Writing in Foreign Policy, Chinese political commentator Deng Yuwen argues that outside observers have repeatedly misjudged Xi's rule by focusing on imagined power struggles while overlooking how the system functions daily. The analysis contends that Xi cannot personally manage the entire state and party machinery and needs trusted lieutenants. Within the 20th Politburo, Li Qiang and Cai Qi are described as Xi's two most indispensable aides: Li overseeing government affairs, Cai overseeing party affairs.
The article draws a parallel to an observation by former Premier Zhou Enlai, who advised senior commanders to understand the relationships among Mao Zedong, military leader Lin Biao and Mao's wife Jiang Qing. In the current era, the analysis says, Xi, Li and Cai form a similarly unequal triangle, with Xi as the supreme authority over both men. However, the author stresses critical differences: neither Li nor Cai possesses the independent political capital that Lin commanded nor the familial connection that gave Jiang her standing. Both owe their ascent to trust built with Xi during their careers in provincial and central government, and neither can establish independent power centres outside Xi's authority.
Since the 20th Party Congress in 2022, responsibilities have been divided: Li serves as premier and ranks second in the party hierarchy, while Cai, ranking fifth, heads the powerful General Office of the CCP Central Committee and this year took charge of the Central Party School. The analysis notes that while Cai's proximity to Xi confers influence, the division of work prevents either man from monopolising power. Key party functions such as discipline inspection, propaganda and security are overseen by other Xi loyalists who report directly to the leader. The transfer of Shi Taifeng to head the Central Committee Organisation Department last year is cited as a move that objectively limits Cai's ability to build a personal power base.
The article dismisses speculation that Li Qiang or Cai Qi have been designated Xi's successor, arguing that neither claim is credible. Instead, the analysis frames the relationship as one of tightly controlled delegation, with Xi retaining final authority over anti-corruption campaigns, political standards and ideological education.
