Asia Martime Transparency Initiative – China’s deployments of buoys in the Yellow Sea add yet another layer to its approach toward managing disputes with South Korea while furthering its own maritime interests. Like many of China’s maritime activities, the buoys accomplish several things simultaneously: they increase China’s monitoring and sensing capabilities in an important maritime area; they assert control over a less sensitive but still disputed portion of overlapping maritime claims; and, importantly in the Yellow Sea context, they test South Korean reactions to inform future deployments.
