LHASA, Oct. 22 -- Since 2021, southwest China's Xizang Autonomous Region has spent 20.16 billion yuan (2.83 billion U.S. dollars) on cultural tourism infrastructure, national park conservation facilities, and the preservation and improvement of its historic towns, a local official said on Tuesday.

Of the funds, 1.97 billion yuan was spent on construction projects, including a regional planetarium, an art museum, and a culture, radio, television and art center, according to Weiqiang, director of the regional development and reform commission, at a regional conference on cultural tourism development.
