BEIJING, Sept. 4(Xinhua) -- A collection of documents on southwest China's Tibet Autonomous Region, including decisions of the central authorities, laws and regulations and speeches and letters by Chinese top leaders on Tibet, was published Thursday.

    Documents in the book, published by the Central Party Literature Publishing House, cover the period from September 1949 to May 2005. Many of the documents were made public for the first time.

    "These documents rather systematically reflect the guidelines, principles and major decisions of the central authorities on work in Tibet," said an official of the house.

    "They also comprehensively display the progress of a united, prosperous and civilized socialist new Tibet," he said.

    Publication of the documents coincide with celebrations of the 40th anniversary of the founding of the Tibet Autonomous Region. Enditem
