China runs first coordinated maritime law-enforcement operation east of Taiwan, drawing US and European condemnation
PRC coast guard vessels asserted jurisdiction in the Pacific waters beyond Taiwan's eastern coastline, interfering with commercial ships and triggering joint statements from the AIT, UK, France and Germany
Summary
China's Ministry of Transport ordered a "special maritime law enforcement operation" from June 6-10 in waters east of Taiwan, outside the Taiwan Strait and in the Pacific approaches to Taiwan's eastern coast. PRC coast guard vessels interfered with Taiwanese commercial ships and asserted jurisdictional authority in an area Taiwan, the United States, and international maritime law regard as open sea. The operation was triggered, according to analysis by Focus Taiwan and Bloomberg, by ongoing Japan-Philippines EEZ delimitation talks that could implicitly reduce China's claimed maritime space. The American Institute in Taiwan, alongside British, French, and German representative offices in Taipei, issued a joint condemnation. Taiwan's Coast Guard Administration rejected the PRC assertion of rights, stating Beijing has no sovereignty in those waters. The episode continued generating diplomatic statements through June 24-26.
The split
Taipei and Washington framed the operation as escalatory "salami-slicing," establishing jurisdiction precedents without a direct military confrontation. Beijing's Global Times insisted the operation was routine and that foreign condemnation was politicised interference. Japan's Asahi Shimbun covered the story with concern about PRC encirclement of the East China Sea from a new angle. The Philippines, despite its own South China Sea disputes with China, did not join the joint condemnation, reflecting Manila's careful balancing act. Singapore's Straits Times covered it as a regional stability concern without assigning blame explicitly.
By the numbers
- 5 days, duration of the June 6-10 PRC "special maritime law enforcement operation"
- 4 nations' offices, AIT plus UK, France, Germany, that issued joint condemnation
- 1st time, China has formally asserted enforcement jurisdiction east of Taiwan in the Pacific
- 2, Taiwan subsea cables traversing waters east of the island vulnerable to disruption
Why it matters
Eastern Taiwan is the island's strategic rear. The subsea cables linking Taiwan to Japan and the United States pass through these waters, and Taiwan's air force and naval bases along the east coast are the island's primary second-strike assets. China establishing routine patrol presence east of Taiwan converts a previously uncontested sanctuary into a contested zone, potentially degrading both Taiwan's defence depth and the reliability of undersea data infrastructure. The EEZ delimitation trigger also signals Beijing is using commercial maritime law arguments as a vector to extend jurisdictional precedents.
What to watch
- Whether PRC coast guard vessels resume operations east of Taiwan after the June 6-10 window
- Japan-Philippines EEZ delimitation talks timeline and whether the talks are affected
- Taiwan's Ministry of National Defence review of drone training for reservists, announced in the same week
- US Navy freedom-of-navigation operations in the eastern Pacific approaches to Taiwan
