I think for the PLA, 99s and 96s especially, are for homeland defence. The new 15s are meant for rapid reaction forces, and increasingly, overseas expeditionary force deployments as they are light enough to airlift in numbers rapidly, and will be much less restricted by local infrastructure and geography than western heavyweights. For deployments where they might have to face off against enemy heavyweight MBTs, they would be supplemented by 99s.
