It's true, but Sino-Soviet relationships was already recovering by the time he was in charge. Plus collapse of Soviet Union has a lot of negative on China too. Overall I say jury is still out if you look at it from purely Chinese perspective and definitely way negative from Russian perspective.By popping the Soviet Union he not only destroyed the only major threat bordering China but helped boost Chinese military tech by several decades in one fell swoop. He accomplished a lot for China.
Hell once upon a time Ukraine could build things like Varyag and An-225, now they're down to exporting wheat and women.
