The north korean people are starving due to a lack of political international medical aid and wise farming methods.

I don't know whether this is the best way of phrasing it , but the statement is true.

North Korea is a dictatorship, and the government is not allowing medical aid from abroad because they don't want to loose their control of the territory.

They also don't use the methods of farming found in other places and which proved to be more efficient.

Ibelieve it is- a mixed economy offers some protection for consumer rights but still allows a good deal of choice.
