Yu-chien Kuan or Guan Yuqian (Chinese: 关愚谦; 18 February 1931 – 22 November 2018) was a Chinese-born German sinologist, writer and translator. The son of a high-ranking Chinese Communist Party official, he was denounced as a "rightist" and persecuted during the Anti-Rightist Campaign and the Cultural Revolution. This drove him to escape from China using a Japanese passport stolen from his workplace. He landed in Egypt and spent a year and half in prison for illegal entry, before being admitted to West Germany in 1969 as a political refugee.
