NAFTA was aimed at improving trade relations among which countries?

The North American Free Trade Agreement (NAFTA) was specifically designed to promote trade and economic cooperation among Canada, Mexico, and the United States. By eliminating trade barriers such as tariffs and facilitating a freer flow of goods, services, and investments among these three countries, NAFTA aimed to enhance economic collaboration and boost each participating country's economic growth. The agreement, which came into effect in 1994, created one of the largest free-trade zones in the world, fostering increased trade among the three nations. This historically significant pact emphasized the interconnectedness of these economies and set the stage for further trade agreements in the region.

The other combinations mentioned do not reflect the countries that were participants in NAFTA, thus highlighting the importance of identifying the correct trio of nations that were directly involved in this trade agreement.
