Between Russia and China
As part of the Yalta Conference agreements, a plebiscite was held in Mongolia in October 1945 under United Nations (UN) auspices, with the vote overwhelmingly in favour of independence over autonomy. The Republic of China recognized Mongolia in January 1946, and the two countries signed a friendship treaty in February. In June 1946 Mongolia made the first of several unsuccessful applications to join the UN. Meanwhile, Mongolia recognized the People’s Republic of China on the latter’s proclamation in 1949 and established diplomatic relations with North Korea (1948), the Soviet satellite countries of eastern and central Europe (1950), and India (1955). Mongolia gained admission to the UN in 1961, and in 1963 the United Kingdom became the first Western country to establish relations with Mongolia.
The 1950s were a time of political transition and economic advancement. Choibalsan died in 1952 in a Moscow hospital, and Tsedenbal was appointed chairman (i.e., the equivalent of prime minister) of the Council of Ministers, (the highest organ of executive power. In 1954 MPRP General Secretary Tsedenbal was ousted by Dashiin Damba, who was designated MPRP first secretary, but in 1958 Tsedenbal retook control of the party—also as first secretary—and had Damba dismissed on ideological grounds. The collectivization of livestock herding was completed in the 1950s, as the herders were obliged to hand over all but a few of their animals to the large cooperative farms (negdel). The Trans-Mongolian Railway—jointly built by the Mongolians and Soviets and completed in 1955—spanned Mongolia from north to south and served as a symbol of Soviet-Chinese solidarity, but it was built using the Soviet broad rail gauge rather than the standard gauge used in China. In 1958 Mongolia began attending Comecon meetings, joining that organization in 1962.
Mongolia and China signed a treaty of friendship and mutual assistance in 1960, and the two countries amicably redemarcated the long frontier between them. However, the ideological dispute that developed between the Soviet Union and China over the unity and leadership of the communist movement soured Mongolia’s relations with China. China sharply criticized the Soviets for their handling of the October 1962 Cuban missile crisis with the United States and two years later conducted its first atomic bomb test—the prevailing winds carrying radioactive fallout northward into Mongolian territory. In January 1966 Mongolia and the Soviet Union signed a new treaty of friendship, cooperation, and mutual assistance that included secret protocols allowing the Soviets to station troops, aircraft, and missiles in Mongolia. Sino-Soviet relations degenerated further following clashes between their troops along their border at the Ussuri (Wusuli) River in March 1969. Meanwhile, Chinese leader Mao Zedong had launched the movement that became known as the Cultural Revolution (1966–76), during which the Mongols of Inner Mongolia in particular suffered considerably.
In 1949 the MPRP had condemned how Mongolian history was being taught, claiming that those with “bourgeois nationalist” views were extolling Genghis Khan’s conquests and Mongolia’s “feudal” past at the expense of the achievements of the party and the Mongolian revolution. Nonetheless, as the 800th anniversary of Genghis Khan’s birth approached in 1962, the party decided to organize celebrations honouring it that were to include unveiling a new monument to him, delivering speeches, and issuing a set of commemorative postage stamps. However, following Soviet criticisms that labeled Genghis a “reactionary” whose “Tatar-Mongol yoke” had laid waste to Russia, Mongolia quickly canceled the celebrations and withdrew the stamps. There followed a fresh MPRP evaluation of Genghis Khan, which also deemed him a reactionary and which credited him only for unifying the Mongol tribes. Any deviation from that line was considered unwanted promotion of nationalism and was not tolerated. This policy stifled virtually all discussion of Genghis Khan and Mongol nationalism for the next 40 years.
Tensions between Mongolia and China escalated throughout the 1970s. Mongolia accused China of wanting to annex Mongolia and, as a pretext for its territorial claims on Mongolian territory, of promoting Genghis Khan as a Yuan dynasty emperor. China, during its own 800th anniversary celebrations, countered by criticizing the Soviet Union for “occupying” Mongolia by stationing troops and military equipment there. In April 1978 China called for the Soviet withdrawal from Mongolia, and Premier Tsedenbal promptly visited a Soviet army unit stationed in Mongolia to thank it for protecting the country against the Chinese “threat.” Mongolia began expelling Chinese immigrants in early 1979, accusing them of “expansionist plots,” which further exacerbated distrust between the two countries. Tensions in the region eased considerably in the mid-1980s as Soviet and Mongolian leaders took steps to normalize relations with China. Diplomatic relations were restored between Mongolia and China in 1986.
