Since the beginning of the 20th century, several hundred bilateral THPs have been signed. The Canada Research Chair in International Political Economy`s TREND project lists approximately 700 trade agreements, the vast majority of which are bilateral.  Regional trade agreements depend on the importance of commitment and agreement between Member States. Most of the reciprocal agreements covered by this instrument are free trade agreements. Free trade agreements (FTAs) remove barriers to trade between members and provide preferential access to markets on a reciprocal basis. In addition to trade in goods, free trade agreements generally cover trade in services and investment rules and remove tariff and non-tariff barriers. They may also include a number of provisions relating to customs cooperation and trade facilities, as well as harmonising standards and promoting regulatory cooperation in various areas. Preferential trade agreements (EPZs) are formal trade agreements between countries that benefit from trade between them. In many cases, these benefits are the local product; Nearby countries are better able to trade because of lower transport costs and increased transparency opportunities. When trade agreements are constructed in this regional way, they are sometimes referred to as regional trade agreements or RTAs. The question of whether EPZs increase or divert trade are the subject of much discussion.
The basic principles of these two arguments are that while the PTA may promote trade that would not otherwise exist, it also has the potential to steal trade that would otherwise take place with members outside the EPZ and far from the cheapest producer. Ideally, the creation of trade should take precedence over trade diversion.  In principle, we can distinguish between unilateral trade agreements and systems (offered from one side to the other) and reciprocal trading systems (negotiated and agreed upon by both parties). Full integration of Member States is the last level of trade agreements. First, it is one of the names that are sometimes used for free trade agreements, to emphasize their preferential nature, in contrast to trade liberalization under the WTO or unilateral reduction of tariffs. A Regional Trade Agreement (RTA) is an example of PTA. In the United States, some industries, such as automakers and electronics manufacturers, favour ATRs because these agreements allow these industries to exploit low production costs in other countries in the hemisphere, while avoiding competition from European and Japanese manufacturers, which they would face in a multilateral agreement.  Each free trade agreement is negotiated and approved separately by the participating countries. A country may be a member of several free trade agreements. Preferential rules of origin are applied to prevent third countries from benefiting from preferential tariffs under a free trade agreement without presenting reciprocal benefits.
Regional trade agreements refer to a treaty signed by two or more countries to promote the free movement of goods and services beyond the borders of its members. The agreement contains internal rules that Member States comply with each other. As far as third countries are concerned, there are external rules to which members comply. The World Trade Organization unilaterally designates preferential trade agreements and reciprocal trade agreements as regional trade agreements. All of the above agreements are free trade agreements, but for a variety of reasons, members prefer to name them under another name. In many cases, these names reflect the broader scope of agreements: many recent free trade agreements go beyond the scope of traditional trade agreements and cover areas such as public procurement, competition, intellectual property, sustainable development, labour and the environment, etc. A free trade agreement removes all barriers to trade among members, which means that they can freely move goods and services between them.
