The Global Taiwan Institute recorded an uptick in People's Liberation Army Navy activity east of Taiwan this week, the axis Taipei's Ministry of National Defense has flagged since 2024 as the approach route for a blockade rehearsal. The increase sits alongside the pattern this desk reported on July 25: PLA aircraft sorties near Taiwan fell to a three-year low even as coercion intensified elsewhere. Beijing is not choosing between air and sea pressure. It is rotating which instrument carries the message, and this week the message moved to ships.

A blockade drill built on naval assets east of the island, rather than air incursions into Taiwan's air defense identification zone, changes what Taipei has to track and what Washington has to explain to Congress. Sorties are counted daily and published; naval deployments east of Taiwan, outside the median-line incidents that get same-day reporting, are harder to verify in real time. The Ministry of National Defense's next monthly PLA activity summary, due the first week of August, will show whether the naval increase holds or was a single exercise window.
