Vietnam and Korea have a lot of aspects similar both in historically and geopolitically. Especially, the difficulties that Vietnam is going through, due to the sovereignty issues surrounding the South China Sea, has much to suggest us. For Korea, who is facing difficult national issues such as the sovereignty of Dokdo island as well as the naming of ‘The East Sea’ etc., the timing seems just right in reviewing the Vietnam’s case study. Therefore, the purpose of this research is to understand the Vietnam’s response methodology and the status on territorial education regarding the sovereignty issues they are facing. As a result of the research, in Vietnam, the East Sea (Biển Đông) related academic conferences are led annually by the government organizations such as Vietnam Diplomatic Academy, Vietnam Academy of Social Sciences, East Sea (Biển Đông) Research Foundation, and Vietnam Legal Society. The East Sea (Biển Đông) Research Foundation offers a variety of academic awards in order to encourage researchers' interests and participations. In addition to the academic researches, Vietnamese people, via SNS, are propagating throughout the world the illegal activities by Chinese and their unfair situation that they face, in order to attract worldwide netizens’ interest and sympathy. At school, students strengthen their determination in protecting their territories by listening to lectures on ‘The Islands’ in the East Sea or by participa ting themselves in performances that symbolize the Vietnamese territory. In addition, a systematic territorial education is being conducted through the regular courses such as History, Geography, Civic Education, and Defense Education
