Explanation:
China's isolation affected trade because their limited contact with others left them not knowing how to handle foreigners like the Portuguese who came to trade. This led them to believe the Portuguese were barbarians. They had the Portuguese pay in gold and silver because their textiles and metals were not good enough to trade with China's silk and porcelain.They set up a trading post and eventually China opened up to trading with other Europeans.
