Duan Weihong
Duan Weihong (; born 29 December 1966), also known as Whitney Duan, is a Chinese billionaire who is currently missing and believed to be held captive by Chinese government investigators on corruption charges. Prior to her arrest at Beijing’s Bulgari Hotel she owned, she was subject to a travel ban by the Chinese government. According to a 2018 report from "The New York Times", Duan was detained in 2017, possibly in relation to an anti-corruption investigation into Sun Zhengcai, but there has been no official acknowledgement from the Chinese government. Duan, who was reported to be one  of China’s wealthiest women, was known for her business dealings with former Chinese premier Wen Jiabao and particularly his wife, Zhang Peili. In a memoir written by her ex-husband Desmond Shum titled Red Roulette, Duan is said to have fallen victim to the party’s use of "extralegal kidnappings" to facilitate opaque investigations. However in the book Shum states that arresting and holding suspected high-level criminals for unlimited time is legal in China; this especially applies to Communist Party members suspected of corruption by party investigators. Shum also openly admits virtually all of his own and his  former wife’s business deals in China were corrupt. In an interview with NPR, Shum stated that he had received a call from Duan urging him not to publish his book, a request that he said was made under duress.
