China's Gray-Zone Warfare at Sea and Counter-Strategies for the First Island Chain

This analysis examines China's use of irregular, or gray-zone, warfare tactics to exert pressure on Taiwan and neighboring regions without triggering open conflict. By exploiting bureaucratic gaps in maritime law enforcement and national defense mandates, Beijing employs dual-use forces, including the People's Armed Forces Maritime Militia and commercial vessels, to disrupt critical infrastructure like submarine communication cables. These actions create jurisdictional confusion among coast guards and navies, allowing China to achieve strategic gains while avoiding kinetic escalation. The article argues that traditional whole-of-government responses are insufficient against these methods. Instead, it proposes that nations within the First Island Chain, such as Japan, the Philippines, and Taiwan, must enhance regional cooperation through shared intelligence and transparency. Leveraging existing technologies like commercial satellite constellations, synthetic aperture radar, and distributed acoustic sensing can provide cost-effective deterrence. The author emphasizes that integrating command, control, and surveillance systems across borders is essential for maintaining maritime domain awareness and countering Beijing's revisionist expansionism, ultimately preventing war through preparedness and collective defense capabilities.
