Cai Qi, aged 70, is currently serving as the Chief of Staff to Chinese President Xi Jinping, a role that positions him as one of the most powerful figures in the Chinese Communist Party (CCP). His influence is underscored by his rapid promotions and long-standing ties with Xi, dating back to their time in the Fujian province. Cai has been responsible for managing Xi's daily schedule, internal communications, and the organization of significant political events since his appointment in March 2023. His rise to power has been marked by a series of strategic positions, including his role as the mayor of Beijing and later as the party secretary, where he implemented Xi's priorities. However, the dynamics within the Politburo remain fluid, and analysts caution against labeling Cai as Xi's definitive No. 2, given the ongoing anti-corruption purges that have seen other prominent figures removed from power. This context suggests that while Cai is a key ally, the nature of political loyalty in China is complex and precarious.
