Mao Zedong
A few years after Mao won the civil war in China, Nikita Khrushchev became the leader in the Soviet Union. Before this, Joseph Stalin was the leader in the Soviet Union. Mao liked Stalin and respected the way he led. China and the Soviet Union became allies with each other. Khrushchev thought Stalin was a criminal dictator, and led the country very differently. Mao and Khrushchev did not like each other, so the Soviet Union was no longer allies with China. China now had only a few allies like Albania, North Korea, Democratic Kampuchea, and Pakistan. This change of friends was called the Sino-Soviet split. "Sino" is another way to say "Chinese".
