In their joint RSIS Commentary entitled “South China Sea Disputes: China has evidence of Historical Claims”, Dr Li Dexia and researcher Tan Keng Tat asserted that “China’s territorial claim is based on centuries of verifiable historical records, long-term use, treaties, international/customary laws plus records from the prodigious sea voyages of the Yuan and Ming dynasties”. I argue, however, that these evidences are unconvincing in the framework of international law.
