發生了什麼
解放軍東部戰區於2025年12月29日上午宣布代號「正義使命-2025」的聯合演習，動用陸軍、海軍、空軍與火箭軍部隊，在臺灣周邊海空域進行。這是自2022年8月以來在該島周邊的第八次大型演習，持續至東部戰區於12月31日深夜宣布結束，前兩天活動最為密集。臺灣國防部報告第一天偵獲89架航空器與28艘艦船 — 其中13艘為中國海警而非海軍 — 第二天偵獲71架航空器及另外15艘海警船；12月29日是有紀錄以來單日進入防空識別區架次第二多的一天。宣布的管制區部分透過東部戰區的航行警告公布，部分透過中華人民共和國海事局公布，另有一個區域僅以無線電宣布。各方說法對總數不一：臺灣國防部指出七個劃設區域，另有一份彙整則計為八個。
This is the reference point against which every later statement about the 2026 activity baseline is measured, and three things about it are load-bearing. First, the Eastern Theater Command's own stated objectives included "blockading key ports and territory" alongside combat-readiness patrols and deterrence of outside intervention — Vigil records that as declared exercise language, not as evidence that any blockade occurred or was attempted, and no interference with commercial shipping was reported. Second, the announced areas sat closer to Taiwan than in previous exercises, with several overlapping waters Taiwan claims as territorial sea; no PRC vessel entered that territorial sea, and roughly ten rockets are reported to have impacted within the contiguous zone twelve to twenty-four nautical miles out — the first such firings since 2022. Declared zone geometry, actual vessel entry and munition impact are three different facts and secondary reporting routinely collapses them. Third, coast guard vessels operated inside a military joint exercise, which is the clearest documented instance of the law-enforcement instrument and the military one being used together.
