Korean diaspora
Korean is spoken by the Korean people in both South Korea and North Korea, and by the Korean diaspora in many countries including the People's Republic of China, the United States, Japan, and Russia. Currently, Korean is the fourth most popular foreign language in China, following English, Japanese, and Russian. Korean-speaking minorities exist in these states, but because of cultural assimilation into host countries, not all ethnic Koreans may speak it with native fluency.
