Billions in Hidden Riches for Family of Chinese Leader

The Tycoons

In the late 1990s, Duan Weihong was managing an office building and several other properties in Tianjin, the prime minister’s hometown in northern China, through her property company, Taihong. She was in her 20s and had studied at the Nanjing University of Science and Technology.

Around 2002, Ms. Duan went into business with several relatives of Wen Jiabao, transforming her property company into an investment vehicle of the same name. The company helped make Ms. Duan very wealthy.

It is not known whether Ms. Duan, now 43, is related to the prime minister. In a series of interviews, she first said she did not know any members of the Wen family, but later described herself as a friend of the family and particularly close to Zhang Beili, the prime minister’s wife. As happened to a handful of other Chinese entrepreneurs, Ms. Duan’s fortunes soared as she teamed up with the relatives and their network of friends and colleagues, though she described her relationship with them involving the shares in Ping An as existing on paper only and having no financial component.

Ms. Duan and other wealthy businesspeople — among them, six billionaires from across China — have been instrumental in getting multimillion-dollar ventures off the ground and, at crucial times, helping members of the Wen family set up investment vehicles to profit from them, according to investment bankers who have worked with all parties.

Established in Tianjin, Taihong had spectacular returns. In 2002, the company paid about $65 million to acquire a 3 percent stake in Ping An before its initial public offering, according to corporate records and Ms. Duan’s graduate school thesis. Five years later, those shares were worth $3.7 billion

The company’s Hong Kong affiliate, Great Ocean, also run by Ms. Duan, later formed a joint venture with the Beijing government and acquired a huge tract of land adjacent to Capital International Airport. Today, the site is home to a sprawling cargo and logistics center. Last year, Great Ocean sold its 53 percent stake in the project to a Singapore company for nearly $400 million.

That deal and several other investments, in luxury hotels, Beijing villa developments and the Hong Kong-listed BBMG, one of China’s largest building materials companies, have been instrumental to Ms. Duan’s accumulation of riches, according to The Times’s review of corporate records.

The review also showed that over the past decade there have been nearly three dozen individual shareholders of Taihong, many of whom are either relatives of Wen Jiabao or former colleagues of his wife.

The other wealthy entrepreneurs who have worked with the prime minister’s relatives declined to comment for this article. Ms. Duan strongly denied having financial ties to the prime minister or his relatives and said she was only trying to avoid publicity by listing others as owning Ping An shares. “The money I invested in Ping An was completely my own,” said Ms. Duan, who has served as a member of the Ping An board of supervisors. “Everything I did was legal.”

Another wealthy partner of the Wen relatives has been Cheng Yu-tung, who controls the Hong Kong conglomerate New World Development and is one of the richest men in Asia, worth about $15 billion, according to Forbes.

In the 1990s, New World was seeking a foothold in mainland China for a sister company that specializes in high-end retail jewelry. The retail chain, Chow Tai Fook, opened its first store in China in 1998.

Mr. Cheng and his associates invested in a diamond venture backed by the relatives of Mr. Wen and co-invested with them in an array of corporate entities, including Sino-Life, National Trust and Ping An, according to records and interviews with some of those involved. Those investments by Mr. Cheng are now worth at least $5 billion, according to the corporate filings. Chow Tai Fook, the jewelry chain, has also flourished. Today, China accounts for 60 percent of the chain’s $4.2 billion in annual revenue.

Mr. Cheng, 87, could not be reached for comment. Calls to New World Development were not returned.
