Final answer:
Ancient China's isolation was caused by natural physical barriers and a disinterest in trade.
Step-by-step explanation:
Ancient China's isolation was primarily caused by natural physical barriers such as deserts, mountains, and oceans. These physical features made it difficult for other cultures to invade or make contact with China. Examples of these barriers include the Gobi Desert in the north and the Himalayan Mountains to the southwest.
In addition to the physical barriers, the Chinese also had a disinterest in trade with other cultures. This further contributed to their isolation, as they did not actively seek out contact or engagement with foreign merchants or nations.
Overall, it was a combination of natural physical barriers and a disinterest in trade that led to ancient China's isolation from the rest of the world.
