Under the name of Dollar Diplomacy the Taft administration engineered such a policy in Nicaragua. It supported the overthrow of José Santos Zelaya and set up Adolfo Díaz in his place, it established a collector of customs, and it guaranteed loans to the Nicaraguan government. The resentment of the Nicaraguan people, however, eventually resulted in U.S. military intervention as well.

Taft and Knox also attempted to promulgate Dollar Diplomacy in China, where it was even less successful, both in terms of U.S. ability to supply loans and in terms of world reaction. The dismal failure of Dollar Diplomacy—from its simplistic assessment of social unrest to its formulaic application—caused the Taft administration to finally abandon the policy in 1912. The following year President Woodrow Wilson (Wilson, Woodrow) publicly repudiated Dollar Diplomacy, though he acted as vigorously as had his predecessors to maintain U.S. supremacy in Central America and the Caribbean.

Dollar diplomacy has come to refer in a disparaging way to the heedless manipulation of foreign affairs for strictly monetary ends.
