also cyber can allow steal of enemy information. a very useful thing to gather intel and even research without doing it yourself
and like others said up there, crippling opponents' information network and system will turn them into sitting ducks for Chinese plans
Indeed... but it is also not very wise to steal every bit of information. Because the information that one steal, might also be wrong or purposely put there as a way of sabotage.
Thus I believe the main focus on cyber was to improve on the nation's overall information network.
Another thing I could think of is China to launch more satellites and to finally complete her Beidou system. This would give them a much needed guidance system for their missiles and also improve on their conventional units such as their infantries, armoured, tanks and special force.
The future of China's military system would be to have a smooth system to link all the service arms together in one big integrated package. So the forces in frontline would be link directly to supporting elements from the rear.
All these required a larger number of satellites, UAV, AWAC, etc.
