Which factor is least likely to affect international trade?

Company advertising strategies are least likely to affect international trade when compared to the other factors listed. This is because international trade is primarily influenced by broader macroeconomic and regulatory factors rather than specific marketing approaches.

Legal and regulatory forces establish the framework within which trade occurs, governing tariffs, trade agreements, and compliance requirements that can either facilitate or hinder international transactions. Geographical location plays a crucial role as it determines shipping routes, transportation costs, and market accessibility. Economic and financial forces, such as exchange rates and economic stability, directly influence trade dynamics by affecting the pricing and competitiveness of goods and services across borders.

While advertising strategies can enhance a company's visibility and appeal in international markets, they are generally secondary to these foundational factors that shape the structure and viability of trade itself. Therefore, in the context of determining what has the least impact on the broader scope of international trade, company advertising strategies stand out as the least significant factor.
