Import: Imports refer to goods or services purchased by one country from another. They help satisfy domestic demand for items not produced domestically or obtained at lower costs abroad.
Export: Exports are goods or services produced domestically that are sold to other countries. They allow countries to earn revenue, create jobs, and stimulate economic growth.
Balance of Trade: The balance of trade is the difference between a country's exports and imports. A positive balance of trade occurs when a country exports more than it imports, while a negative balance indicates higher imports than exports.
