Beijing  - China's booming property and stock markets have helped expand the number of dollar billionaires to 130, up from 101 a year ago, the Shanghai-based Hurun Report said Tuesday.

"China's super-rich seem to have put the credit crunch behind them," Hurun said in its annual China Rich List of the country's wealthiest entrepreneurs.

Rebounding property prices and stocks pushed the total wealth of the 1,000 richest Chinese listed to 571 billion dollars, up 130 billion dollars from last year, the report said.

"China's wealth is growing at breakneck speed," said Rupert Hoogewerf, who complied the Rich List.

"Since our 2004 list, we have seen a 10-fold increase in the number of individuals with personal wealth of at least 150 million dollars," Hoogewerf said, adding that China was second only to the United States in its number of known dollar billionaires.

"You can double the real number of billionaires in China to 260," he said.

"There are still a large number of billionaires off the radar screens, managing to build up substantial wealth away from the public spotlight from property, the stock market and investments."

China's richest person this year is Wang Chuanfu, 43, with estimated wealth of 5.1 billion dollars accumulated mainly from his BYD high-technology firm, which has specialized in batteries for mobile telephones and electric vehicles.

"Wang Chuanfu has made it to number one in China on the combination of a 30-per-cent growth of the Chinese car industry and the Warren Buffett Midas touch," said Hoogewerf, referring to the fact that shares in Hong Kong-listed BYD soared last year after US-entrepreneur Buffett announced plans to buy 10 per cent of the firm.

Paper recycler Zhang Yin, who in 2006 became the first woman to head the list, climbed back up to second place this year.

The man listed at the top of last year's China Rich List, electronics tycoon Huang Guangyu, was later detained over alleged share-price manipulation. (dpa)
