Or just mention the Sea of Japan. In Korea it's the East Sea. There's also an island in the Sea of Japan called Dokdo in Korea and Takashema in Japan. Ask your local Korean grocer if he's ever been to Takasheema, Japan then sit back and watch the world burn.
idk about all of Asia, but I lived in Korea for a long time and can confirm that Koreans in Korea are racist as fuck. They even look down on southeast asians. It was weird living there.
