Con todo, la presencia china al este de Taiwán ya había comenzado a principios de mayo y se mantuvo «constante» incluso tras la conclusión de la citada «operación especial» de Pekín, asegura Jason Wang, director de operaciones de ingeniSPACE, una firma de inteligencia geoespacial con sede en Silicon Valley.

Un análisis elaborado por esta empresa a partir de datos satelitales y de los sistemas de identificación automática (AIS) revela que, entre el 1 y el 8 de junio, los buques de la CCG navegaron por una amplia zona al este de Taiwán, desde las inmediaciones de su costa oriental hasta bien entrada la zona económica exclusiva reclamada por Taipéi.

It was revealed on the 28th that multiple China Coast Guard (CCG) vessels began making routine voyages in Japan's Exclusive Economic Zone (EEZ) south of Yonaguni Island, Okinawa Prefecture, in June, and commenced escorting Chinese marine research vessels and government ships. The Japanese government has also confirmed this activity. Although China has long claimed "jurisdiction" over this area—located east of Taiwan—the actual exercise of such authority is highly unusual. This move clearly signals opposition to the fact that Japan and the Philippines have designated this same area as a subject for maritime boundary delimitation negotiations.

中国海警局の複数の艦船が6月、沖縄県・与那国島南方の日本の排他的経済水域（EEZ）での航行を常態化させ、中国の海洋調査船と公船の護衛を始めたことが28日、分かった。日本政府もこの動きを確認した。この海域は台湾の東方で、中国は「管轄権」を主張してきたが、実際に権限を行使するのは極めて異例だ。同じ海域を日本とフィリピンが境界画定交渉の対象としたのに対抗する姿勢を鮮明にした。

According to AIS data, the research vessel Zhong Shan Da Xue sailed through the South China Sea from May to June 2025. However, Sun Yat-sen University declared that the vessel was active in the South China Sea in August 2025, which contradicts the AIS data. The announcement stated that Sun Yat-sen University had conducted sea-trials of Haiqin, a remotely operated vehicle (ROV) capable of operating at depths of up to 6,000 meters, and that Zhong Shan Da Xue had deployed the Haidou-1 autonomous underwater vehicle (AUV) at the same time. This marked the first scientific survey conducted by coordinating two different unmanned vehicles via a single support ship¹⁴.

Communist Party Oath on a PAF-MM Ship: “我志愿加入中国共产党，调护觉的纲领，遵守党的章理，履行美员火分。执行党的决定，严守党的经售，影9金 的秘密，对觉出说，现败工作为去产主火奋斗終身，随财准過方党和人民間性一切，永不频算，

“China prefers ‘invisible hybrid warfare’ (隐形混合战) over kinetic warfare.  Covert irregular warfare enables China the means to quietly overwhelm its targets not only physically but economically and politically as well – all without firing a shot.  The use of civilian fishing vessels not only provide plausible deniability but legitimizes China’s claims and salami-slicing tactics as lawful and just.”

For over a decade, the Chinese Communist Party has deployed “fishing fleets” and coast guard vessels as tools of coercion, blurring the line between civilian and military activity to expand its control across the Indo-Pacific. In the East China Sea, more than 600 Chinese vessels formed coordinated lines for hours at a time. In the Yellow Sea, China installed large aquaculture cages and a network of surveillance buoys in contested waters with South Korea. And in the South China Sea, China has surged coast guard patrols around Scarborough Shoal while constructing new artificial outposts at reefs near Vietnam complete with jetties, helipads, and potential runways. This is not routine commerce, it's gray zone warfare designed to intimidate U.S. allies, restrict access to international waters, and normalize China’s unlawful territorial claims. The U.S. and its partners must respond with urgency, strengthening maritime domain awareness, supporting frontline allies, and defending freedom of navigation.
