LHASA, May 30 (Xinhua) -- The Tibet regional government will increase funding for the protection of cultural heritage as its fiscal revenue rises, said Qiangba Puncog, chairman of Tibet Autonomous Region, Tuesday.

He made the remarks when explaining a drafted revision to a government regulation at a meeting of the regional people's congress standing committee. The committee was reviewing the revised regulation on protecting Tibet's cultural heritage, submitted to it by the regional government.

The revised regulation clarifies the government's role in supervision, management and protection of cultural heritage, the chairman said.

The regulation stipulates that tourism incomes of state-owned museums and memorial halls must be used on cultural heritage protection.

The new rules also call for better protection of state-owned cultural heritage that is located in religious sites and stipulate that the state ownership must not be changed under any conditions.

The rules stipulate that all signs at cultural heritage sites must be in both Tibetan and Chinese languages.
