China sent a wave of warplanes and warships around Taiwan, keeping military pressure on the island high.

• Sixteen Chinese aircraft flew out over the sea starting mid-morning, and 11 of them crossed the unofficial line down the middle of the Taiwan Strait.
• The planes pushed into airspace off Taiwan's north, center, and east, flying alongside Chinese navy ships.
• Beijing called it a "joint combat readiness patrol," which Taiwan's defense ministry rejects as cover for harassment.
• Taiwan tracked the movements and sent up its own planes and ships, with land-based missile units on alert.

Outlook: These patrols have become routine, so more incursions are likely in the coming days.
