MANILA, Aug 31 (AFP) - An exiled Tibetan activist has compared the present situation in Tibet with the run-up to China's Cultural Revolution in a report released at a conference here Saturday.

Gedun Rinchen, based in India, was refused entry to the Philippines to address the conference, together with a second Tibetan, Tampa Tsering.

Organizers of the International NGO Forum on Human Rights in China, co-sponsored by Amnesty International and the Bangkok-based Asian Forum for Human Rights and Development, have attributed the decision to refuse them entry to pressure from China, which annexed Tibet in 1950.

"In terms of politics and religion, the present situation in Tibet is gradually coming to look similar to conditions in the run-up to the Cultural Revolution," Rinchen said in his report.

Rinchen, who formerly worked as a tour guide in Tibet, said Chinese officials recently went to the Gaden monastery and ordered the monks to take down photographs of the Dalai Lama, the exiled spiritual head of Tibetan Buddhism, now living in India.

When they refused the Chinese shot at the monks, killing one and wounding another, he said, adding 60 monks were arrested and another 600 fled and are being hunted by authorities.

Rinchen did not give the source of his information.

He also charged that in 1994 many monks and nuns had been forced to leave their monasteries and many of the monks were vetted. Only those considered loyal to China were allowed to stay in the monasteries.

"Freedom of religion to Chinese authorities seems to me to mean having a monastery with a few monks in it, like a museum," he said.

"Chinese security forces are using more sophisticated methods to torture, which leave no mark on the body, so it is getting harder and harder to document."

Rinchen said international pressure could have an effect on China's treatment of Tibetans.
