Mayor Wang Anshun, largely responsible for Beijing’s successful Olympic 2022 bid, has been replaced in the role by Cai Qi. It is believed that he will head into semi-retirement in a government think tank, before he reaches 65, the mandatory retirement age. The demotion could be taken as a criticsm of Wang’s close links with disgraced official Zhou Yongkang, or equally of his failure to deal with Beijing’s notorious air pollution issues during his time in office.
