South Korea is currently at war with North Korea in what is known as the Korean War.

China and the US also fought in what is known as the Korean War.

You can't claim SK and NK are at war with each other while implying China and US are not at war with each other. It's exactly the same war.

If you want to put it that way, the United Nations is at war with North Korea.
