SHANGHAI - China has more billionaires than any country except the United States, as soaring stock and property prices helped boost wealth among the country's super-rich, researcher Rupert Hoogewerf said on Wednesday.

The number of Chinese in the Chinese mainland worth $1 billion or more jumped to 108, from 15 last year, Hoogewerf said in his 2007 "rich list," which ranks the 800 wealthiest individuals in the Chinese mainland.
