Free trade allows nations to exchange goods and services without tariffs, duties, or quotas. This system enables countries to focus on producing their specialties—goods they excel at making—and use the revenue from exports to purchase needed products from others. For instance, a country specializing in beef can trade with another excelling in electronics under a free trade agreement by reducing tariffs for mutual benefit. While some governments restrict free trade temporarily to protect local industries and jobs, it generally boosts economic growth by maximizing competitive advantages. Nations like China and India experienced rapid expansion after adopting these principles; organizations like the World Trade Organization work towards ensuring smooth global trading practices.
