Which policy is a country using when it regulates its colonies imports and exports to produce a favorable balance of trade?

The policy a country uses when it regulates its colonies' imports and exports to achieve a favorable balance of trade is known as mercantilism. This economic theory emphasizes the importance of accumulating wealth, primarily gold and silver, through a positive balance of trade by exporting more than importing. It often involves government intervention to control trade and promote domestic industries, while restricting foreign competition.
