International Trade Under The GATT/WTO Multilateral Regime Vis-à-vis Development and Least Developed Economies: Spotlight on Nigeria

Contributor: Olugbade Johnson

Introduction

International trade plays a significant role in economic growth, development and international economic cooperation. The contemporary multilateral trading system emerged from efforts to prevent a recurrence of the economic instability and protectionism that characterised the interwar period. The Bretton Woods Conference of 1944 laid the foundation for the establishment of the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (World Bank), while the General Agreement on Tariffs and Trade (GATT) was concluded in 1947 to promote trade liberalisation through tariff reductions and the elimination of discriminatory trade practices.^[1]

The Uruguay Round negotiations subsequently culminated in the Marrakesh Agreement Establishing the World Trade Organisation (WTO), signed in 1994 and brought into force on 1 January 1995. Unlike GATT 1947, the WTO provides a permanent institutional framework for multilateral trade relations and administers a broader body of rules governing trade in goods, services and related matters.^[2] The GATT/WTO regime is principally founded on non-discrimination, transparency, reciprocity and progressive trade liberalisation, to create a more open and predictable international trading system.^[3]

Applying these principles, however, raises important developmental questions. Developing and least-developed countries do not participate in international trade from positions of equal economic strength. Many face limited productive capacity, infrastructure deficits, dependence on primary commodities, restricted access to finance and technology, and institutional constraints that affect their ability to compete effectively in global markets. The GATT/WTO framework therefore recognises, to varying degrees, the particular circumstances of these economies through provisions on special and differential treatment, technical assistance, longer implementation periods and other forms of flexibility intended to facilitate their integration into the multilateral trading system.

Nigeria provides an important context for examining the relationship between multilateral trade rules and development. As one of Africa’s largest economies, a WTO Member and a State Party to the African Continental Free Trade Area (AfCFTA), Nigeria possesses significant trade and developmental potential. Nevertheless, structural constraints, dependence on commodity exports, limited industrial competitiveness and persistent regulatory and infrastructural challenges continue to affect its ability to derive maximum benefit from international trade.^[4] Nigeria’s experience therefore illustrates the broader question of whether, and to what extent, the GATT/WTO multilateral regime adequately accommodates the developmental needs and economic realities of developing economies.

Against this background, this article examines international trade under the GATT/WTO multilateral regime with particular emphasis on developing and least-developed economies. It analyses the regime’s objectives and guiding principles, the mechanisms designed to address developmental disparities among WTO Members, and the opportunities and challenges the system presents for developing and least-developed countries. It then evaluates Nigeria’s participation in the multilateral trading system, identifying the extent to which the existing framework promotes, constrains or can be better utilised to advance the country’s trade and development objectives.

Meaning and Evolution of International Trade

International trade refers to the exchange of goods, services and capital across national borders for economic benefit.^[5] Although international trade has existed for centuries through commercial networks such as the Silk Road and trans-Saharan trade routes, the contemporary multilateral trading system emerged after the Second World War. Before this period, international commerce was characterised by high tariffs, import quotas and other protectionist measures, particularly during the Great Depression. These restrictions reduced global trade, weakened economic cooperation and contributed to widespread economic instability. Consequently, world leaders recognised the need for an international framework to promote freer, more predictable trade while reducing the risk of future economic crises.^[6]

This objective helped lead to the Bretton Woods Conference in New Hampshire, United States, in July 1944. Representatives of 44 countries met to establish institutions that would promote post-war economic stability and international cooperation. The Conference led to the establishment of the IMF, principally to promote international monetary cooperation and assist members experiencing balance-of-payments difficulties, and the World Bank, which was established to support post-war reconstruction and economic development. These institutions remain important components of the international economic system and continue to support conditions relevant to global trade and development.^[7]

Alongside these initiatives, efforts were made to establish an ITO to provide a comprehensive institutional framework for international commerce. Although the Havana Charter for an ITO was adopted in 1948, it never entered into force because it failed to secure the necessary ratification. Consequently, the GATT 1947, originally conceived as a provisional arrangement, became the principal multilateral framework governing international trade in goods. Its central objectives included reducing tariffs, eliminating discriminatory trade practices and promoting trade liberalisation through multilateral negotiations among its contracting parties.^[8]

Over the following decades, the GATT framework developed through successive rounds of trade negotiations, including the Kennedy Round, Tokyo Round and Uruguay Round. These negotiations contributed significantly to tariff reductions and greater access to international markets. However, GATT had important institutional and substantive limitations. It lacked the institutional structure of a permanent international organisation, operated with comparatively weak dispute-settlement mechanisms and did not comprehensively regulate emerging areas of international commerce, particularly trade in services and intellectual property rights.^[9]

To address these shortcomings, the Uruguay Round negotiations culminated in the adoption of the Marrakesh Agreement Establishing the WTO in 1994. The WTO commenced operations on 1 January 1995 and established a permanent institutional framework for administering the multilateral trading system. Unlike GATT 1947, the WTO has a broader mandate covering trade in goods, services and trade-related aspects of intellectual property rights. It also provides a more structured legal and institutional framework for regulating trade relations among Members and promoting greater certainty and predictability in international commerce.^[10]

Today, the WTO, together with the IMF and the World Bank, forms a central part of the modern international economic architecture. Although each institution performs distinct functions, their complementary roles contribute to international trade, economic cooperation and development. The transition from GATT to the WTO therefore marked a significant development in international economic law by creating a more comprehensive, rules-based, and institutionalised framework for international trade.^[11]

Objectives, Principles and Significance of the GATT/WTO Multilateral Trading Regime

The establishment of the GATT and its successor, the WTO, reflected the need for a stable, predictable and non-discriminatory framework for regulating international trade. The multilateral trading system seeks to promote economic cooperation by reducing trade barriers, improving market access and ensuring that international trade operates according to agreed rules rather than unilateral national measures.^[12]

A principal objective of the GATT/WTO regime is trade liberalisation through the progressive reduction of tariffs and other barriers that restrict cross-border trade in goods and services.^[13] The regime also seeks to promote fair and predictable conditions of competition among Members by prohibiting or regulating discriminatory and trade-distorting measures and limiting unjustifiable restrictions on international trade.^[14]

Developing and Least Developed Economies under the GATT/WTO Multilateral Trading Regime: Spotlight on Nigeria

Developing and least-developed countries constitute a significant proportion of WTO membership. While the multilateral trading system establishes common rules and obligations for its Members, it recognises significant differences in their levels of economic development, industrial capacity and technological advancement. Consequently, the GATT/WTO framework contains measures designed to facilitate the participation of developing countries and LDCs in international trade by allowing greater flexibility in implementing certain obligations and supporting their integration into the global trading system.^[15]

One principal mechanism for addressing these developmental disparities is Special and Differential Treatment (S&DT). Various WTO agreements grant developing countries and LDCs longer implementation periods, provide for technical assistance and capacity-building, and, in certain circumstances, impose differentiated or more flexible obligations. These provisions aim to enable such countries to implement WTO commitments in a manner that accounts for their particular developmental and institutional constraints.

These provisions seek to give developing countries and LDCs the flexibility and institutional support necessary to strengthen domestic capacity and participate progressively in international trade without being disproportionately disadvantaged by competition from more advanced economies.^[16] Despite these flexibilities, developing economies continue to face significant challenges within the multilateral trading system. Many remain heavily dependent on primary commodity exports, exposing them to fluctuations in international commodity prices. Inadequate infrastructure, limited industrialisation, insufficient technological capacity and restricted access to international finance also constrain their competitiveness in global markets. Consequently, the benefits of trade liberalisation are not distributed evenly among WTO Members.^[17]

Market access presents a further challenge. Although developed countries generally advocate trade liberalisation, some maintain agricultural subsidies, tariff peaks and non-tariff barriers that restrict exports from developing economies. Such measures can weaken the competitiveness of producers in poorer economies and limit their effective participation in international trade. Critics therefore argue that, despite the WTO’s commitment to non-discrimination, significant inequalities persist in the global trading system.^[18]

Nigeria’s experience illustrates both the opportunities and constraints facing developing economies under the GATT/WTO regime. Nigeria has been a WTO Member since 1 January 1995 and has participated in the multilateral trading system for decades. Its membership provides access to the rules and institutional mechanisms of the multilateral trading system, as well as a platform for engagement in international trade negotiations.^[19]

Nevertheless, Nigeria’s ability to benefit fully from the multilateral trading system remains constrained by structural weaknesses in its economy. Its export structure remains heavily dependent on crude oil, while limited diversification and value-added production restrict its competitiveness across a broader range of international markets. These constraints limit Nigeria’s capacity to take full advantage of the market-access opportunities available under the WTO framework.^[20]

To maximise the benefits of the multilateral trading system, Nigeria should deepen economic diversification, industrial development and export promotion. Greater investment in infrastructure, technology, human capital and value-added production would strengthen its productive and export capacity. Nigeria should also continue to engage actively in WTO negotiations while leveraging the AfCFTA to expand intra-African trade, promote economic integration and strengthen its competitiveness in regional and global markets.^[21]

Conclusion

The development of GATT and its subsequent transition into the WTO marked a significant stage in the evolution of international trade law. By establishing a rules-based multilateral trading system, the WTO has promoted trade liberalisation, reduced discriminatory trade practices and strengthened cooperation among Members. Its principles of non-discrimination, transparency, predictability and fair competition continue to provide an important legal foundation for international commerce.

For developing countries and LDCs, however, the multilateral trading system presents both opportunities and persistent challenges. Although WTO membership provides access to international markets, technical assistance, and greater participation in global trade, many developing economies still face structural constraints, including inadequate infrastructure, dependence on primary commodity exports, and limited industrial capacity. These challenges often restrict their ability to compete effectively in global markets despite the availability of S&DT provisions.

Nigeria’s experience reflects many of these difficulties. Although participation in the multilateral trading system provides opportunities for market access and international economic engagement, the country’s dependence on crude oil exports, limited industrial diversification and infrastructural deficiencies continue to constrain its trade potential. Addressing these challenges requires sustained investment in industrialisation, export diversification, human capital development and trade facilitation. Such measures would strengthen Nigeria’s capacity to better leverage opportunities under both the WTO framework and the AfCFTA.

Ultimately, the effectiveness of the GATT/WTO multilateral regime depends not only on the existence of international trade rules but also on developing economies’ capacity to participate meaningfully in the system and translate market access into sustainable economic development. For Nigeria, strengthening domestic institutions, improving competitiveness, diversifying exports and maintaining active engagement in international trade negotiations remain essential to maximising the benefits of the multilateral trading system.
