In order to keep the Sino-Soviet relations close, the new China that has just been established for less than three months has been decided by the Central Party Committee of the CPC Central Committee and led by a delegation headed by Mao himself. This is the first visit of the new Chinese leader and the first time that Mao Zedong went abroad.
