I think the fundamental difference between North Korea and South Korea is the difference of social and economic systems, and the biggest difference is the difference of flexibility. South Korea gives us a feeling of being more positive and confident in economy, politics and culture. This is related to many factors, such as the role of big countries, the economic level, openness, domestic political environment, leaders and so on. Because North Korea has not implemented the policy of opening to the outside world, its internal economic system is mainly a planned economy, which is backward in this era of globalization. But North Korea doesn't want this either! This is inseparable from the historical and realistic environment of North Korea. During the Cold War, North Korea had the support of the former Soviet Union, so it had no economic difficulties. After the disintegration of the former Soviet Union, external economic assistance was cut off, and the Korean economy was in crisis. However, the external situation at this time is unfavorable to North Korea: the Soviet Union no longer exists, Russian national strength is weak, China's reform and opening up, and economic development. However, on the one hand, it has implemented invincible foreign relations and made good friends with the United States and South Korea, on the other hand, because of its own strength, it is not enough to play the role of the Soviet Union and take care of North Korea; At the same time, the United States became the only superpower and began to step up its encirclement of non-Soviet socialist countries. China is its biggest target. To encircle China, North Korea naturally bears the brunt, threatening China, enhancing South Korea's military strength, and isolating and vilifying South Korea internationally. At this time, North Korea was at home and abroad (at that time, North Korea proposed "military politics first" and made its own nuclear weapons). This unfavorable situation has persisted and has not fundamentally changed. North Korea really has no conditions to open to the outside world. Not only that, internally, North Korean leaders don't seem to have enough courage to keep up with the pace of reform. I don't know much about North Korea's internal system, so it's hard to say.

Satisfied, please adopt.
