China’s military is facing a major upheaval as General Zhang Youxia, one of the top officers in the People’s Liberation Army (PLA), is under investigation. The vice chairman of the Central Military Commission (CMC) and China’s highest-ranking uniformed officer, Zhang, is accused of corruption and allegedly leaking sensitive nuclear weapons information to the United States, according to The Wall Street Journal.

The investigation also involves General Liu Zhenli, chief of staff of the CMC’s Joint Staff Department. The developments have fueled speculation about internal power struggles and Xi Jinping’s efforts to consolidate control over the military ahead of the 2027 Communist Party Congress.

Who is Zhang Youxia?

Zhang Youxia, vice-chairman of the Central Military Commission (CMC) and the second-most senior officer under President Xi, has long been considered a close ally of Xi. A veteran of border conflicts with Vietnam in 1979 and 1984, Zhang is credited with modernising the PLA and bringing professional expertise to the military hierarchy.

Reports note that Zhang, expected to retire in 2022, was retained for a third term to provide continuity and serve as a trusted military adviser. His removal marks only the second time a sitting general on the CMC has been purged since the Cultural Revolution (1966–76).

Allegations against Zhang

China’s defence ministry announced that Zhang is being investigated for “suspected serious violations of discipline and law,” without elaborating. The PLA Daily accused him and fellow general Liu Zhenli of undermining the “chairman responsibility system” and fostering political and corruption problems that threatened the Communist Party’s absolute control over the military.

The Wall Street Journal reported that Zhang allegedly leaked sensitive information about China’s nuclear weapons programme to the United States and accepted bribes in exchange for promotions, including elevating a former defence minister. While the authenticity of these claims has not been independently verified, the accusations highlight the severity of the investigation.

Political and strategic implications

Analysts say Zhang’s public investigation signals that Xi is prioritising loyalty over professional relationships, even among his closest military allies. “Xi has completed one of the biggest purges of China’s military leadership in the history of the People’s Republic,” said Neil Thomas, a fellow at the Asia Society Policy Institute’s Center for China Analysis.

The purge has thinned the PLA’s senior ranks, raising questions about morale, procurement, and the pace of military reforms. It also underscores that no official is immune from scrutiny, sending a warning to other senior officers.

Broader anti-corruption campaign

Zhang’s investigation is part of Xi Jinping’s broader anti-corruption drive, which has disciplined over 200,000 officials since 2012. The crackdown previously targeted the elite Rocket Force and other top military bodies. Analysts say the campaign is designed both to eliminate rival power bases and to ensure loyalty to Xi, while modernising the PLA ahead of strategic objectives for 2035 and 2049.

Regional and global repercussions

Foreign governments and Taiwan’s leadership are closely monitoring the developments, with concerns that leadership instability could temper China’s near-term assertiveness in the East China Sea, South China Sea, and around Taiwan. Experts note that daily military operations are expected to continue, but the purge reflects Xi’s effort to address criticism that previous crackdowns were selective.

Singapore-based security scholar James Char said, “Xi has been tapping second-line PLA officers to fill those roles vacated by predecessors, on an interim basis in most cases. China’s military modernisers continue to pursue Xi’s goals of completing PLA modernisation by 2035 and achieving world-class status by 2049.”

A clear signal of Xi’s control

Zhang’s fall, following the expulsion of former CMC vice-chair He Weidong and several top generals over the past year, highlights Xi’s unflinching approach to consolidating power in China’s armed forces. Analysts suggest the purge is as much about political loyalty as anti-corruption, reinforcing the Communist Party’s principle that the military remains under the party, and Xi’s absolute control.
