China’s 21st Party Congress set for major leadership overhaul

Following the conclusion of the “Two Sessions” in mid-March, the Chinese political clock will start in preparation for the important once-every-five-years National Congress of the Chinese Communist Party (CCP). This upcoming 21st Party Congress in the latter half of 2027 will preside over what is anticipated to be one of the largest leadership reshufflings in the history of the People’s Republic of China (PRC). 

Bound by institutionalised norms such as age limits, it is expected that more than two-thirds of Central Committee (CC) members will be replaced, with a similar turnover rate expected in the powerful Politburo. The Politburo Standing Committee (PSC), China’s supreme decision-making body, will likely have four to five new members. 

With the notable exception of General Secretary Xi Jinping, who will remain, the generation that grew up during the Cultural Revolution will depart from leadership. This projected high turnover rate among top leadership is not a contingency, but rather the result of both longstanding institutionalised developments within the CCP and the new emphasis on strict party self-discipline (从严治党) in the Xi Jinping era.

Throughout the history of the PRC, changes in the composition of the political elite have often reflected — and sometimes heralded — broader transformations in economic, sociopolitical and strategic dynamics. Central to any analysis of China’s political trajectory is an understanding of the institutional mechanisms undergirding generational transitions within leadership bodies and the characteristics of the new cohort of officials who will govern the country. 

This is particularly important today, at a time when China is encountering what the Chinese leadership keenly acknowledges as a rapid socioeconomic and technological transformation at home, and daunting challenges in the geopolitical environment abroad. The Chinese leadership is evidently determined to show the world China’s political continuity, economic development certainty, social stability and diplomatic gravity.

The international community will closely monitor the transition and composition of the 21st CC, the institutional core of China’s party-state system. Three elements will shape the 2027 transition: 1) the status of current members of the 20th CC, 2) recent large-scale purges over corruption charges across military and civilian leadership, and 3) institutional norms regarding personnel appointments provide critical insights into a system often perceived as a “blackbox”. 

This sort of tangible evidence not only reflects the most current operational logic of CCP leadership but also directly affects the formation of the new leadership bodies. The empirical data underlying this paper’s analysis is drawn from the “China-US Leadership at a Glance” database, an interactive bilingual platform of verifiable public information on Chinese and American leadership maintained by our centre, recently created with the objective of countering misinformation and promoting fact-based analysis.

The age limit norm is one of the most definitive mechanisms for determining personnel promotion or retirement in China’s party-state system. The historical record demonstrates the consistency of this rule. At the 18th Party Congress in 2012 and 19th Party Congress in 2017, the retirement age threshold was enforced without exception across all 350 plus members of the CC — no leader born before 1945 and 1950 respectively remained in the newly formed CC. 

The age-limit rule was largely upheld at the 20th Party Congress in 2022, with only three members born before 1955 remaining: Xi Jinping (1953), Wang Yi (1953), and Zhang Youxia (1950). These three exceptions represented less than 1% of the 376-member leadership body. When the CCP holds its 21st Party Congress, the age restriction threshold will most likely be set at 1960, meaning that leaders born before 1960 will, in principle, retire. There will likely be only a few exceptions.

Looking ahead to 2027, the average age of members of the PSC, Politburo and Secretariat will reach 70.3, 68.6, and 68.3, respectively, by the time the new congress convenes (see Chart 1). When measured against the 1960-threshold, Chart 1 shows that the average age in all three of these high leadership bodies either meets or exceeds the 67-year retirement line, suggesting that most current members will be institutionally obligated to step down.

Departures at the very top will, in turn, open the door to a new generation. Leaders born in the 1960s will form the primary age cohorts in the PSC, Politburo and Secretariat. The CC will be largely composed of members born in the 1970s (particularly alternate members), and many will take top provincial and ministerial leadership positions. This age-based system steadily implements the CCP’s longstanding practice of absorbing and cultivating young leaders, ensuring upward mobility opportunities. 

Generational replacement of leaders also carries potential policy implications. Those born in and after the 1960s grew up during the era of reform and opening up. Most of them began their undergraduate education and professional careers after 1978, which may lead to different policy preferences and governing styles compared to their predecessors.

The exceptions that are made at the 21st CC may approximate those of the 20th, though the outcome of any exceptions remains uncertain. For instance, General Zhang Shengmin, the current Central Military Commission (CMC) vice-chairperson and secretary of the CMC Discipline Inspection Commission, was born in 1958 but could be retained to preserve some continuity given the extensive ongoing military changes. 

Overall, the reform-era institutional mechanisms for elite recruitment have not been abandoned, and most retirements due to age limits will still be reliably forecasted through empirical methods.

The extensive corruption purges, which have been consistently implemented since the 20th Party Congress, are another significant cause of personnel changes. As of February 2026, data shows that of the 376 full and alternate members of the CC, 55 members (14.6%) have been fired. Furthermore, of the 133 members of the Central Commission for Discipline Inspection (CCDI), 9 members (6.8%) have been removed (see Chart 2).

This includes several high-ranking officials who held important positions in the Politburo, the State Council and the CMC, as well as in top provincial leadership. In terms of both the number and rank of officials dismissed, the intensity of corruption crackdown efforts since 2022 is no less than in the early years of the Xi administration (see Chart 2), reinforcing its governing philosophy of strict party self-discipline. 

Meanwhile, data shows that anti-corruption efforts have been broad in scope, with officials investigated and dismissed in fields beyond the military, including the diplomatic, financial, industrial and educational branches of the State Council, as well as provincial-level government. The establishment of the National Supervisory Commission in 2018, as part of a series of reforms to China’s anti-corruption system, indicates that the disciplinary inspection mechanism has been effective in covering a wide range of cases from a broad spectrum of institutions. These dismissals function as an accelerant of elite exits, which has increased the scale of turnover beyond what age limits alone would generate.

Table 1 provides an overview of the specific composition of anticipated turnover on the current CC. As of February 2026, among the 376 members of the 20th CC, 55 have been purged — comprising 43 full members (21% of full members) and 12 alternate members (7% of alternates) — accounting for 14.6% of the total body. Recent major personnel changes have been due to the military’s anti-corruption campaign. While some cases of dismissal have been formally documented in official records, others remain unverified by authoritative sources. However, in these cases, their absence from public events provides compelling circumstantial evidence of their removal. Among these 55 dismissed individuals, 34 came from the military. 

In addition, the data identifies a substantial outgoing cohort: 103 members of the CC — including 47 full members (22.9%) and 56 alternates (32.8%) — have either already been, or are highly likely to be, retired or moved to ceremonial positions (see Table 1). This group currently makes up 27.4% of the total body, but the number will likely climb between now and the second half of 2027. 

Furthermore, many officials whose statuses are unclear are largely constrained by age limits. The retirement age limit varies depending on the rank of the leader, and they face a “promotion-or-leave” arrangement, meaning that if they are not promoted to a higher rank, they will be required to retire or be moved to ceremonial positions awaiting retirement. 

The promotion of alternate members to full members will also be counted in the new leader calculation, as it will create vacancies in the alternate member pool and change the list of full members. This article estimates that a total of 51 alternate members (13.6% of the total body) will be promoted to full membership based on an assessment of factors such as age, tenure, position and leadership experience. Ascensions that reflect promotions were already made at the Third and Fourth Plenums of the 20th Party Congress. The Fifth Plenum late this year will further provide a window into this aspect.

Accounting for dismissals, retirements, promotions from alternate to full members, and deaths, and assuming half of those with unclear futures will depart, the CC turnover rate already stands at roughly 61%. 

Chart 3 shows that turnover rates at comparable party congresses over the past 40 years have consistently exceeded 60%. Among them, the 19th Party Congress saw the highest turnover rate, reaching 75%, as it partly inherited the institutional norms of elite circulation from the 18th Party Congress and partly the result of a large-scale anti-corruption campaign under the Xi leadership.

Data shows that the purges since 2023 have been more severe in both scope and number, with 55 members already purged, a figure that exceeds the total dismissals recorded across the entire 18th Congress. Given that some leaders in the “likely to remain” calculation may still exit between now and the convening of the 21st Party Congress, the 21st CC will likely see a turnover rate exceeding two-thirds (67%), making it one of the most consequential reshufflings in the post-Deng era. 

The cyclical rumour season preceding major leadership transitions remains as active as ever. With foreign China watchers having limited contact with Chinese sources and with social media’s growing ability to rapidly amplify unverified information, fact-driven empirical analysis is in greater demand. As the 21st Party Congress approaches, the proliferation of disinformation and misinterpretations may pose a significant challenge to sound judgment.

In an environment often characterised by political opacity, empirical research remains the most effective tool for observing Chinese politics. However obscure the CCP leadership transition may appear from the outside, most changes are both measurable and predictable. Observations at this stage indicate that a large-scale leadership reshuffling is expected at the 21st Party Congress. 

Upcoming institutional milestones including the formation of the 21st Party Congress Preparatory Group, provincial-ministerial leadership reshuffles, resolutions of major anti-corruption cases, and anticipated reorganisation of the CMC, will yield empirically verifiable indicators for analysts. When contextualised alongside decisions announced in the 20th CC’s concluding plenums, these developments will furnish observers with a framework to distinguish systemic patterns from transient political noise.
