What's the Cause of the Sino Soviet Split?

A lot of the early left wing resistance to the soviet regime came from rural areas. Is it kind of a desire to to avoid developing these places that are less controllable? The party just isn't interested in in rural development, because they want to be able to develop militory power and heavy industry. This is one of the reasons for the sino soviet split. And when entire rural party is dead, it's like wioke. So now we have a peasant base.
