While Korean is spoken in North Korea as well, it's considered a different dialect with distinct differences in vocabulary and pronunciation.
However, if you're interested in countries with large Korean-speaking populations, here are some to consider:
* China: A significant number of ethnic Koreans live in China, primarily in the northeastern provinces.
* Japan: There's a substantial Korean community in Japan, many of whom speak Korean.
* United States: The US has a large Korean diaspora, particularly in major cities like Los Angeles, New York, and Chicago.
* Canada: Similar to the US, Canada also has a sizable Korean diaspora.
It's important to note that the term "Korean speaking" can be somewhat ambiguous. While the above-mentioned countries have large Korean populations, the prevalence of Korean spoken as a primary language may vary depending on the region and demographics.
