Taiwan's defense ministry logged 21 People's Liberation Army aircraft and 15 vessels operating around the island over the Sunday reporting window, a day after a separate count of 17 Chinese ships in the strait itself, and the split matters more than the total. The strait count is the familiar pressure gauge Taipei's ministry has published for years; the east-of-Taiwan count, tracking the Pacific-facing coast where amphibious-landing scenarios have never been the operative worry, is the newer instrument, and it is the one that lines up with what the PLA Navy's Southern and Eastern Theater Commands would need in place well before any landing craft mattered.

The distinction is not academic to the desks that price sovereign and shipping risk off it. A strait squeeze is a tariff on trade passing between China and Taiwan; a blockade staged from the Pacific side is a tariff on everything moving through Kaohsiung and the eastern approaches regardless of origin, which is why Lloyd's-linked war-risk underwriters and MSCI's Taiwan-weighting committee watch ship-count geography, not ship-count totals. Or, more precisely, they watch which coast the count comes from, because that is the variable that tells an underwriter whether the exposure is bilateral or global. Taiwan's ministry has not reclassified its Sunday releases to separate the two coasts formally, but the raw numbers already show Beijing building the option on the side of the island where a blockade, not a landing, actually has to start.
