The rich historical documents of China are more than enough to show
          one fact: the Tibetan nationality living on the Qinghai-Tibet
          plateau has long become one of the members of the Chinese nation and
          Tibet has been an inalienable part of China since ancient times.
          About this fact, all the people with an objective and just stand in
          the international community have already reached or been close to
          reach common consensus. However, it is still necessary to deepen
          this common consensus. The reason lies in the fact that the deposits
          of the history treasure house of China are so rich and generous that
          people will simply never know clearly of its each part without going
          on explorations on them in a thoroughgoing way. After the Chinese
          revolution of 1911, the history of relationship between the Tibet
          region and the central government of China is a key historical link
          which is worth to be studied of the real situation about the Tibetan
          contemporary and modern history by the world through examining this
          historical link. This article is to help the readers understand
          briefly the history of relationship between the Tibet region and the
          successive central governments of China after the Revolution of
          1911. The writer is convinced that the readers would have their own
          independent and logical judgements after reading the following
          historical facts to the reliability of the story of 'Tibet separated
          itself from China and became an independent country after 1911."
         
          As is known to all that as early as the seventh century in the Tang
          Dynasty, the Tibetan and Han peoples established close ties in the
          political, economic, cultural and other gelds through the royal
          inter-marriages, meetings of sovereigns or their deputies in ancient
          China to form alliances, thereby laying down the historical
          foundation for finally establishing the unified country.
         
          In the middle of the thirteenth century,Tibet was formally
          incorporated into the Chinese territory of the Yuan Dynasty, Yuan
          Emperor Kublai entrusted to the Sakya Sect the power of
          administering the Tibet region, setting up the General Council
          (renamed Political Council in 1288) which was a central government
          organ exercising administrative power over the country's Buddhist
          affairs and the Tibetan affairs, The Yuan government instituted the
          system of imperial preceptor, conferred titles on political and
          religious leaders, delimited administrative divisions, appointed
          local officials, took census, collated and stipulated revenue and
          taxes, dividing the Tibet region into thirteen Wan Hu (ten thousand
          households). The heads of Wan Hu were conferred upon and appointed
          directly by the Yuan Court. There were three Chief Military Commands
          of the Pacification Commissioners' Offices which took charge of
          garrison troops and the administrative affairs of the various Wan Hu
          Offices in Tibet proper and other Tibetan areas.
         
          In the later period of the fourteenth century, the central
          government of the Ming Dynasty inherited and followed the systems of
          adminstering Tibet by the Yuan Dynasty, pursued a policy of
          "managing Tibet according to conventions and customs, granting more
          titles and setting up more organs." Hence, the relations between
          Tibet and the central regime were further consolidated and
          strengthened.
         
          From the seventeenth century onwards, the Qing government further
          strengthened its administration over Tibet. In 1721 the system of
          Kalon (Council Minister) in charge of administrative affairs was set
          up. In 1727 the Office of Amban (Resident Official) was instituted
          in Tibet. In 1792 the twenty-nine-article Imperial Ordinance was
          issued. It stipuIated in explicit terms for the reincarnation of the
          Living Buddhas in Tibet as well as the administrative, military and
          foreign affairs. The Imperial Ordinance marked that the
          administration of the Tibet region by the Qing central government
          was upgraded to the level of systematization and legalization.
         
          In late Qing period, Britain twice launched armed invasions against
          Tibet. The Chinese government was forced to sign unequal treaties
          relating Tibet, After the Revolution of 1911 , the political
          situation of China was turbulent. In order to realize its aim of
          splitting Tibet from China and reducing it into a dependency of the
          British Indian government, Britain adopted various acts of
          aggression against Tibet. Owing to the instigation of Britain, the
          relations between the Tibet region and the central government of
          China were for a time abnormal during the period of the Republic of
          China. Although the British impedalists attempted to split China and
          to grab Tibet, its schemes never succeeded. On the contrary, they
          were opposed and boycotted by the broad masses of the Chinese
          people, including the majority of the Tibetan upperstrata figures.
          Tibet was not officially recognized as "an independent country" by
          any country through diplomatic channels in the world at that time,
          including even the schemers themselves. The Tibet region also never
          detached itself from the sovereign jurisdiction of the central
          government and became "independent".
