what is Foreign policy in which the U.S. supported other countries that promoted America’s diplomatic goals and business interests.
The foreign policy approach you're describing sounds like Dollar Diplomacy, although it could also refer generally to any foreign policy strategy that emphasizes supporting countries that align with US diplomatic and commercial interests.
Dollar Diplomacy was a term specifically used to describe the efforts of the United States, particularly during President William Howard Taft's administration (1909-1913), to further its aims in Latin America and East Asia through the use of economic power by guaranteeing loans made to foreign countries. The policy aimed to secure favorable treatment for US businesses abroad and to assert US economic, if not outright political, hegemony.
Under Dollar Diplomacy, the U.S. government attempted to protect and expand American investments and trade in these regions, promoting stability and order by ensuring that countries could repay their debts to U.S. financiers. This policy often emphasized substituting dollars for bullets, implying that economic leverage would be used rather than military intervention to influence other countries' policies and actions.
However, this strategy has a mixed legacy. It often led to resentment in the countries where it was applied and sometimes contributed to instability and anti-American sentiment when the economic interests served by the policy were perceived as benefiting the United States at the expense of the sovereignty and well-being of other nations.
In a broader sense, the US has pursued similar goals at various times in its history, supporting countries that embrace free-market economies, political systems that align with US democratic ideals, or strategic partnerships that enhance US security objectives. This approach has taken many forms, including foreign aid, economic partnerships, and strategic alliances.
