Zhang Youxia was not some peripheral figure. He was the second-ranking member of China's Central Military Commission, long considered Xi Jinping's closest ally in uniform. Liu Zhenli was the chief of staff of the CMC's Joint Staff Department. Both are now expelled from the Communist Party on charges of corruption, forming cliques, and disloyalty. No specific crimes have been named. The charges follow a now-familiar template: "seriously violated political discipline and political rules, formed cliques and factions, and were disloyal and dishonest to the party." This language is boilerplate in Chinese anti-corruption proceedings, but the targets are anything but routine. Zhang's removal means Xi has purged the person who was functionally his own military deputy. The CMC, China's supreme military command body, formerly had seven members. It now has two active members, one of whom is Xi himself as chairman. In June 2024, Defence Minister Li Shangfu and his predecessor were expelled. More than a year later, eight additional senior military and party officials were dismissed. The military brass has been hollowed out at an extraordinary rate. The timing carries diplomatic weight. The announcement lands days before Xi is set to meet US President Donald Trump in Washington, and weeks before a key Communist Party assembly on internal governance. Announcing a purge of this magnitude before a summit is not accidental — it signals to domestic audiences that Xi's authority is absolute, and to foreign counterparts that he alone speaks for China's military. The anti-corruption campaign is now among the largest in modern Chinese history, with thousands of officials purged and millions within the bureaucracy investigated. What began under Xi's first term as a tool to remove political rivals has become a permanent feature of governance — a rolling loyalty audit that reaches every institutional layer. The structural question is whether this level of institutional churn creates fragility. A military command structure that cycles through leadership at this pace risks losing institutional knowledge, operational continuity, and the kind of honest internal dissent that prevents catastrophic errors. The officers who remain know one thing clearly: survival depends on perceived loyalty, not on delivering uncomfortable truths. What Xi gains in personal control, the PLA may lose in competence and cohesion. The 20-year trajectory of this pattern is a military optimized for political compliance rather than warfighting capability — a distinction that matters enormously in a Taiwan Strait scenario or any real confrontation.
