SEOUL (Reuters) - It's much more dangerous, and twice as expensive, to defect from North Korea since Kim Jong Un took power in Pyongyang three and a half years ago, refugees and experts say, and far fewer people are escaping from the repressive and impoverished country.
With barbed-wire fencing erected on both sides of the Tumen River that marks the border with China, more guard posts and closer monitoring of cross-border phone calls, the number of North Koreans coming annually to the South via China has halved since 2011.
