This chapter examines the most recent changes in China's policy towards the South Chins Sea (SCS) since 2013. On January 22, 2013, the Philippines initiated the SCS Arbitration case against China. It assesses China's policy practices of maritime governance and finds that the trend of consolidating jurisdiction through enhancing governance continued, with even greater efforts. It summarizes the developments of China's SCS policy in the post-2013 period and analyzes the concrete roles of the law of the sea regime in shaping the latest contours of China's SCS policy. In the post-2013 period, China's marine governance in the SCS continued to concentrate on two tasks: transferring the practices of international marine governance into its maritime legislation and governance in the SCS; and using marine governance practices to consolidate its sovereignty and jurisdiction over the claimed waters in the SCS.
