which of the areas had heavy communist influence after it gained independence?

Area 2

Explanation:

After the gaining of independence, the area that had big communist influence was the area marked with the number 2, or in that period called French Indochina. From this area, three countries emerged, Vietnam, Cambodia, and Laos. All three had communist movements, and in all three they became the dominant political forces. In Vietnam this led to a war with the United States, as the United States were not looking very fondly at the spread of communism. In Cambodia it led to one of the biggest massacres while Pohl Pot was in charge, while In Laos it meant stagnation, isolation, and poverty.
