In principle, free trade at the international level is no different from trade between neighbours, cities or states. However, it allows companies in each country to focus on the production and sale of goods that make the best use of their resources, while others import goods that are scarce or unavailable domesticly. This mix of local production and foreign trade allows economies to grow faster and, at the same time, better meet the needs of their consumers. The anti-globalization movement is almost by definition opposed to such agreements, but some groups that are normally allied within this movement, for example the green parties.

A common market is a kind of trade agreement in which members remove internal barriers to trade, adopt common policies with regard to non-members and allow members to move their resources freely among themselves. On the other hand, some local industries benefit. They are finding new markets for their duty-free products. These industries are growing and employing more labour.
