Even in the absence of the constraints imposed by the most favoured nation and national treatment clauses, it is sometimes easier to obtain general multilateral agreements than separate bilateral agreements. In many cases, the potential loss resulting from a concession to a country is almost as great as that which would result from a similar concession to many countries. The benefits to the most efficient producers from global tariff reductions are significant enough to warrant substantial concessions. Since the implementation of the General Agreement on Tariffs and Trade (GATT, 1948) and its successor, the World Trade Organization (WTO, 1995), global tariffs have declined considerably and world trade has increased. The WTO contains provisions on reciprocity, the status of the most favoured nation and the domestic treatment of non-tariff restrictions. She has been involved in the architecture of the most comprehensive and important multilateral trade agreements of modern times. The North American Free Trade Agreement (1993) and the European Free Trade Association (1995) are examples of these trade agreements and their representative institutions. Below, you can see a map of the world with the biggest trade deals in 2018. Pass the cursor over each country for a rounded breakdown of imports, exports and balances. The logic of formal trade agreements is that they reduce penalties for deviation from the rules set out in the agreement.  As a result, trade agreements make misunderstandings less likely and create confidence on both sides in the sanction of fraud; this increases the likelihood of long-term cooperation.  An international organization such as the IMF can further encourage cooperation by monitoring compliance with agreements and reporting violations.  It may be necessary to monitor international agencies to detect non-tariff barriers that are disguised attempts to create barriers to trade.
 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 second is classified bilateral (BTA) if it is signed between two pages, each side could be a country (or another customs territory), a trading bloc or an informal group of countries (or other customs sites).
