The Chinese Communist Party expelled two senior military officials this week over alleged corruption and disloyalty, according to AP reporting, thinning Xi Jinping's Central Military Commission to two members ahead of his September 24 meeting with Donald Trump. Xi has now removed rivals from his own command structure twice inside a month, once in late August and again days before boarding the plane to Washington. A leader who purges his own general staff before a summit is not projecting strength to the room he is about to enter. He is clearing the room behind him first.

The sequencing matters because Xi arrives at the White House this week to press Trump on the frozen 14 billion dollar Taiwan arms sale, a threat Beijing raised September 19 and has not withdrawn. A commander who trusted his military bench would not need to gut it on the eve of his highest-stakes meeting with an American president in years. Xi is walking into that room with a smaller, more loyal, less experienced command tier than he had a month ago. If the purge reflects genuine threat rather than manufactured discipline, Xi negotiates from a domestic position weaker than his Taiwan rhetoric this week suggests.
