Nine out of ten yuan spent by local finance of Tibet has come from the central revenue, said Qiangba Puncog, chairman of Tibet autonomous regional government, at a news briefing on Tibet's social and economic development.

The funds used in Tibet's infrastructure construction and for its fiscal expenditure over the last 50 years have mainly allocated by the central government, said the chairman.

The central government will invest 77.8 billion yuan (10.23 billion US dollars) in 180 projects in Tibet between 2006 and 2010.

"These projects will improve local infrastructure and the living and production conditions for local farmers and herdsmen, which will in turn lay a solid foundation for a faster development in Tibet," said the official.

"At the moment, we are committing ourselves to fast economic development while persisting in the concept of "people first" and the scientific concept of development," said Qiangba Puncog, "Tibet'll realize the great target of building a better-off society in an all-round way together with the rest of the country by 2020."
