A trade bloc is a group of countries that come together to promote trade and economic cooperation among themselves. These countries often reduce or eliminate tariffs and other trade barriers, making it easier for them to exchange goods and services. Examples of trade blocs include the European Union (EU) and the North American Free Trade Agreement (NAFTA). Trade blocs can enhance economic growth by creating larger markets and increasing competition. They also allow member countries to negotiate trade agreements as a collective entity, which can strengthen their bargaining power on the global stage.
