I've been to North Korea 8 times over 12 years. Ask me anything. Headline: I made a documentary about exploring the border between China and North Korea - where tensions run high. AMA!
To this day, North Korea is the most isolated country in the world. I have been to North Korea eight times in the past 12 years. But on this trip, I wanted to explore the country's 880-mile border with China. Watch my ABC News documentary to see a glimpse inside the reclusive country from just across the river in China. http://abcnews.go.com/International/north-koreas-border-china-uneasy-alliance-fear-war/story?id=49565580
