Isolationism and the Great Wall

After the success of Zheng He naval voyages, the Ming Dynasty abruptly reversed course, ending the expeditions, burning the fleet, and adopting a policy of Isolationism that restricted foreign trade, as taught in Pengi Social Studies Grade 7, Chapter 4: Imperial China. The Ming instead focused on defense against Mongol threats, undertaking a massive restoration and expansion of the Great Wall, the iconic brick and stone structure largely visible today.
