Trade barriers do not include free trade zones. Free trade zones are actually areas where goods can be imported, stored, processed, and re-exported without being subject to the usual customs regulations. They are designed to promote international trade by reducing or eliminating barriers like tariffs, quotas, and taxes within that specific zone.
Trade barriers, on the other hand, are restrictions or regulations imposed by governments to control the flow of goods and services across borders. These barriers can include tariffs, quotas, embargoes, and other restrictions that make it harder for goods to be traded freely between countries. The purpose of trade barriers can vary, from protecting domestic industries to addressing trade imbalances.
In summary, free trade zones facilitate trade by reducing barriers within a specific geographic area, while trade barriers are restrictions imposed by governments to regulate international trade outside of these zones.
