Tibians are an ethical monority. In China, Japan, North Korea, or South Korea.

Tibians do not refer to a specific ethnic or cultural group, so it does not make sense to categorize them as an ethical minority in any of the countries mentioned - China, Japan, North Korea, or South Korea. It is important to note that ethical minority is not a commonly used term and may be potentially confusing or misleading.

To determine whether Tibians are an ethnic minority in China, Japan, North Korea, or South Korea, we need to explore some information sources. It is important to note that "Tibian" is not a recognized ethnic group and may refer to players or characters from the online game, Tibia.

3. Consult academic sources: Explore scholarly articles, books, or research papers about the ethnic composition of these countries. Academic resources may provide in-depth analysis and historical context regarding the status of Tibetans in each respective country.

4. Analyze news and media reports: News articles and media reports can offer insights into the presence and treatment of Tibetans in these countries. Be sure to check multiple sources to gain a comprehensive understanding.

By following these steps, you should be able to gather information on the status and distribution of Tibetans in China, Japan, North Korea, and South Korea. Remember to critically evaluate the sources you find to ensure reliability and accuracy.
