Hitler wanted the Japanese to invade Siberia.
But the Japanese had already had a couple of go-rounds with Soviets at Lake Khasan and Khalkhin Gol and did not want any more of that.
That freed up the Soviet forces in Siberia to fight the Germans and probably changed the outcome of WWII.

Yep, they went up against a General named "Zhukov".
