The South China Sea dispute has gained increasing prominence in recent years, with China being especially aggressive with its claims. Today, we speak to Dr Collin Koh, Research Fellow at the S. Rajaratnam School of International Studies, on some basic questions about the dispute. We discuss its history, the significance of the nine-dash line, the actions of various claimant states as well as the United States, ASEAN’s lack of unity, the feasibility of a code of conduct, the role of Chinese fishing fleets, and the stakes for a non-claimant state like Singapore.
