莫斯科中山大学
In November 1925, the CPC sent Wang to Moscow Sun Yat-sen University in Russia. During this time, Wang mastered both the Russian language and Marxist–Leninist theory, becoming known by the Russian name Ivan Andreevich Golubev () or simply Golubev. It was also during this time that Wang encountered his first major political adversary, Ren Zhuoxuan. Ren was appointed as the secretary of the University's student CPC branch. Eventually Wang's eloquence won over Ren's authoritarian style in various debates. Consequently, in April 1926, Wang was elected as chairman of the University's CPC branch. After the election, Pavel Mif, the University's vice president, became fond of Wang. In January 1927, when Mif came to China as the head of a Soviet delegation, Wang was his interpreter.
