Beijing has launched an investigation into two of China’s highest-ranking military officials, marking the latest phase in President Xi Jinping’s campaign to consolidate control over the People’s Liberation Army (PLA). The Ministry of Defense announced that Central Military Commission (CMC) Vice Chairman Zhang Youxia and Joint Staff Chief Liu Zhenli are under investigation for “serious disciplinary and legal violations.” Their removal leaves the CMC with its fewest members in history, now comprising only Xi Jinping and Zhang Shengmin, the head of the military’s anti-corruption body.

The CMC is China’s top military decision-making body, responsible for strategy and operations. Analysts note that the probe underscores Xi’s tightening grip on the armed forces, continuing a years-long effort to ensure political loyalty within the PLA. While “disciplinary violations” often refer to corruption, such investigations have historically been used to eliminate political rivals. Researcher Tristan Tang of the Pacific Forum said the move highlights Xi’s strength and may also relate to inefficiencies in defense resource management and combat readiness.

The investigation could last months or years, with most accused officials typically detained, convicted, and stripped of their positions and party membership.
