Secure in its relations with Moscow, the Mongolian government shifted to postwar development, focusing on civilian enterprise. Mongolia was at this time one of the world's most isolated countries, having almost no contact with any nation outside of the Soviet Union. After the war, international ties were expanded and Mongolia established relations with North Korea and the new Communist states in Eastern Europe. Mongolia and the People's Republic of China (PRC) recognized each other in 1949, and the PRC relinquished all claims to Outer Mongolia. However, Mao Zedong privately hoped for Mongolia's reintegration with China. He raised this question before the Soviet leadership as early as 1949 (in meeting with Anastas Mikoyan at Xibaipo), and then, after having been firmly rebuffed by Stalin, again in 1954, a year after Stalin's death. In 1956, following Nikita Khrushchev's denunciation of Stalin, the Chinese leaders attempted to present Mongolia's independence as one of Stalin's mistakes in meetings with Mikoyan. The Soviet response was that the Mongols were free to decide their own fate.
