Question

Quizplus · Accepted Answer

The doctrine of mercantilism, which was prevalent during the time, emphasized the importance of accumulating bullion (gold and silver) as a measure of national wealth and power. This doctrine discouraged negative trade balances, which would occur if bullion was exchanged for goods, thus making the Portuguese reluctant to trade bullion for Asian products.
