China kept up pressure around Taiwan with another large air and sea push, a negative sign for regional stability.

• Taiwan tracked 18 Chinese military aircraft, 8 navy ships, and 1 government vessel near the island in a single day.
• Most of the planes crossed the unofficial median line in the Taiwan Strait, entering airspace to the north, center, southwest, and east.
• Fighters, bombers, surveillance planes, helicopters, and drones all took part, paired with warships in what Beijing calls a "joint combat readiness patrol."
• Taiwan's military says it monitored the activity with its own planes, ships, and shore-based missile systems.

Outlook: These near-daily incursions look set to continue, keeping tension high around the strait without an immediate flashpoint.
