If large-scale, coordinated fishing vessel formations near Japan’s EEZ persist and draw closer to the Senkaku/Diaoyu Islands, then the normalization of gray zone coercion by non-military means becomes harder to distinguish from de facto maritime assertion.
Bottom Line Up Front: The repeated formation of up to 2,000 Chinese fishing vessels near Japan’s EEZ constitutes a strategic escalation by Beijing, leveraging maritime militia tactics to assert dominance in the East China Sea without direct military confrontation, posing a serious threat to regional stability and Japanese sovereignty [1].
Threat Identification: China is employing large-scale, coordinated fishing fleets as part of its 'gray zone' strategy—using civilian-appearing vessels to conduct surveillance, assert maritime claims, and pressure adversaries below the threshold of armed conflict. These formations, observed twice recently, suggest rehearsed swarm tactics potentially supporting future coercion around the Senkaku/Diaoyu Islands [1].
Probability Assessment: High probability (>80%) of recurring formations throughout 2026–2027. Such operations are likely to increase in frequency and proximity to Japanese-administered waters, especially during periods of heightened diplomatic tension or joint U.S.-Japan exercises [1].
Impact Analysis: The deployment undermines Japan’s maritime sovereignty, risks accidental clashes, complicates naval operations, and could normalize Chinese control over contested waters. If unchecked, this tactic may embolden similar actions in the South China Sea and against other U.S. allies [1].
Recommended Actions: 1) Enhance real-time maritime domain awareness through satellite and AI-driven vessel tracking; 2) Publicly declassify and disseminate evidence of militia coordination; 3) Strengthen bilateral and multilateral patrols with U.S., Philippines, and Australia; 4) Impose targeted sanctions on entities supporting militia logistics; 5) Develop legal and diplomatic counter-narratives to delegitimize 'fishing' cover for coercion [1].
Confidence Matrix: Threat Identification – High confidence; Probability Assessment – Moderate to High confidence; Impact Analysis – High confidence; Recommended Actions – High confidence in feasibility, Moderate in immediate adoption.
