## Summary

中国交通部は2026年6月6日から10日にかけて、台湾東方の太平洋海域、すなわち台湾海峡の外側で「特別海上法執行作戦」を発令した。中国海警の艦艇は台湾の商船に干渉し、台湾・米国・国際海洋法がいずれも公海と見なす海域での管轄権を主張した。在台湾米国協会（AIT）は在台英国・フランス・ドイツ代表機関とともに共同非難声明を発出。台湾海巡署はこの主張を拒否し、中国には同海域に主権的権利がないと明言した。この問題は6月24〜26日も外交声明を生み続けた。

## Why it matters

台湾東方海域は島の戦略的後方にあたる。台湾と日本・米国を結ぶ[海底ケーブル](/ja/n/taiwan-matsu-cable-cut-2026)がこの海域を通過しており、東岸の空軍・海軍基地は島の主要な第二撃戦力でもある。中国が台湾東方に常態的な哨戒プレゼンスを確立すれば、従来争いのなかった聖域が係争地帯に変わり、台湾の防衛縦深と海底データインフラの信頼性が低下しかねない。EEZ画定問題を口実にしていることは、北京が商業海洋法の論拠を管轄権先例の拡大に活用していることを示している。

## What to watch

- 6月6〜10日の期間後に中国海警が台湾東方での活動を再開するか
- 日比EEZ画定交渉の行方とその変化
- 台湾国防部による予備役のドローン訓練の見直し状況

### Taipei establishment, sovereignty framing
- **Taiwan News / Focus Taiwan** (Taiwan, zh) — Focus Taiwan reported the PRC's Ministry of Transport ordered a 'special maritime law enforcement operation' from June 6-10 in waters east of Taiwan, described as triggered by Japan-Philippines EEZ delimitation talks. Taiwan's Coast Guard Administration said Beijing 'has no sovereign rights' in the area and that PRC coast guard vessels interfered with Taiwanese commercial shipping.

### US financial/geopolitical
- **Bloomberg** (United States, en) — Bloomberg connected the eastern-Pacific operation to Japan-Philippines EEZ talks, framing it as China using maritime enforcement to establish a precedent of jurisdiction before a boundary delimitation that might reduce Beijing's claimed maritime space. Sources in the US government described it as 'precisely the kind of salami-slicing we've been warning about.'

### Chinese nationalist state media
- **Global Times** (China, zh) — Global Times described the operation as a routine enforcement of China's 'legitimate maritime jurisdiction rights' and dismissed AIT and European condemnation as 'interference in China's internal affairs and an attempt to weaponise the Taiwan question against China's core interests.'
  > "此次海上执法行动是对中国合法海洋管辖权的例行行使，外方批评是干涉中国内政。 (This maritime enforcement operation is a routine exercise of China's legitimate maritime jurisdiction rights; foreign criticism is interference in China's internal affairs.)"
