Trade agreements are formal agreements between two or more countries or regions that facilitate the exchange of goods and services. These agreements typically cover areas such as tariffs, quotas, and regulations that affect trade between the signatories. Trade agreements can help to increase trade volumes, reduce barriers to trade, and promote economic growth by providing a framework for cooperation and harmonization of trade policies. Examples of trade agreements include the North American Free Trade Agreement (NAFTA), the European Union's single market, and the World Trade Organization's agreements on trade in goods and services. Trade agreements can have a significant impact on the economies of the countries involved, as well as on consumers and businesses operating in those countries.
