Answer:
What role did Japan play in China's economic isolationist policies during the reign of the Ming dynasty?
Explanation:
During the last years of the reign of Wanli, emperor of the Ming dynasty, and those of his successors, the usual lack of silver, which was the main currency of the empire, caused a serious economic crisis.
In 1630, the new regime of Tokugawa of Japan, canceled most of its foreign trade with the European powers, thus closing another source of silver entry into China. These events occurred at almost the same time, which caused a dramatic increase in the price of silver and made paying taxes almost impossible for most provinces, economically isolating China.
