Ancient texts preserved in Tibet's Potala Palace

China plans to spend 300 million yuan ($45 million) over the next 10 years to preserve ancient documents and anthologies at the Potala Palace in Lhasa, capital of the Tibet autonomous region, the palace's administration office said on Tuesday.

The preservation project, starting this year, will be the largest of its kind at the palace complex.

The central government has been working to preserve Tibet's cultural relics over the past few decades, including the Potala Palace itself, one of three UNESCO World Heritage sites in the region.
