Chinese avoid mixing with Negroids, but they have no issue with mixing with Europeans (especially since Europeans are genetically recessive, so the kids will be intelligent but also look Chinese) and they especially favour Jews. The only reason they would be wary of consensual mixing is security reasons, not wanting spies to leak info to their enemies. [Mao's China has always had weird propaganda to show solidarity with Soviets/ Slavs. ](https://pic8.co/sh/xq52TA.jpg) Sorry for the crappy pic but you get the point. In turn, Russians are not bothered about mixing with East Asians since a considerable portion of their populace are already Eurasian. They may not like effeminate homosexual stuff being spread, but neither do the Chinese, they simply understand that shit will lead to societal breakdown. China and Russia are both rife with human trafficking, so I wouldn't be surprised if it was going on.
