Determination of the Name Change of the South China Sea Becoming the North Natuna Sea Reviewed from United Nations Convention on the Law of the Sea 1982

Abstract

This study analyzes the determination of the change of the name of the South China Sea to the North Natuna Sea from the perspective of international law, especially based on the United Nations Convention on the Law of the Sea (UNCLOS) 1982. The main focus is on how the regulation of maritime areas under UNCLOS 1982 and the Indonesian government's actions in defending sovereignty in the North Natuna Sea face China's unilateral claims. This analysis confirms that Indonesia's determination to rename the South China Sea to the North Natuna Sea is based on recognized international law, especially the 1982 UNCLOS. China's unilateral claims, including the Nine-Dash Line and traditional fishing grounds, are not recognized under the 1982 UNCLOS and are considered a violation of Indonesia's sovereign rights. Indonesia has taken concrete steps to defend its sovereignty, including registering the name change with the International Hydrographic Organization (IHO) and keeping it at the United Nations Headquarters, ensuring international recognition of Indonesia's claims. In addition, Indonesia has increased its defense capabilities in the Natuna region through military build-ups, including building military bases and conducting patrols, and has engaged in diplomatic efforts. These comprehensive measures demonstrate Indonesia's commitment to upholding international law and protecting its national interests from external claims.
