Creeping Sovereignty: What is China Building in the Yellow Sea (West Sea?) | Explainer Video
What is China building in the area in and around the Korea-China Provisional Measures Zone (PMZ) in the Yellow Sea (West Sea)? Is it really only for fishing, or are there dual-nature capabilities that we should worry about? What do we really know about the 13 buoys, the 2 aquaculture cages (Shen Lan 1 & Shen Lan 2), and the integrated management platform (Atlantic Amsterdam) that China has placed in the area?
CSIS' Victor Cha believes China's structures in the Yellow Sea and its harassment of South Korean vessels resemble "creeping sovereignty" grey zone tactics that Beijing employed in the South and East China Seas. Watch now for policy recommendations on how the U.S. and Korea should respond to China.
Victor Cha is President of the Geopolitics and Foreign Policy Department and Korea Chair at the Center for Strategic and International Studies.
