Answer:
To encourage other nations to become communist.
Step-by-step explanation:
The Communist International (Comintern) was an international organization that wanted to implement communism all over the world. The main purpose of the organization, therefore, was to encourage as many nations as possible to become communist. The Comintern was active from 1919 to 1943. It was eventually dissolved by Stalin to avoid antagonizing the United Kingdom and the United States.
