dalai Lama that might use local temples and religious control "to confuse and incite" people against the Party and government.
The bureau is asking people to report on the activities of 'foreign hostile forces' that may seek financial support for the Dalai Lama"
"Criminal gangs are cancers on the healthy economic and social development, and gangsters are a chronic disease that severely disgusts the public," the circular reads.
The circular listed 22 illegal activities the bureau wants people to report, three of which directly mentioned the Dalai group. The Dalai Lama has been in exile for decades but still hold ambition to split China's Tibet from the Chinese territory.
The circular echoes the primary task of Tibet, which is to maintain national and ethnical unity, said Wang Xiaobin, a scholar at the Beijing-based China Tibetology Research Center.
"Collusion with criminal gangs is a tactic the Dalai group uses to spreading its message of separatism. These kinds of gangsters were involved in the Lhasa rebellion in the 1950s and the violent accident in 2008 in Tibet," a professor who researches religious studies at Public Security University of China, surnamed Dai, told the Global Times on Sunday.
Due to lack of development and legal knowledge, the spread of separatist gangs in Tibet is rampant, said Dai, adding that a campaign against the gangsters would deter off secessionist activities by the Dalai.
There are groups in China that are closely connected with the Dalai group, and help each other at home and abroad. They challenge the Chinese government using ingenious methods and pose a huge threat to national interests, Wang told the Global Times on Sunday.
"The Dalai group always interferes in national affairs by controlling temples, including lamas and living Buddhas, and by spreading a kind of "middle way" to the world, which actually advocates separatism and emphasizes the separation of sovereignty and governing rights," Wang explained.
The tip circular released by the Tibet security bureau comes after the Communist Party of China Central Committee and the State Council in January announced a renewed effort to fight organized crime and officials who shelter criminal organizations.
The campaign would involve fighting corruption, including lower-level corrupt officials, and deal with the "protective umbrellas" of gang crime (the officials who shelter the criminals), the Xinhua News Agency reported.
Fight against ethnic extremism
The targets are gangsters who threaten political security and infiltrate politics, or encourage the public to go against the Party and government under the disguise of religion, or prompting ethnic extremism.
Hostile forces and some intellectuals who advocate "protecting the local language," are attempting to spread the false notion that the Chinese language is destroying Tibetan culture, Wang said, adding that the government has made huge efforts to protect Tibetan culture and languages. "Ethnic extremism is an ideology that has unfathomable consequences," said Wang.
The public security departments will protect tipsters' identity and safety, the circular reads.
