Moscow and Beijing fly their 11th joint air patrol, drawing Seoul into a wider signalling contest

Desk note: Monexus treated the 27 June patrol as a recurring signalling event rather than a standalone crisis. Wire reporting in Seoul leaned into the incursion framing; Chinese and Russian statements emphasised routine. Both framings are reproduced above and the structural reading, institutionalised cadence as a strategic product, is offered as the synthesis.
