Yes, Moa Zedong and the Communist Party of China was successful in liberating china and laying the basis for its current success:

1. after the death of Sun Yat-Sen in 1925, the Guomindang was headed by Chiang-Kai-Shek. Though he strengthens the rule of Guomindang yet he took no step to achieve the three revolutionary objects of Sun Yat-Sen. Contrary to it, he followed the policy to suppress his opponents and the communist. He was also supported by the Soviet Union. Moreover he attempted to raise a new class of landlords, he exploited the peasantry. In the mean time communist leader Moa-Zedong form the red army to strengthen the peasant movement.

2. In 1930 Mao Zedong became the chairperson of the council of presents and workers and began to work underground. He established the red army and started a guerrilla war against Chiang-Kai-Shek’s large army. He defeated Chiang’s army four times, but in fifth attack he was so under pressure that he planned and implemented the long march.

3. In 1935 Mao Zedong formed a communist front against Japan. He thought that his struggle against Japan would popularise him and also make his mass movement more effective. He also suggested that the Guomindang should work with the red army and a united front be formed. But Chiang did not accept his proposal. This harmed his prestige to the extent that his own soldiers imprisoned him. Moa continued his struggle against Japan until he succeeded.

4. Chiang-Kei-Shek was worried about increasing power of Mao Zedong. He did not want to work with him. After great difficulties He was ready to stand against Japan. When the war ended, Moa put a proposal of a coalition government before Chiang but he did not accept it. Mao continued with his struggle. In 1949 Chiang escaped to Formosa (Modern Taiwan) to seek asylum there. Mao Zedong was elected the chairman of the Chinese government. He held his office till his death.
