International business involves creating, shipping, and selling goods and services across national borders. It provides benefits like access to raw materials and parts, global opportunities, and improved political relations. International trade includes imports, which are products bought from other countries, and exports, which are products sold to other countries. However, trade barriers like tariffs, quotas, and embargoes can impact international business. The key factors of the international business environment are geographic conditions, culture and social factors, political and legal systems, and economic conditions in different countries.
