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 preferential trade agreement requires the least commitment to removing trade barriers Trade barriers are legal measures taken primarily to protect a country`s national economy. They generally reduce the amount of goods and services that can be imported. These barriers are put in place in the form of tariffs or taxes and, although Member States do not remove barriers between them. There are also no common trade barriers in preferential trade zones. Member States of a Customs UnionA customs union is an agreement between two or more neighbouring countries for the removal of trade barriers, the abolition or abolition of tariffs and the abolition of quotas. These unions have been defined in the General Agreement on Tariffs and Trade (GATT) and are the third stage of economic integration. The Committee on Economic Relations and Policy of Economic Union and The Policy of Economic Union and Eastern Europe of the Preferential Trade Area (including Preferential Trade Agreements, PTA) is a trading bloc that offers preferential access to certain products from participating countries. This requires a reduction in tariffs, but not in their total abolition. A ZEP can be implemented through a trade pact.
This is the first step in economic integration. The border between a EPZ and a Free Trade Area (EEA) can be blurred, as almost all ATPs have the main objective of becoming a free trade agreement in accordance with the General Agreement on Tariffs and Trade. Regional trade agreements have the following advantages: trade agreements open many doors. With access to new markets, competition intensifies. Increasing competition is forcing companies to produce better quality products. It also leads to greater diversity for consumers. If there are a variety of high quality products, companies can improve customer satisfaction. Full integration of Member States is the last level of trade agreements. Businesses in Member States benefit from increased incentives to trade in new markets as a result of the measures contained in the agreements. A free trade agreement removes all barriers to trade among members, which means that they can freely move goods and services between them.
When it comes to dealing with non-members, each member`s trade policies continue to come into force. Given the recent proliferation of bilateral TTPs and the emergence of mega-PTAs (broad regional trade agreements such as the Transatlantic Trade and Investment Partnership (TTIP) or the Trans-Pacific Partnership (TPP), a global trading system managed exclusively under the WTO now seems unrealistic and the interactions between trade systems must be taken into account. The increasing complexity of the international trading system resulting from the proliferation of EPZs should be taken into account when considering the choice of countries or regions used by countries or regions to promote their trade relations and environmental agendas.  ATPs have grown rapidly; In the 1990s, there were just over 100 PTAs. In 2014, there were more than 700.  A common market is a kind of trade agreement in which members remove internal trade barriers, adopt common policies on relations with non-members, and allow members to move their resources freely among themselves.
