Meaning Of Pta Agreement
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.  A preferential trade zone (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. Preferential trade agreements negotiated by the EU give privileged access to the markets of the countries concerned. As such, they are an exception to the first principle of the World Trade Organization, namely equal treatment of all trading partners (MFN). The Community has concluded both unilateral preferential (preferential regimes granted by the Community without reciprocity) and conventional preferential regimes (reciprocal agreements establishing free trade zones). This regime is determined by the origin of products subject to tariff preferences.
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.

Countries are more likely to participate in ATPs when they have lower transportation costs and larger economies. Third, countries of similar economic size should benefit the most from PTA training. Economic determinants such as GDP, similarity in economic size and distance between countries rightly predict more than 80% of the PTA from 2020.
 The remaining PTAs may be attributed to political preachers.
