Once the owner of China's largest refrigerator maker, Gu Chujun was proud of his ability to manipulate the stock market, but now he has to pay for it.

On January 30, the former Chairman of Guangdong Kelon Electrical Holdings Co. was sentenced to 12 years in jail by the Foshan Intermediate People's Court in south China's Guangdong Province. The 49-year-old was convicted of misreporting registered capital, withholding information and embezzling 353 million yuan ($49 million) from companies under his control.

Since judicial proceedings against Gu had lasted for more than two years until the court announced its ruling, Gu is to serve only the remaining 10 years' jail time. The court also imposed a fine of 6.8 million yuan ($944,000).

Seven other people who had assisted Gu in committing his criminal acts also received prison terms ranging from one to four years.

Gu started up his own business in the late 1980s with a proprietary refrigerant technology. In 1995, he invested $50 million to build then Asia's largest CFC-free refrigerant production base in north China's Tianjin. Around 2000, Gu became active in China's capital market and acquired Kelon, a state-owned appliance giant with assets then valued at 6.6 billion yuan ($814.8 million) and yearly revenues of 4.38 billion yuan ($540.7 million), in October 2001. In the following years, he purchased three other listed companies, founding a business empire encompassing refrigerator manufacturing and auto making.

However, in 2004, Larry H. P. Lang, professor of economics at the Chinese University of Hong Kong, accused Gu of overstating profits and engaging in dubious deals to purchase state assets at a discounted price. Lang's claim sparked hot debate in the academic community, and the state securities regulator began to investigate relevant equity transactions.

Gu was detained in July 2005 on charges of embezzlement and fraud. Two months later, the heavily indebted Kelon was acquired by rival Qingdao Hisense Air-Conditioning Co.

The China Securities Regulatory Commission announced in July 2006 to ban Gu from investing in the stock market and holding any position in a listed company for life.
