Precisely the plan, IMO.
Not exactly the plan if they've been reducing the size of their Army, which they have.
One additional problem they have is quite a few soldiers and Officers that have been RIFed as part of that reduction in total troop strength; granted, they're the less competent ones, but they do have a modicum of military training, and many are both unemployed and pissed off. That's never a good recipe.
I heard a discussion recently in which it was pointed out that all those one-child sons and grandsons will soon be the sole support for aging parents and grandparents. In other words, China has turned the natural order of things topsy-turvy.
With China's obsession now in creating economic wealth, the nation may not be able to send those one-sons to war.
Think about it.
