Trade

Trade denotes the exchange of goods, services, capital, and increasingly data across borders, structured by a layered legal architecture descending from the General Agreement on Tariffs and Trade (GATT, 1947) to the World Trade Organization (WTO), established by the Marrakesh Agreement of 15 April 1994 and operational from 1 January 1995. The WTO's foundational disciplines are the Most-Favoured-Nation principle (GATT Article I), which forbids discrimination between trading partners, and National Treatment (GATT Article III), which bars discrimination against imports once they clear customs. Services are governed by the General Agreement on Trade in Services (GATS) and intellectual property by the TRIPS Agreement, both annexed to the Marrakesh package. The Doha Development Round, launched November 2001, remains substantively deadlocked as of 2026, pushing states toward regional and bilateral free-trade agreements (FTAs) and preferential arrangements outside the multilateral track.

Trade theory rests on classical foundations: Adam Smith's absolute advantage (1776) and David Ricardo's comparative advantage (1817), which holds that nations gain by specializing where their opportunity cost is lowest even when uncompetitive in absolute terms. The Heckscher–Ohlin model explains trade patterns through factor endowments. Instruments of trade policy include tariffs, quotas, anti-dumping and countervailing duties (WTO Anti-Dumping Agreement), subsidies, and non-tariff barriers such as sanitary and phytosanitary measures. The WTO's Dispute Settlement Body, with its Appellate Body, was the system's enforcement crown jewel until the Appellate Body became non-functional in December 2019 after the United States blocked appointments, leaving appeals into a legal void partly bridged by the Multi-Party Interim Appeal Arrangement (MPIA).

Concrete instances illustrate trade's geopolitical weight. China's WTO accession on 11 December 2001 reshaped global manufacturing and is central to the china-foreign-policy syllabus; Beijing's Belt and Road Initiative (2013) and the Regional Comprehensive Economic Partnership (RCEP, in force 1 January 2022) extended its trade reach. India joined RCEP negotiations but withdrew in November 2019 over fears of Chinese import surges and dairy-sector exposure. The US–China tariff war from 2018, the USMCA replacing NAFTA (in force 1 July 2020), and the post-Brexit UK–EU Trade and Cooperation Agreement (2021) are recurring case studies. India operates FTAs with ASEAN, the UAE (CEPA, 2022), and Australia (ECTA, 2022), while pursuing one with the EU.

For exam purposes, trade spans multiple papers. In UPSC, it appears in GS Paper II (international relations, India and its neighbourhood, bilateral and global groupings) and GS Paper III (Indian economy, external sector, balance of payments). FSOT and CSS test WTO architecture, FTA mechanics, and trade-war dynamics under economics and world affairs. The china-foreign-policy course probes Beijing's use of trade as statecraft. Typical question angles ask candidates to evaluate why India left RCEP, assess the WTO's relevance amid Appellate Body paralysis, distinguish comparative from absolute advantage, or analyse protectionism versus free trade. Master the named agreements, their entry-into-force dates, and the GATT article numbers — examiners reward precise citation over generalities.
