For a century China has been assaulted and dismembered by Western as well as Asian states. Still, a more effective military could be used for ill. And today the PLA's commercial operations divert attention from force modernization. The commercial empire takes military personnel far afield from military concerns. For instance, the PLA diverted production from weapons to export goods.
Soldiers hawk cosmetics rather than train to, say, invade Taiwan.
Profit-seeking has enmeshed top officers in a web of corruption. All told, the PLA is less effective because of its business activities. It should concentrate on national defense. Again, a more professional Chinese military doesn't mean war in Asia. Nevertheless, there is no reason to encourage Chinese military power.
