Ocean is a single body and it needs a comprehensive management. The Korean ocean governing regime has undergone four stages of evolution, which include a concentrated governing regime featured by the Korean Maritime Affairs Bureau in early days, then a disintegrated governing regime, later a concentrated governing regime featured by the Korean Ministry of Maritime Affairs and Fisheries, and currently a concentrated governing regime featured by the Korean Ministry of Land, Transport and Maritime Affairs. The current ocean governing regime of China is a disintegrated one which causes problems such as overlapping functions of maritime related government agencies, waste of administrative resources, and low governing efficiency.

This article presents the evolution of Korean ocean governing regime, analyzes the advantages of concentrated governing regime, and discusses what experience China can draw from Korea to improve the ocean governing regime of China.
