NO. It is North Korea that is Communist. South Korea is a capitalist, liberal democracy.
What kind of goverment does South Korea have ?
North Korea's economic system is restricted due to it's communist form of government. South Korea's economic performance has no restrictions.
Realistically speaking, it's a relatively banal form of absolute (or totalitarian) dictatorship.
Many people have different beliefs, but I think that The greatest problem North Korea faces is poverty. Their form of government is very strict, and many are poor, hungry, and have no freedom.
No, Korea is a country. In fact it is two countries, North Korea and South Korea.
The nuclear tests in North Korea have absolutely nothing to do with "popular culture", "folk culture" or "language". They are simply an expression of the foreign policy and quixotic form of government that prevails in North Korea.

North Korea probably has one of the worst (if not the worst) economies in the world. Its people regularly starve and there is practically no innovation in business at all. However, North Korea's government is completely to blame for this lack of success primarily because (1) it enforces autarky and (2) it represses any form of individualism - key to starting and growing businesses.
This is the long-form name of North Korea.
It's similar to Americas.
