Beijing told Tokyo yesterday it would cancel the planned summit between Xi Jinping and US President Donald Trump if Washington approves new arms sales to Taiwan, according to Japanese media cited by the Taipei Times. The warning did not arrive alone. Taiwan's defense ministry tracked seven Chinese warships and five aircraft operating near the island in the same 24-hour window, and Taiwan's military ran missile drills near Pingtung. The Institute for the Study of War logged the summit threat as part of a broader pressure campaign, not an isolated diplomatic cable. Beijing has not named which arms package would trigger the cancellation, only that one exists.

The structure is a trade, not a threat. Beijing is telling Washington the summit is a deliverable it controls, and the price is a freeze on a specific category of US decision-making that has nothing to do with the summit's stated agenda. That is a different animal from the sanctions and overflights Beijing used after Nancy Pelosi's 2022 visit, which punished a completed act. This is pre-emptive: the arms sales have not been approved, and Beijing is pricing them before Washington moves. If Trump approves the sales anyway, Beijing loses a summit it wanted enough to route the warning through Tokyo rather than deliver it directly. If Washington shelves the sales to save the summit, Taiwan's next procurement request will not be negotiated with Washington. It will be negotiated with Beijing's veto already priced in.
