Every country in this world has their own distinct culture and uniqueness. These cultures, traditions and national identity should be preserved. For many western countries, their uniqueness is in the diversity of their population (multiracial, multi ethnic, immigration etc). For East Asia, like Japan, Korea and China the uniqueness lies in the homogeneous population that stretch back to 2000 years ago that shaped the distinct culture since then. Unlike western, eastern identity lies not in individualism, but in the community as a whole (i.e. homogeneous in East Asia). The loss of this uniqueness in eastern countries means the loss of national identity and thus the loss of nation itself.
