Introduction

 It is a great tragedy that Korea peninsula remains divided in two, although South Korean and North Korean have the same ethnic group. So, Korea have to be unified as soon as possible. Think about the case of Germany. They could achieve their unification thanks to economic assistance. Then, have you heard about any economic cooperation between South Korea and North Korea? One of the most serious problem that blocks Korea from unification is the economic gap between South Korea and North Korea. It is an activity which contains 'exchange' and 'investment'. It mainly aims economic profit and it is done by both South Korean and North Korean.
