Explanation: China's isolation by the Himalayas prevented modernization and kept the ideas and technologies that were traded in Europe and India out of their country.

The Chinese built the Great Wall completely isolating themselves and protecting their pure Chinese cultures and traditions and they remained unaffected by the rest of Europe.
