Here is a 1927 American magazine article that reported on the Soviet influence taking place in China. Attention is paid to the activities of a young Soviet named Karl Berngardovich Radek (born Karol Sobelsohn: 1885 - 1939; pictured above):
"Russia has been the only country to assist the Nationalist China movement to which they all hope to devote their lives. Men who believe in the 'dictatorship of the proletariat' have furnished much of the brain-power that has organized, directed and articulated the Chinese popular uprising in it's successful Northern drive...As far as foreign culture is concerned, China is still much more deeply steeped in American and British idealism than in those of modern Russia"
