Economists have expressed their opinion that the economic trade between countries brings about economic prosperity as well as peace. Their opinion is based upon that the trading countries do not want to face the situation of decline in their welfare and benefits due to not participating in economic trade. They argue that economic trades between countries give them the opportunities of conversation, decrease misunderstanding, and leads them to peaceful mind and behavioral attitude to adjust the political conflicts. On the basis of this kind of opinion and the reunification of Germany, the economic trade between South and North Korea has been suggested as the most efficient measure to maintain the peace in Korean Peninsula. It has been twenty four years since the economic trade between South and North Korea was triggered in January, 1989 under President Noh Taewoo’s Declaration of July 7 in spite of several crises. The total turnover between South and North Korea is about US$ 18.3 billion from 1989 to 2012, out of which US$ 9.2 billion is the export to the North and US$ 9.1 billion is the import from the North. Since the end of cold war, South Korea and China have established diplomatic relations on July 24, 1992, and they have become strategic cooperative partners. The total turnover between South Korea and China was US$ 6.4 billion in 1992, and it increased to US$ 215.2 billion in 2012. On the other hand, the total turnover between North Korea and China amounts to US$ 5.9 billion in 2012, which is around three times as much as that between South and North Korea.
The results of theoretical analyses are summarized as follows. First of all, exports and imports between South and North Korea turned out to ease the conflicts between two countries. Therefore, ‘theory of peace through trade’ by the liberalists was supported here. Secondly, it turned out that the economic trade between North Korea and China affects to easing conflicts between South and North Korea only if South Korea and China are in friendly partnership. It implies that China induces North Korea to ease the conflicts between South and North Korea. Thirdly, exports from South Korea to China affects to easing conflicts between South and North Korea only if North Korea and China are friendly partners politically. Imports from China to South.
Korea affects to easing conflicts between South and North Korea only if North Korea and China are in antagonistic relationship politically. Empirical analysis shows that the difference quotient in the total turnover between South and North Korea turned out to have a significant positive relationship with the conflict index of the former year. It implies that the increase of the difference quotient in the total turnover between South and North Korea is likely to ease the conflicts between two countries. On the other hand, the difference quotient in the imports turned out to have significant positive relationship with the conflict index of the former year. It tells that the increase of the imports is likely to ease the conflicts between South and North Korea. While the expand of trade with China will ease the conflicts in Korean Peninsula from the theoretical viewpoint, empirical analyses present opposite results. It implies that the relationship between North Korea and China since the end of cold war is not the same as that before the end of cold war. It also tells that North Korea puts the higher political priority to developing the nuclear weapon and long-range missile. Inter-Korean policy has to keep consistency focusing economic cooperation apart from political issues. Long-term goal of inter-Korean policy should be unification, although short-term one is peace and stability in Korean Peninsula.
