North Korean defectors
However, most defectors begin their escape through China. This is because the Tumen and Yalu Rivers (the rivers that make up the China-North Korea border) are much easier and safer to cross. However, most defectors do not stay in China because they are still in danger. Most defectors caught by the China government are either sent back to North Korea, where they would most likely be killed, or be sold as a wife or a sex slave in China. This is why most North Korean defectors try to go into second country before finally coming to South Korea. These countries include Mongolia, Russia, Vietnam, Cambodia, Laos, and Thailand.
