FACTBOX - Tibet, the Dalai Lama and relations with China

(Reuters) - Chinese security forces did not use lethal weapons on protesters in Tibet's capital, Lhasa, the region's governor said, as troops poured into neighbouring provinces to quell copycat rioting by Tibetans.

Chinese officials have declared a "people's war" of security and propaganda against support for the Dalai Lama in Tibet after protests turned into riots last week.

The demonstrations had marked the 49th anniversary of a failed uprising against Communist rule.

Following are some facts about Tibet, the Dalai Lama and relations with China:
