The PRC Normalizes ·Law Enforcement· East of Taiwan

ISW · Institute for the Study of War ·

Executive Summary

The PRC has established a permanent "law enforcement" presence and regularized scientific surveys in waters east of Taiwan, deploying China Coast Guard (CCG) ships and civilian vessels. This continuous activity, including patrols and research, aims to assert jurisdiction and erode Taiwan's maritime rights. It is part of a multi-year strategy to encircle Taiwan and pre-position assets for potential future blockades or military operations.

Why It Matters

This document details China's escalating gray zone tactics to assert control over waters east of Taiwan, which directly impacts regional stability, international maritime law, and the potential for future conflict in a critical geopolitical flashpoint.

Key Takeaways

  • The PRC has established continuous CCG patrols and scientific surveys east of Taiwan, marking a significant escalation in its gray zone operations.
  • China is using "law enforcement" and research activities to assert jurisdiction, erode Taiwan's maritime rights, and test international responses to its expanded claims.
  • These actions are part of a long-term strategy to encircle Taiwan, control key waterways, and set conditions for potential future blockades or military action, while also challenging Japanese and Philippine sovereignty claims.

Strategic Relevance

The PRC's normalization of "law enforcement" and scientific activities east of Taiwan represents a strategic move to incrementally establish de facto control over critical maritime areas. This enhances its anti-access/area-denial capabilities, isolates Taiwan, and challenges the security architecture of the First Island Chain, directly impacting US and allied regional interests.
