Did the great wall of china help isolate from Europe and middle east?

While the Great Wall of China was primarily built for defense and border control, it did not completely isolate China from Europe and the Middle East. Trade and cultural exchange still occurred along the Silk Road, which connected China with these regions. The Silk Road was a network of trade routes that extended from China to the Mediterranean Sea and beyond. It facilitated the exchange of goods, ideas, and technologies between different civilizations. Although the Great Wall of China may have presented some challenges for travelers, it did not completely prevent contact between China and the rest of the world.
