MEL GURTOV – The long-running, multi-party dispute over control of islets in the South China Sea (SCS) is worsening both in rhetoric and provocative activity. Meeting in late May at the Shangri-La Dialogue on regional security, U.S. and Chinese defense officials sparred over responsibility for the increased tension, though they stopped short of issuing threats. In fact, all sides to the dispute say they want to avoid violence, prefer a diplomatic resolution, and support freedom of navigation.
