World trade has significant implications for multinational enterprises (MNEs) and smaller companies. It provides opportunities for market expansion but also political, economic, and cultural challenges. MNEs must consider factors like local product regulations, profit regulations, cultural differences, and economic conditions when operating in foreign countries. Smaller companies also face these challenges when engaging in world trade and must strategically consider issues like local infrastructure and taxation policies. Cultural differences especially impact how MNEs structure relationships between headquarters and subsidiaries.
