Trade means the voluntary exchange of goods and services. It can be conducted at two levels: national and international. International trade is the exchange of goods and services among countries across national boundaries.
Balance of Trade records the volume of goods and services imported and exported by a country.
Free Trade (or trade liberalisation) is the act of opening up economies by reducing trade barriers like tariffs. However, it can lead to dumping.
Dumping: The practice of selling a commodity in two countries at a price that differs for reasons not related to costs, which can harm domestic producers.
Originally established as GATT (General Agreement on Tariffs and Trade) in 1948, it was transformed into the World Trade Organisation (WTO) on January 1, 1995.
Formed to encourage trade among countries with geographical proximity and complementarities. Today, 120 regional trade blocs generate 52% of world trade.
Ports are the chief gateways of international trade, providing facilities for docking, loading, unloading, and cargo storage.
