**Introduction** The participation of small and developing countries in the World Trade Organization (WTO) is shaped by binding legal commitments that apply to all members, but also by differences in administrative capacity, economic structure, negotiating leverage, and access to development flexibilities. These factors influence both compliance with WTO rules and the extent to which members engage actively in committees, negotiations, monitoring processes, and dispute settlement. **Key structural and institutional drivers** **1.** **Administrative and legal capacity** WTO membership entails implementation of agreements across goods, services, and intellectual property, as well as procedural obligations such as submitting regular notifications. Many developing members face difficulties in meeting notification requirements, particularly in technically demanding areas such as subsidies and agriculture. WTO reporting has consistently noted uneven notification performance across the membership, reflecting capacity constraints in some economies rather than systematic non-compliance[1]. Institutional capacity also affects participation in dispute settlement. Although all members have equal legal standing, dispute proceedings require sustained legal expertise, financial resources, and familiarity with WTO procedures. Dispute participation data show that cases are concentrated among a relatively small number of members with stronger legal infrastructure and greater financial capacity[2]. For smaller administrations, limited resources can restrict both offensive and defensive use of the system. **2.** **Economic structure and trade exposure** The structure of a country’s economy and its reliance on external markets shape its priorities within the WTO. Economies that depend heavily on exports — particularly where exports are concentrated in a small number of sectors — place significant importance on predictable “most-favored-nation” (MFN) treatment and binding tariff commitments. Stable market access conditions are directly linked to growth performance and macroeconomic stability in such cases[3]. When trade restrictions increase globally, export-dependent developing economies are especially vulnerable. WTO trade monitoring reports document a sustained rise in trade-restrictive measures in recent years, underscoring the importance of transparency and multilateral oversight for members seeking to safeguard market access[4]. For small economies with limited diversification, preserving open and non-discriminatory trade conditions remains a central objective of WTO engagement. **3.** **Special and differential treatment** Special and differential treatment (SDT) provisions are embedded in multiple WTO agreements and provide developing and least-developed members with longer implementation periods, technical assistance, and, in certain areas, differentiated obligations[5]. These flexibilities shape how governments sequence domestic reforms and address administrative capacity constraints. Extended transition periods, for example, allow for gradual regulatory adjustments and institutional strengthening. Debates over differentiation among developing members have become more prominent in recent reform discussions. Questions concerning eligibility and the scope of SDT influence negotiating dynamics and coalition strategies. The institutional and development challenges facing developing countries in this context are well documented in analyses of their participation and constraints within the WTO framework[6]. **4.** **Coalition-building and collective engagement** In a consensus-based system, coalition-building is an important strategy for small and developing countries. Groups such as the G90 and the African Group enable members to coordinate positions and increase bargaining leverage.[7] Acting collectively enhances negotiating influence and allows members to share the technical workload associated with drafting proposals and responding to negotiating texts. Coalitions also provide a forum for exchanging expertise and aligning positions across different negotiating areas. This collective approach strengthens the visibility of development-related concerns and supports more consistent engagement in committee discussions. **5. Technical assistance and Aid for Trade** Capacity-building initiatives, including Aid for Trade, strengthen participation. Aid for Trade programs support trade-related infrastructure, customs modernization, regulatory reform, and standards compliance. These improvements enhance the ability of developing economies to implement WTO commitments and integrate more effectively into global markets[8]. Stronger domestic trade institutions improve the quality and timeliness of notifications, support more informed engagement in negotiations, and increase the benefits derived from WTO membership. **Conclusion** Small and developing countries participate in the WTO under a common legal framework, but their engagement is shaped by differing institutional capacities and economic conditions. Administrative resources, export structure, trade exposure, development flexibilities, coalition strategies, and access to technical assistance influence both compliance with formal obligations and day-to-day participation in WTO processes. Strengthening institutional capacity and preserving balanced development considerations remain essential to ensuring inclusive and effective engagement across the membership.
