What is the primary focus of international business?

The primary focus of international business is conducting commerce across national borders. This encompasses a wide range of activities including importing, exporting, foreign investment, and engaging in various forms of trade between countries. International business aims to leverage opportunities in different markets, managing operations and strategies that consider cultural, economic, legal, and political differences across nations. This focus allows businesses to expand their reach, enhance profitability, and diversify their operations by accessing resources, markets, and labor that may not be available domestically.

The other options do not align with the fundamental goals of international business. Maximizing domestic market shares primarily concerns local operations and does not consider the global market landscape. Reducing global competition suggests a defensive strategy, which doesn't reflect the proactive nature of international business that seeks to thrive in competitive environments across borders. Establishing local markets only ignores the broader perspective of engaging with international markets and developing global strategies that capitalize on opportunities outside a company's home country.
