Many countries in early modern Europe adopted a policy of mercantilism, which theorized that a trade surplus was beneficial to a country. Mercantilist ideas also influenced how European nations regulated trade policies with their colonies, promoting the idea that natural resources and cash crops should be exported to Europe, with processed goods being exported back to the colonies in return.
An early statement concerning the balance of trade appeared in Discourse of the Common Wealth of this Realm of England, 1549: "We must always take heed that we buy no more from strangers than we sell them, for so should we impoverish ourselves and enrich them." Similarly, a systematic and coherent explanation of the balance of trade was made public through Thomas Mun's 1630 "England's treasure by foreign trade, or, The balance of our foreign trade is the rule of our treasure".
I resolved that we can create similar trade policies to improve our Balance of Trade and adopt them as follows:
NEVER EXPORT NATURAL RESOURCES AND CASH CROPS, WHICH ARE OUR RAW MATERIALS, TO FOREIGN NATIONS BUT EXPORT ONLY FINISHED PRODUCTS WHICH WE HAVE MANUFACTURED OURSELVES.
NEVER IMPORT FINISHED PRODUCTS FROM FOREIGN NATIONS BUT IMPORT ONLY RAW MATERIALS WHICH WE CAN USE TO MANUFACTURE FINISHED PRODUCTS OURSELVES.
This is because finished products have a higher value than raw materials the direction of trade of these, determine the balance of trade whether it will be a deficit or surplus.
