Duan Weihong

Duan Weihong (; pinyin: Duàn Wěihóng; born December 29, 1966), also known as Whitney Duan, is a Chinese billionaire. She is known as a business partner of the family of former Chinese premier Wen Jiabao. Duan was secretly detained in 2017 and resurfaced in 2023.

In a memoir written by her ex-husband Desmond Shum titled Red Roulette, Duan cultivated extensive political and business connections in China, especially with Zhang Peili, Wen's wife. Duan was secretly detained on 5 September 2017, possibly at the order of Wang Qishan in relation to an investigation into Sun Zhengcai, both her cultivated connections. She is said to have fallen victim to the Chinese Communist Party's use of "extralegal kidnappings" to facilitate opaque investigations. Shortly before Red Roulette was published, Shum received a call from Duan—her first contact with the outside world since her disappearance in 2017—asking him to cancel the publication out of concern for their son's safety. Shum refused, believing she was under duress to make the phone call.
