Won't change much. The strategic depth is too less, and our backs are touching the Siachen glacier. The only thing that might save it is an investment in heavy tanks (which can beat Type-99s) in both quality and quantity, as well as attack helicopters and UCAV.
Ladakh is not a populated area, so no chance of urban and guerrilla warfare. Tanks, attack helicopters, and UCAVs will be the decisive factor.
Our "official" cyber warfare dept. is weak compared to China, which employs state-sponsored hackers and cyber-force. Whereas our open-source and independent hacker teams are much, much more powerful than Chinese teams. We are comparable, maybe even equal to the American cyber vigilantes.
For example, our OSINT dis-information group/propaganda group is much more active and effective than state-sponsored ones. You get what I am trying to say
Offense is the best defense
