About

PMZ and the Yellow Sea

CSIS Beyond Parallel has documented China’s construction and deployment of maritime structures—including two large aquaculture platforms (e.g., Shen Lan 1, Shen Lan 2) and a central platform called the Atlantic Amsterdam—inside and near the South Korea–China Provisional Measures Zone (PMZ) in the Yellow Sea. These structures were installed without South Korean consent and have been a point of diplomatic friction.
