A trade agreement (also known as a trade pact) is a large-scale tax, customs and trade agreement, which often includes investment guarantees. It exists when two or more countries agree on conditions that help them trade with each other. The most frequent trade agreements are preferential and free trade regimes to reduce (or remove) tariffs, quotas and other trade restrictions imposed on intermediaries. A trade agreement signed between more than two parties (usually neighbouring or in the same region) is considered multilateral. They face the main obstacles – to content negotiation and implementation. The more countries involved, the more difficult it is to achieve mutual satisfaction. Once this type of trade agreement is governed, it will become a very powerful agreement. The larger the GDP of the signatories, the greater the impact on other global trade relations. The largest multilateral trade agreement is the North American Free Trade Agreement between the United States, Canada and Mexico.  In general, trade diversion means that a free trade agreement would divert trade from more efficient suppliers outside the zone to less efficient suppliers within the territories.
Whereas the creation of trade implies the creation of a free trade area that might not otherwise have existed. In any case, the creation of trade will increase a country`s national well-being.  The notion of free trade is the opposite of trade protectionism or economic isolationism. Free trade policy has not been as popular with the general public. Key issues include unfair competition from countries where lower labour costs are reducing prices and the loss of well-paying jobs for producers abroad. The European Union is now a remarkable example of free trade. Member States form an essentially borderless unit for trade purposes, and the introduction of the euro by most of these countries paves the way. It should be noted that this system is governed by a Brussels-based bureaucracy, which has to deal with the many trade-related issues that arise between the representatives of the Member States. The creation of free trade zones is seen as an exception to the most privileged principle of the World Trade Organization (WTO), since the preferences of the parties to the exclusive granting of a free trade area go beyond their accession obligations.  Although GATT Article XXIV authorizes WTO members to establish free trade zones or to conclude interim agreements necessary for their establishment, there are several conditions relating to free trade zones or interim agreements leading to the creation of free trade zones.
Another important type of trade agreement is the Trade and Investment Framework Agreement. TIFA provides a framework for governments to discuss and resolve trade and investment issues at an early stage. These arrangements are also a means of identifying and working, if necessary, for capacity building.
