If the Nazi win and seize most of Conteinental Europe up to the Urals, while Mao wins the Chinese civil war as per OTL, how would rump USSR and PRC get along? The USSR would still be technologically more advanced, but being in a much weaker position, would it be much more dependent on China than the other way IOTL? Could we see a situation in which the USSR provides generous technology transfers to China in return for Chinese aid, allowing the PRC to technologically progress faster than IOTL?
