Mr. Li Linghua pointed out that it is worthwhile to discuss the United Nations Convention on the Law of the Sea and how to delimit China National Offshore under the circumstance of South China Sea issue . In his speech, he discussed seven subjects, including the meaning of the United Nations Convention on the Law of the Sea1982 and the main status of delimiting China National Offshore, how to define the territorial sea baseline, key cases of the delimitation of international oceans, the serious problems that exist in China's ocean demarcation. In his mind, there is no specific 200 nautical mile exclusive economic zone and the Limits of the Continental Shelf and this will lead to an unstable situation in the South China Sea to continue. In order to resolve the South China Sea dispute, we should do the following: According to the spirit of United Nations convention on the Law of the Sea 1982, Coastal governments should line out a 200 nautical mile single maritime boundary through the open and friendly bilateral or multilateral negotiations. Only in this way can the conflicts among the countries over the South China Sea be eliminated .
