Kim was born in 1995 in Pyongyang but went to an international school in Macau, where he said he had plenty of friends from both the United States and South Korea -- two nations that are sworn enemies of North Korea.
"There are laws saying that North and South Koreans shouldn't interact, even outside Korea. Me and my South Korean friends, it was kind of awkward when we first met each other. But sometimes we shared our own stories from back home and realized how similar we are," he said.
The interview was published on YouTube, and the video description says it was conducted by former United Nations undersecretary general Elisabeth Rehn at United World College in Bosnia, where Kim has been studying.
He also said he never met Kim Jong Il, even though he always wanted to. Although he doesn't know why Kim Jong Eun was chosen to succeed Kim Jong Il as leader, he did say his own father was never in the running because he "wasn't interested in politics." He also referred to his uncle repeatedly as a "dictator" in the interview.
Kim said his parents influenced his world view -- his mother was an average North Korean who encouraged him to "live the same lifestyle as ordinary citizens."
"My dad said: 'Forget about your background, and live your life. Understand everything, that there are a lot of people who are hungry,'" Kim said.
The full interview is below, in two parts. It also includes some interesting footage of life inside North Korea.
