Taiwan calls China’s military shakeup “abnormal,” steps up surveillance

Taiwan’s government has formally described the recent leadership changes within China’s military command as “abnormal” and linked them to Beijing’s longstanding position of refusing to renounce force over the Taiwan Strait. On January 26, 2026, Taiwan’s Defence Minister Wellington Koo confirmed that the Ministry of National Defense is tracking shifts in the People’s Liberation Army’s upper leadership, following the announcement that General Zhang Youxia and Lieutenant General Liu Zhenli are under investigation by China’s Ministry of National Defense.

Zhang Youxia, who served as vice-chairman of the Central Military Commission of the People’s Republic of China and was widely regarded as President Xi Jinping’s most trusted military ally, had not been seen in public since November 2025. Liu Zhenli, as chief of staff of the Joint Staff Department, was operationally responsible for daily command oversight and coordination.

Minister Koo clarified that Taiwan was not drawing conclusions based on a single reshuffle, but said the investigations were being watched in the context of China’s sustained military pressure. He indicated that Taiwan’s military would continue to rely on a comprehensive set of intelligence, surveillance, and reconnaissance tools, and would collaborate with partners to interpret shifts in Beijing’s political-military structure.

What is the strategic importance of General Zhang Youxia and Liu Zhenli in China’s military command?

General Zhang Youxia’s removal marks a significant moment in the military hierarchy of the People’s Republic of China. Zhang, a veteran of the 1979 Sino-Vietnamese war, held one of the highest ranks in China’s armed forces and was also a member of the Politburo of the Communist Party of China. His role as vice-chairman of the Central Military Commission placed him second only to Xi Jinping in the Chinese military command structure.

Lieutenant General Liu Zhenli, by heading the Joint Staff Department, had influence over day-to-day operations, planning, and force readiness. Analysts have long considered both Zhang and Liu as central figures in the military modernization agenda promoted by Xi Jinping, especially amid China’s increased assertiveness in regional flashpoints such as the South China Sea, the East China Sea, and around Taiwan.

The nature of the accusations—formally described by the Chinese Ministry of National Defense as “serious violations of discipline and law”—echoes terminology used in previous anti-corruption purges that targeted senior officials across state and military institutions.

How does this investigation connect with Xi Jinping’s broader anti-corruption campaign in the military?

The probe into Zhang and Liu fits into a broader pattern of disciplinary purges within the People’s Liberation Army that has intensified in recent years. Since launching a sweeping anti-corruption campaign in 2012, President Xi Jinping has frequently targeted military officers and arms procurement departments. The 2023 overhaul of the PLA Rocket Force leadership had already signalled a renewed focus on internal accountability within strategic units.

In Zhang’s case, this is only the second time since the Cultural Revolution that an active vice-chairman of the Central Military Commission has faced public investigation. The fact that the probe also involves Liu Zhenli—who had oversight over the Joint Staff Department—suggests that the Central Military Commission’s internal coherence may be undergoing significant stress. Despite this, most regional security experts believe that operational continuity will be maintained, with interim officers already tapped to fill critical vacancies.

What intelligence approach is Taiwan taking to interpret the implications of Beijing’s internal shifts?

Wellington Koo confirmed that the Republic of China’s Ministry of National Defense is not viewing this leadership change in isolation. Instead, Taiwan is leveraging multiple forms of surveillance and intelligence-sharing to construct what the defence minister called an “integrated overall assessment” of China’s intentions.

This approach is shaped by Taiwan’s experience navigating a prolonged period of grey-zone conflict, wherein China has increased the frequency of air and maritime incursions into Taiwan’s air defence identification zone (ADIZ). The Ministry has indicated that the integration of non-military signals—ranging from political statements to leadership reshuffles—into its strategic assessment is key to understanding whether any shifts in military posture may follow.

Koo also reiterated that the Chinese Communist Party’s policy of refusing to renounce the use of force against Taiwan remains a constant factor. That, coupled with the institutional authority of the Central Military Commission, underscores why the integrity and leadership of that body is of high importance to Taiwan’s defence planning.

What is the wider regional context for China’s military leadership purge in early 2026?

China’s recent history of leadership reshuffles within its armed forces has unfolded amid rising tensions across the Indo-Pacific. In addition to pressure on Taiwan, the People’s Republic of China has taken assertive positions on maritime sovereignty disputes with the Philippines, Japan, and Vietnam. Chinese Coast Guard activity in the South China Sea continues to raise regional concerns, particularly in light of incidents involving contested reefs and Exclusive Economic Zones.

The leadership investigation comes only weeks after large-scale joint military exercises by the People’s Liberation Army Navy and Air Force near Taiwan. In 2025, the PLA conducted its most expansive drills around the island since the visit of then-US House Speaker Nancy Pelosi in 2022, suggesting that Beijing’s operational tempo remains elevated.

Foreign governments and analysts are watching the situation closely, particularly given Zhang Youxia’s symbolic value as a military figure tied closely to Xi Jinping’s command. The Central Military Commission plays a dual role as both a command authority and political control structure, meaning that leadership instability there carries potential implications for how power is exercised within the PLA.

Singapore-based scholar James Char, of the S. Rajaratnam School of International Studies, has noted that President Xi may be responding to perceptions that prior anti-corruption efforts were inconsistently applied. He also observed that second-tier officers are being positioned to step in, often on an acting basis, to maintain operational continuity. However, this creates a situation where military loyalty is being actively re-calibrated.

How might institutional uncertainty in China’s PLA affect Taiwan’s strategic calculations?

For Taiwan, the principal concern is not whether the leadership reshuffle creates immediate military instability in China, but whether it signals underlying shifts in political control or doctrinal focus. The Ministry of National Defense appears to be pursuing a conservative approach to interpretation—emphasizing comprehensive intelligence fusion over quick conclusions.

Taiwanese defence officials have long treated the composition and behaviour of the Central Military Commission as a critical factor in cross-Strait stability. The current development reinforces this view, particularly because of the Commission’s role in authorising and directing military exercises, grey-zone activities, and strategic signalling.

As Taiwan moves deeper into its own defence reforms—including domestic submarine production and enhanced asymmetric warfare capability—it is likely to treat such internal Chinese leadership changes as another variable to integrate into long-term deterrence planning.

Key takeaways on what this development means for Taiwan, China, and regional security

• Taiwan’s Ministry of National Defense is monitoring China’s senior military reshuffle following the investigation of General Zhang Youxia and Lieutenant General Liu Zhenli.

• The personnel actions target two of the highest-ranking officers within the Central Military Commission of the People’s Republic of China.

• Taiwan is using integrated intelligence, surveillance, and reconnaissance tools to assess Beijing’s potential intentions, without drawing conclusions from a single change.

• The investigation is part of a broader pattern of military discipline under Xi Jinping, echoing previous purges within the Rocket Force and arms procurement units.

• Regional analysts view this as a test of institutional stability within China’s military command and an important signal for Taiwan’s ongoing strategic assessment.
