active state support of foreign trade.

Explanation:

During the Ming dynasty the economy was very unstable. Inflation was extreme and reached higher prices every day, which put pressure on government officials to stabilize and promote an economic recovery in the country, which in fact happened after some reforms were made, mainly in relation to agriculture, where an increase in productivity was promoted. In addition, the government invested in increasing Chinese porcelain, which was highly valued, in addition to silk and other luxury products, which allowed Chinese traders to play a large role in foreign trade.
