I can't comment in any way disrespectfully of the Republic of Korea, or South Korea. South Korea has absorbed 27,000 to 28,000 refugees. It gives them a passport. They are entitled to citizenship under the constitution of the Republic of Korea, because South Korea asserts that it is the legitimate government of the Korean peninsula.
But it is true that a proportion, not a big proportion I think, feel alienated from some aspects of life in South Korea. Normally North Korean citizens are significantly shorter than their confreres in South Korea. They therefore tend to stand out and getting through that process of vetting and getting into a job, getting opportunities, is not easy in South Korea. Some would wish to and could make a useful contribution to countries like Canada, Australia, the United States, but we take very few because we say they can go to South Korea. But what must not happen is refoulement , the sending back of people to North Korea, because even if they left North Korea as economic migrants seeking a better life, if they are sent back they are very severely punished, some reportedly even with execution. Therefore it is a very serious thing to send them back and it should not happen.
