Forgive me I'm rusty on Indochina but you would discuss what communism has done to Vietnamese/Cambodian society. Impacts generally refer to politics, the economy, the society, the military, all that jazz. Discuss what has the transition to communism done to the respective nations. Look the key issues specially the rise of communism as well as te respective dot points that relate to communism. Good Luck buddy sorry I couldn't go into detail I havent looked at Indochina in so long imao
