The Central Military Commission's disciplinary announcement on September 22, naming two senior officers expelled for corruption and disloyalty, landed three days before Xi Jinping sat down with Donald Trump in Washington on September 24. Reuters reported the same week that the broader purge of military commanders, running since 2023 under the Commission's own inspectorate, has likely cost the People's Liberation Army some war-fighting readiness even as it tightens Xi's control over the body that would have to execute any Taiwan Strait order. China's ambassador to Washington had already told reporters on September 22 that Taiwan remains a red line Beijing will not trade away at the table, or, more precisely, a line the Foreign Ministry can hold publicly precisely because the Commission spent the same week demonstrating internally that the chain of command answers to Xi alone, not to the officer corps whose loyalty just failed two more tests.

Read against the arms sale the Pentagon has been sitting on since Beijing raised it as a threat on September 19, the sequencing matters more than either government's summit statement will. A 14 billion dollar Taiwan arms package delayed by the White House is a signal Xi's negotiators can carry into the room as leverage; two generals expelled by the Commission's own inspectorate is a signal that the room Xi negotiates from has just gotten narrower, not wider, because a purged high command cannot be the guarantor of restraint that Washington's arms-sale calculus assumes it is. The Commission's inspectorate, not the Foreign Ministry's spokesperson, is the desk that will decide whether Thursday's summit produces a deal Xi can actually enforce.
