The World Trade Organization (WTO) is the international organization whose primary objective is to open up trade for the good of all. A series of course modules intended to serve as educational materials that can help lawyers, civil servants, academics and business people in developing countries understand the basic rules and jurisprudence on dispute resolution in the field of international trade, investment and intellectual property. Their growth, expansion and deepening have been remarkable since the 1990s and go beyond traditional trade liberalization, which goes beyond WTO rules on issues such as services, investment, competition, the public procurement environment and labour. Ensure consistency between negotiations on various agreements, including the interface with multilateral rules. discussions on the formulation and implementation of trade policy, particularly in the context of WTO accession negotiations. In this context, UNCTAD is working to strengthen the capacity of developing countries to participate effectively in multilateral, regional and bilateral trade negotiations and to maximize the use of trade agreements to achieve development outcomes. The international trading system comprises several thousand unilateral, bilateral, regional and multilateral rules and agreements between more than two hundred nations. Discussions focused on trends in trade flows, both for goods and services, and on various factors that influence international trade patterns, including multilateral and regional trading systems and their link to national policies. Successful management of this complex and rapidly evolving mass of political and economic agreements requires understanding global changes, understanding the effects of trade on national development interests and priorities, and promoting consensus on removing barriers to trade and a commitment to more open and equitable international trade. In response to this mandate, the Trade and Development Council examined trends in international trade in goods and services and trade policy. raise awareness among the negotiating team and other government agencies, the private sector and science, as well as key policy makers, including parliamentarians on the GATT and WTO agreements, the accession process, the obligations and benefits of WTO membership. Given the lack of resources, expertise, institutional and regulatory framework for trade and WTO issues in most of the candidate countries, support for the capacity building of candidate countries is therefore an essential element in efforts to address their accession process.
