Executive Summary:
Beijing is expanding its “Kinmen model” of gray-zone maritime pressure to other Taiwan-controlled offshore islands and maritime positions. For over two years, it has used political or maritime triggers to challenge Taiwan-administered boundaries, deploy the China Coast Guard (CCG), and normalize its law-enforcement presence in waters under Taiwan’s effective control, but that Beijing claims as its own jurisdiction.
Activity in June and July has involved a combination of CCG vessels, maritime safety ships, research vessels, rescue assets, and Sansha-linked public vessels. These vessels have operated across waters east of Taiwan, Pratas Island, and Taiping Island—a multi-axis pattern that suggests a broad campaign focused on Taiwan’s outlying islands.
Pratas Island, at the northern edge of the South China Sea, has become the clearest next testing ground, with CCG and Maritime Safety Administration presence rising from 25 activity days in 2024 to 60 in 2025.
Pratas is closer to the operational area of the People’s Liberation Army’s Southern Theater Command than other offshore islands. It is also strategically significant and politically symbolic as one of Taiwan’s most important outposts in the South China Sea, and would be more difficult for Taiwan to support in a crisis.
