China Intensifies Maritime Pressure on Taiwan Amid Japan-Philippines EEZ Talks
6/20/2026, 7:17:00 AM
Escalation of Chinese Maritime Operations East of Taiwan
Since early May 2024, Chinese Coast Guard vessels and research ships have entered Taiwan-controlled waters east of the island, the Pratas Islands, Itu Aba (Taiping) Island and Kinmen County. Notable incidents include the research vessel Tongji circling Taiwan on May 7 and May 14, and the oceanographic vessel Xiangyanghong 22 conducting a three-day survey from June 18-20. Taiwan’s Coast Guard Administration (CGA) has responded with a “shadowing and monitoring” posture, deploying a matching patrol ship for each Chinese vessel.
Background & Context
Beijing’s actions are part of a broader “gray-zone” strategy that blends law-enforcement pretenses with hybrid warfare. The moves follow the Japan-Philippines announcement on May 28 to negotiate overlapping exclusive economic zones (EEZs) east of Taiwan, a development Beijing has framed as a pretext for heightened patrols. Taiwan views the talks as legally non-binding on third parties and maintains separate fisheries agreements with both Japan and the Philippines.

Timeline
- May 7 & 14, 2024 – Chinese vessel Tongji circles Taiwan, deploys monitoring equipment.
- May 28, 2024 – Japan and the Philippines announce EEZ delimitation talks.
- June 1, 2024 – Chinese Coast Guard begins law-enforcement patrols in waters east of Taiwan.
- June 18, 2024 – President Lai holds a press conference on Chinese activities.
- June 18-20, 2024 – Xiangyanghong 22 conducts a marine survey east of Taiwan.
- June 20, 2024 – Deputy Minister Sung outlines the CGA’s “shadowing and monitoring” strategy.
Data & Statistics
- Xiangyanghong 22: 3,000-tonne class research vessel launched 2018.
- CGA reports deploying an equal number of patrol ships to Chinese vessels on a rotating basis.
- Chinese vessels observed operating under the “three noes” (no name, no registration, no flag) pattern.
Why It Matters
The intensified presence turns Taiwan’s eastern waters from a “rear area” into a potential front line, raising the risk of miscalculation between the People’s Republic of China and Taiwan. The activity also tests the legal limits of “gray-zone” enforcement and could reshape regional security dynamics involving Japan, the Philippines, and the United States.
Official Statements & Responses
Taiwanese officials stress that China has no legal jurisdiction over the contested waters and that the CGA’s shadowing approach aims to prevent unlawful incursions without using force. President Lai framed China as the “greatest risk and threat” to neighboring states, urging collective Indo-Pacific action. Ho Cheng-hui warned that Beijing is weaponizing sovereignty disputes to exploit loopholes in international law.
China’s State Council spokesperson Chen Binhua asserted that the patrols are lawful, defending China’s EEZ and continental-shelf rights and condemning Japan-Philippines talks as “illegal and invalid.” The Ministry of Natural Resources described the Xiangyanghong 22 mission as a scientific survey to support marine ecological conservation.
Criticism & Opposition
Taiwan’s opposition parties labeled President Lai’s response “soft,” fearing erosion of sovereignty. KMT legislator Ko Chih-en warned that exclusion from the Japan-Philippines talks could jeopardize Taiwanese fishing rights. Conversely, the Chinese government accused the Democratic Progressive Party of acting “subservient” to foreign pressure.
Conflicting Reports & Gaps
- Taiwan maintains that the Japan-Philippines EEZ talks cannot affect its rights under the Vienna Convention, while China claims the talks impinge on its jurisdiction.
- Chinese sources present the Xiangyanghong 22 operation as a scientific survey, whereas Taiwanese officials describe it as a provocative assertion of sovereignty.
- Precise numbers of Chinese vessels operating daily remain unspecified, creating uncertainty about the scale of the “shadowing” response.
Verbatim Quotes
- “The People’s Republic of China has never exercised sovereignty over Taiwan and therefore has no jurisdiction over waters east of Taiwan, Sung said.” — Sung Chen-en, Deputy Minister, Ocean Affairs Council
- “The only and greatest risk and threat to neighboring countries is China, which arbitrarily enters the exclusive economic zones [of Japan, Taiwan, and the Philippines] under the pretext of law enforcement, while in reality pursuing expansion.” — President Lai Ching-te
- “There is only one China in the world, and Taiwan is part of China.” — Chen Binhua, Spokesperson, State Council Taiwan Affairs Office

What’s Next
Taiwan plans to maintain its one-for-one shadowing patrols, expand joint maritime law-enforcement drills with Japan and the Philippines, and pursue diplomatic channels to contest China’s gray-zone activities in international forums. Beijing has signaled continued patrols, suggesting the maritime standoff will persist throughout the coming months.
