Not for the Soviet Union. But he was actually a force for moderation vis-a-vis Mao; see Michael H. Sheng, *Battling Western Imperialism: Mao, Stalin, and the United States*
"Here , an old pattern in Mao - Stalin relations manifested itself again : Mao was more of a radical revolutionary inclined to simple solutions , while Stalin was more of a tactful statesman who tutored Mao to form a united front with the GMD during the anti-Japanese war, and he continued to correct Mao's radicalism. Had Stalin lived ten years longer , would Mao's Anti -Rightist movement and the Great Leap Forward have happened ? One might well argue that from a CCP retrospective , Stalin died too early and Mao lived too long." https://books.google.com/books?id=HZJcxq1DIOYC&pg=PA167

One interesting (to me, anyway) detail is that in the PRC the nominally multiparty system is the result of Stalin, who overruled Mao's suggestion that a one-party system be established following victory. See Stalin's telegram of April 20, 1948: "We are very grateful for the information from Comrade Mao Zedong. We agree with the assessment of the situation given by Comrade Mao Zedong. We have doubts only about one point in the letter, where it is said that “In the period of the final victory of the Chinese Revolution, following the example of the USSR and Yugoslavia, all political parties except the CCP should leave the political scene, which will significantly strengthen the Chinese Revolution.” We do not agree with this. We think that the various opposition parties in China which are representing the middle strata of the Chinese population and are opposing the Guomindang clique will exist for a long time. And the CCP will have to involve them in cooperation against the Chinese reactionary forces and imperialist powers, while keeping hegemony, i.e., the leading position, in its hands. It is possible that some representatives of these parties will have to be included into the Chinese people's democratic government and the government itself has to be proclaimed a coalition government in order to widen the basis of this government among the population and to isolate imperialists and their Guomindang agents. It is necessary to keep in mind that the Chinese government in its policy will be a national revolutionary-democratic government, not a communist one, after the victory of the People's Liberation Armies of China, at any rate in the period immediately after the victory, the length of which is difficult to define now. This means that nationalization of all land and abolition of private ownership of land, confiscation of the property of all industrial and trade bourgeoisie from petty to big, confiscation of property belonging not only to big landowners but to middle and small holders exploiting hired labor, will not be fulfilled for the present. These reforms have to wait for some time. It has to be said for your information that there are other parties in Yugoslavia besides the communists which form part of the People's Front."
