http://en.wikipedia.org/wiki/ShangrilaShangri-La is a fictional place described in the 1933 novel Lost Horizon by British author James Hilton. In the book, "Shangri-La" is a mystical, harmonious valley, gently guided from a lamasery, enclosed in the western end of the Kunlun Mountains. Shangri-La has become synonymous with any earthly paradise but particularly a mythical Himalayan utopia—a permanently happy land, isolated from the outside world. The word also evokes the imagery of exoticism of the Orient. The story of Shangri-La is based on the concept of Shambhala, a mystical city in Tibetan Buddhist tradition.
http://en.wikipedia.org/wiki/TibetExisting as a separate nation for centuries, Tibet is today administered mostly under the People's Republic of China. Tibet is also officially claimed by the Republic of China (Taiwan). However in the Tibetan sovereignty debate, the government of the People's Republic of China and the Government of Tibet in Exile disagree over when Tibet became a part of China, and whether this incorporation into China is legitimate according to international law.
Neither the Republic of China nor the People's Republic of China has ever renounced China's claim to sovereignty over Tibet.[18] In 1950, the People's Liberation Army invaded the Tibetan area of Chamdo, crushing minimal resistance from the ill-equipped Tibetan army. In 1951, the Tibetan representatives, under PLA military pressure, signed a seventeen-point agreement with PRC's Central People's Government affirming China's sovereignty over Tibet. The agreement was ratified in Lhasa a few months later.[19][20]
