Asia (Japan, China, North and South Korea)Today world is concerned about Asia. Japan, China, Korea are located very closely together. So culturally and historically, they have many common things. However, they were very hard to stick and get along together.First of all, this is relationship and history between Japan and Korea. Korea was Colonial of Japan from 1910,Aug to 1945s Aug for thirty six years. Japan army did genocide Korean, and used Koeran as an experiment on a living body. Moreover, they let Korean only speak and learn Japanese, so some old Korean people can speak Japanese, and Japan forced Korean to change their name to Japanese style name. Youth Korean man was force commandeered to army. Many patriots fought for liberation till died. The worst thing was they dragged Korean women and treated as a military sexual slave. This issue is not solved yet, and it still encourages national conflict. The women request reparation. I think Japan should apology sincerely, and military sexual slave issue is not just conflict between two countries, is a question of human rights. Even though I am also Korean, I also want South Korea apology to Vietnam women. All of worlds have to observe and be careful not to reappear it in everywhere. Most of old Korean doesn’t think Japan as friend, but young generations seem try to maintain good relationship even though they also still remained uncomfortable emotion against Japan. The two countries are also at odds over territorial clams to a group of small islands, Dokdo in the East Sea of Korea controlled by South Korea.Second, this is about the China. China is one of big country economically, but he also has many conflicts historically. Once, China was very strong country and wealth. The well known wars between China and Japan are “First-Sino Japanese War, and NanJing Massacre 1937, Dec-1938, Jan). Japanese Army killed about 15,5337 Chinese at NanJing. This is the big reason that Chinese have hostility against Japan.Sometimes these history issues are caused to a civic campaign to boycott Japan products. Most of Chinese also don’t like Japanese as much as Korean. However, what is done cannot be undone. I think the best way peacekeeping is making efforts not to happen again, and building good friendship. In additional, theses countries should understand and help each other, then also can be powerful countries like Europe.Next, North Korea is named as “axis of evil”. North Korea supposed to have united with South Korea, but unfortunately, we are divided. North Korea used to close a country to foreign intercourse, but since when they have opened their door little and little bit because of money. Maybe they realized how global and fund is important. Most of their purpose open door is for strengthen military weapon. South Korean couldn’t go to North Korea at all, but after the president De Jung Kim of South Korea announced “Sunshine Policy” 1998, Apri, 03, South Korea tried to do interchange cooperation. As the result, we can go some permitted places; however, a few days ago, a South Korean tourist was killed by North army in North Korea.Finally, in spite of similar culture they seem having difficulties to be together like oil and water. Actually, there is no dispute between each countries people as much as countries. Historically and politically we might hate each other, and try to get only their own interest, but new generations of these countries has tried to get know each other and exchange their culture and language. A lot of students go to Japan and China, and come to South Korea as much as America. They listen to mutual music and watch mutual dramas. Asia would be great and important a region in the world if they harmony with love instead of debate or wars.
