對於「中菲南(中國)海案」,中國採取不參加的策略並不會影響該程序的運行乃至裁決的作出。相反,如果中國參加到仲裁程序當中,則可以在仲裁員的指定、證據的提供等各方面更好地促使仲裁庭作出更為公正的裁決。因此,目前的不參加策略並不是最佳選擇。從《聯合國海洋法公約》強制性爭端解決程序以及1969年《維也納條約法公約》的解釋規則來看,對於申請仲裁的兩個前提條件,即「雙方自願選擇的其他方法無法解決」、「交換意見的義務」菲律賓都沒有能夠加以有利證明並充分予以滿足。另外,該仲裁申請的內容屬於被中國2006年《聲明》所排除的爭端。因此仲裁庭沒有管轄權。從先佔、歷史性權利等國際法規則來看,菲律賓的主張在實體層面缺乏法律依據。
It is unwise for China not to participate in the arbitral procedure under Annex VII to the United Nations Convention on the Law of the Sea. If participated in this procedure, China would receive a comparative equitable award by appointing arbitrator, providing evidence and so on. From the point of compulsory procedures entailing binding decisions of UNCLOS and interpretation of Vienna Convention on the Law of Treaties, the tribunal under Annex VII has no jurisdiction over the disputes between China and the Philippines, because the Philippines' claims did not satisfied the requirements of obligation to exchange views, and no settlement reached by recourse to a peaceful means of their own choice, of disputes excluded by 2006 Declaration of China. From the point of international law, such as preoccupation and historic rights, the claims of the Philippines are not well found.
