How did the Chinese view the Soviets during the Cold War?

The cause of the firefight between Soviet and Chinese troops was a matter of dispute. The Soviets charged that Chinese soldiers crossed the border between the two nations and attacked a Soviet outpost, killing and wounding a number of Russian guards. The intruders were then driven back with heavy casualties. The Chinese report indicated that it was the Soviets who crossed the border and were repulsed. Either way, it was the first time that either side openly admitted to a clash of arms along the border, though it had been rumored for years that similar run-ins were occurring. Ever since the early-1960s, relations between the two communist superpowers had deteriorated. China charged that the Soviet leadership was deviating from the pure path of Marxism, and by the mid-1960s, Chinese leaders were openly declaring that the United States and the Soviet Union were conspiring against the Chinese Revolution.

Explanation:

basically China crossed the border to attack and killed a number of soviets, then later on accused the Soviets of crossing the border and attacking them so ever since they always basically hated eachother.
