Maoism & Marxism

It was interesting in class the other day to learn the difference between the two ideologies. Much has been portrayed in our society that the all Communist regimes have been classified as Marxist regimes. However, that is not the case for China. Marx believed that his ideology would come to the most industrialized nations first; like the United States, Britain, France and the Netherlands. In the case of China, it was very underdeveloped and a very poor nation, which contradicts Marx's statement about his movement starting in the most industrialized nations. This goes for much of the analysis of Marxism that China does not meet many of the requirements that Marx explained in his Communist Manifesto. It seems that Marx was wrong not only with China, but places like Cuba, Vietnam, and North Korea, which are underdeveloped nations that have Communist regimes.
