4.1.5 Trading Blocs and the World Trade Organisation (WTO) (Edexcel)


Last updated 6 Oct 2023

This study note covers Trading blocs and the World Trade Organisation (WTO)

A) Types of Trading Blocs:

  1. Free Trade Areas (FTAs):
    • FTAs involve the elimination or reduction of import tariffs and quotas on trade between member countries.
    • Goods and services can move freely within the bloc without customs duties.
    • Examples include NAFTA (North American Free Trade Agreement) and ASEAN Free Trade Area (AFTA).
  2. Customs Unions:
    • Customs unions go beyond FTAs by not only removing trade barriers but also establishing a common external tariff on imports from non-member countries.
    • Member countries coordinate their trade policies with respect to non-members.
    • The European Union (EU) is an example of a customs union.
  3. Common Markets:
    • Common markets not only remove trade barriers but also allow for the free movement of factors of production (capital, labor, and sometimes, technology).
    • It results in a higher degree of economic integration.
    • The EU, before the establishment of the Eurozone, was an example of a common market.
  4. Monetary Unions: Conditions Necessary for Success (Eurozone):
    • A monetary union involves a common currency shared by member countries. The Eurozone is an example.
    • Conditions for success include:
      • Fiscal discipline: Member countries need to maintain responsible fiscal policies to prevent economic imbalances.
      • Convergence criteria: Ensuring member countries have similar inflation rates, interest rates, and budget deficits.
      • A common monetary policy: Implemented by a central bank, like the European Central Bank (ECB) in the Eurozone.
      • Political commitment to the union: Member states must be willing to cede some economic sovereignty.

B) Costs and Benefits of Regional Trade Agreements:


  • Increased Trade: RTAs lead to increased trade among member countries, boosting economic growth.
  • Efficiency Gains: By reducing trade barriers, resources are allocated more efficiently.
  • Economies of Scale: Larger markets allow for economies of scale, reducing production costs.
  • Political Cooperation: RTAs can promote political cooperation and peace among member countries.


  • Trade Diversion: RTAs can lead to trade diversion, where members start trading more with each other but less with non-members.
  • Complexity: Compliance with different rules and regulations within the RTA can be complex for businesses.
  • Exclusion: Non-member countries can face trade disadvantages, potentially causing international tensions.
  • Loss of Sovereignty: Deeper integration may require members to cede some sovereignty in trade policy.

C) Role of the WTO in Trade Liberalization:

  • The World Trade Organization (WTO) plays a critical role in promoting global trade liberalization.
  • Key functions include:
    • Negotiation: Facilitating trade negotiations among member countries to reduce trade barriers.
    • Dispute Settlement: Resolving trade disputes through a rules-based system.
    • Monitoring: Monitoring trade policies and practices of member countries to ensure they comply with WTO rules.
    • Technical Assistance: Providing technical assistance to developing countries to help them participate in global trade.

D) Possible Conflicts Between RTAs and the WTO:

  1. Trade Discrimination: RTAs may discriminate against non-members, potentially violating WTO's most-favored-nation principle.
  2. Trade Diversion: If RTAs lead to trade diversion, they can be seen as contrary to the WTO's goal of reducing trade barriers globally.
  3. Inconsistent Rules: Conflicting rules between RTAs and WTO agreements can create legal and practical challenges.
  4. Preferential Treatment: WTO rules generally favor non-discrimination, while RTAs provide preferential treatment to member countries.
  5. Dispute Resolution: Disputes can arise when WTO and RTA rules conflict, requiring resolution mechanisms to reconcile differences.

In conclusion, understanding the various types of trading blocs, their costs and benefits, the role of the WTO, and potential conflicts between RTAs and the WTO is essential for comprehending the complex landscape of international trade agreements and their implications for global commerce and cooperation.
