The boundary between a PTA and a free trade area (PTA) can blur, with almost all PTAs having the main objective of becoming a free trade agreement under the General Agreement on Tariffs and Trade. A common market is a customs union in which the movement of factors of production between Member States is relatively free. The EU has concluded trade agreements with these countries/regions, but both sides are negotiating an update. This question shows which goods of the countries are subject to customs duties at this preferential rate. In some circumstances, trade negotiations with a trading partner have been concluded, but they have not yet been signed or ratified. This means that the negotiations are over, but no part of the agreement is yet in force. Several hundred bilateral SAAs have been signed since the beginning of the twentieth century. The Trend project of the Canada Research Chair in International Political Economy lists approximately 700 trade agreements, the vast majority of which are bilateral.  Preferential trade agreements are concluded between countries to promote international trade and provide advantageous access to partner countries. . . .
