Pang Guixiong, 46, jumped out of a window of his apartment on the 23d floor of a residential building on Wednesday in the Guangdong Province port city of Zhanjiang.
Xhinhua cites sources within his company as saying that the man was suffering severe stress over "increasing pressure from a growing number of creditors for immediate repayment of company debts."
The debts of the sugar giant have grown to about 1 billion yuan ($150 million) due to losses from futures trading. In January, the sugar price was 5,300 yuan ($775) a ton, but it has since almost halved to 2,800 yuan ($410) a ton.
An investigation is underway and all the assets of the company, which owns sugar plantations, refineries, transport and storage facilities, have been frozen.
