Taiwan's defense ministry logged 27 PLA aircraft and 11 vessels operating around the island in the 24 hours to Friday, and the geography is the story: sorties east of Taiwan, not concentrated in the southwest air defense identification zone that has anchored PLA activity since 2020. The Global Taiwan Institute flagged the same eastward shift this week. Taiwan's east coast holds the mountain-shielded missile and radar sites Taipei has spent two decades building precisely because the terrain blocks a first strike from the west. An eastern approach does not threaten those sites today. It rehearses reaching them.

Beijing paired the flights with a warning through Global Times naming Taiwan independence advocates as targets, language that tracks the extraterritorial jurisdiction law Beijing activated against individual Taiwanese this month rather than the broad coercion rhetoric of prior years. The east-coast sorties, read against a law built for named individuals over blockade theater, mark a shift from demonstrating capability against the island to mapping the approach that would remove its second-strike option. The next signal to watch is whether the People's Liberation Army Eastern Theater Command holds that eastern posture through August or reverts to the southwest ADIZ pattern once the current drill window closes.
