The increase in international trade has both created and been supported by international regulatory groups like the world trade organization trade agreements like the North American free trade agreement. Anymore there isn’t a single country that is completely independent. All are independent, to some degree, on international trade for their own prosperity. Without international trade there’d be no need for international regulatory groups, and without the international regulatory groups international trade at the current massive scale would be impractical. The trade regulatory groups and agreements regulate the flow of goods and services between countries. They reduce tariffs which are taxes or imports, and make customs procedures easier. This make trading across national borders much more feasible.
