What is the basic principle behind mercantilism?

The basic principle of mercantilism is that a nation's wealth and power are best served by increasing exports and accumulating precious metals, primarily gold and silver. This economic theory emphasizes a positive balance of trade, where countries aim to export more than they import. Mercantilism encourages government intervention in the economy to protect domestic industries and promote national interests. Ultimately, it views international trade as a zero-sum game, where one nation's gain is another's loss.
