BEIJING, Nov 15 (AFP) - China's top officials on Tibet have made a mass denunciation of the region's exiled spiritual leader, the Dalai Lama, and accused him of promoting feudal superstitions to split the motherland.

The official Tibet Daily seen here Friday said communist cadres who attended a lengthy regional meeting in Lhasa condemned the Dalai Lama for using "old feudal customs" to disrupt the thinking of the masses.

Only days after Tibet party chief Chen Kuiyuan launched the "final attack" on the Dalai Lama, the cadres unanimously vowed to launch a tit-for-tat struggle against "the Dalai clique's use of superstitious beliefs to disrupt people's thinking."

The meeting blamed the Dalai Lama for encouraging polygamy and marriages between close relatives which "contravene science and endangers the development of Tibetans."

"Some superstitious beliefs have been revived ... and we should eliminate this vicious influence," an unnamed cadre told the newspaper's November 7 edition.

The article warned that China's efforts to boost science and technology in the remote, mountainous region would be ruined unless superstition was eliminated.

"If the education campaign gives the feudal superstition an inch, it will take a mile," it said.

In language reminiscent of 1950s rhetoric, it quoted cadres as saying that Buddhist monks were acting as witch-doctors, while the Tibetan people had become lazy and begged shamelessly.

"We must expose and strike hard any superstitious and religious speeches or practices which disrupt the everyday life of the masses. We should totally smash old customs which are closely associated with religious beliefs," said Bai Lang, party secretary of Nanmulin county.

"The party should pay absolute attention and vigilance, and carry out an all-out powerful media and education campaign, and guide and rule people with strict laws," the newspaper added.

On November 4, the Tibet Daily published a full-page article calling for "large-scale" reforms of existing religious policy in Tibet, saying a lack of administrative control in recent years had led to chaos in some regions.

It called for an all-out offensive on temples, monks and nuns that have fallen under the "splittist" influence of the Dalai Lama.
