Both sides, wary of the other and divided within, could not move forward until the verdict of Mao’s success was delivered. The Chinese leadership was still distrustful of American imperialism and hamstrung by its pro-Soviet faction. America’s leaders, skeptical over uncovering a new Tito, feared manipulation by Beijing and were concerned over the actions of the third very interested player, the Soviet Union.

Moscow, with good reason to fear another heretic, put extreme pressure on Mao to declare his solidarity. The Chinese communist leader, whose exact sentiments cannot be known, undoubtedly bristled at the Kremlin’s behavior, but he could not ignore Stalin’s stranglehold over Manchuria or his own ideological commitment to Marxist unity. On June 30, 1949, Mao announced that China was “Leaning to One Side” and intended to ally itself with “the Soviet Union, with the People’s Democracies, and with the proletariat and the broad masses of the people in all other countries and form an international united front.” One day later, Secretary of State Acheson vetoed Stuart’s trip to Beijing.

Once the PRC was established, Washington chose a pragmatic policy between the two extremes of open hostility and conciliation. Combining balance-of-power concerns, ideological aversion, and fears for the safety of Chiang’s exile government in Taiwan, the United States refused recognition of the PRC and blocked its seating in the United Nations, but Washington did not stop others from opening embassies in Beijing or from breaking relations with Chiang Kai-shek.

Nonetheless, the Chinese revolution (occurring soon after the explosion of the Soviet atomic bomb) intensified the Truman administration’s fears of communist expansion in Asia. Alarmed over the Vietnamese communist leader Ho Chi Minh’s February 1950 mission to Moscow, the Soviet decision to recognize his government, and Chinese support for the Viet Minh insurgency against French colonial rule, the United States swallowed its anti-imperialist sentiments and cast its lot with the Paris-backed puppet emperor Bao Dai.
