Beijing has removed Zhang Youxia and Liu Zhenli from the Central Military Commission, the body that commands the People's Liberation Army under Xi Jinping. Both men were placed under investigation earlier this year for what state media termed serious disciplinary violations. Zhang held the vice chairmanship, the second-ranking uniformed post on the seven-member commission and one Xi has now emptied twice in three years.

A defense minister can be replaced without breaking a chain of command. A vice chairman cannot; the post exists to hold operational authority when the chairman is absent, and Xi has now pulled the man who held it while Chinese naval activity around Taiwan sits at a recorded high of 244 vessels in July. The removal lands before any war-fighting contingency, not after one. What resolves the read: whether Xi elevates a successor from the Rocket Force or the Eastern Theater Command, the two power centers most tied to Taiwan planning, by the commission's next full session.
