How did Taft's policy in Latin America differ from Roosevelt's approach

The answer is:

Roosevelt's policy was created with the aim of expanding the US form of better living to different parts of the world. Roosevelt wanted the other counties to see The United States as a country that promotes progress so that, the US government could intervene in that country.

On the other hand, Taft's policy wanted to invest in other countries by spreading American actions. The US would invest in Latin American countries and intervene only when it shows up that American investments were at risk as a result of political instability in these countries. (This was known as dollar diplomacy)

Both Roosevelt and Taft wanted The United States to increase its influence and engagement throughout the world but both in different ways.
