Why didn't China "discover" the new world? There are many differences and similarities between the Chinese and the Europeans. Some of their differences were social and economical. The Chinese did not see any reason to discover different countries. Even though the Chinese were far more advanced than the Europeans, they did not "discover" the new world. They were not just more advanced with things to do with ships and sea, but also with things on …

They did not see why they should go find new countries, because they thought they had everything, and that other countries could not give them anything new, because they were not as advanced as they were.
