Globalization has led to the revitalization and the revival of the local and geological identity consciousness that was gradually declined, to some extent, old ideology come out with new shapes. Ethnical identity，national identity and other issues are facing more complex situation and problems than ever before. To solve the political disputes under international atmosphere and tension existing in Northeast Asia, we must abandon the original single-mode construction of contemplated Economic Community, on the basis of full argument on the need to build the new ideas of "Cultural Economic Community" in Northeast Asia. Since the simple economic link is only to maintain the relationship between countries, it is necessary to establish a close network between countries and people, if there is the possibility, this network based on the mutual benefit in political, economic, cultural, religious, educational, science and technology and so on. In the study of the Northeast Asian Community, the dilemma of cross-cultural communication should be fully considered: language barrier in social communication; cultural barriers: differences in religious and cultural values; economic development level and the negative factors for timely assistance; unique social organizational structure, the overall social situation. Based on the actual situation of each country in Northeast Asia and the comprehensive consideration of elements such as national culture history, inter-ethnic contact and exchanges, we should give full play to the close cultural and historical ties and the cultural identity of transnational people in the region as the regional multilateral relations exchange platform, and actively build the Northeast Asia "cultural and economic community", this is the possible path to smoothly solve the complex political disputes in this region.
