Abstract: Geopolitical theories advance with the times which should be shed dynamic perspectives on the geopolitics. By reviewing on traditional geopolitical theories, they have been shifting from objective spatial viewpoints of ‘territorial expansion’ to focus on interaction between politics and economy, and then to the current emphasis on ‘cultural regions sovereignty’. The content dimension of national security has expanded from the field of military and political security to the field of economic, social, environmental security. The scale dimension has extended upward from international level to the international system and down to individual level. In the new era, the country needs new views of national security that based on the cultural identity and targeted enhancement of the soft power. This paper argues that geo-cultural strategy on the strength of cultural regions will become a powerful complement to traditional geopolitical theory.
