In Stalin’s view, Mao was useful because he would help spread communism across Asia. So, in February 1950, the two leaders signed the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance. Mao wanted more — security guarantees against the United States and direct military backing — but Stalin was “noncommittal”. In his view, Mao was not only beneath him — a needy neighbour with delusions of grandeur — but also a liability. Closer ties with the PRC, he feared, could jeopardise the Soviet Union’s gains in Asia and lead to US intervention.
Today, it is Chinese President Xi Jinping who is looking down on his Russian counterpart, Vladimir Putin. In fact, Putin’s state visit to Beijing earlier this month — his first trip abroad since being inaugurated for a fifth term — was practically a mirror image of the Stalin-Mao encounter 75 years ago.
