Trade agreements refer to formal or informal arrangements between two or more countries, aimed at facilitating and promoting trade between them. These agreements can cover a wide range of issues such as tariffs, quotas, subsidies, intellectual property rights, investment, and services. The main objective is to reduce barriers to trade, increase market access for goods and services, and promote economic growth through international cooperation. Trade agreements are negotiated by governments or trading partnerships, and they can be bilateral (between two countries), regional (involving multiple countries in a region) or multilateral (involving many countries from different regions). Examples of trade agreements include NAFTA (North American Free Trade Agreement), TPP (Trans-Pacific Partnership), and CETA (Comprehensive Economic and Trade Agreement).
