PLAN will most definitely increase its presence and activity in South Asia. China and Pakistan alliance is strengthening to counter Indian thuggery and the more aggressive India gets the more China will get involved in South Asia. Not only will PLAN increase its presence and turn Gwadar into full naval base but China will sell weapons to Pakistan so PLAN and the Pakistan military will keep the fake country firmly in check.
The massive naval buildup in China is not just aimed at SCS because the SCS is already packed with Chinese naval vessels.
If India tries again to be aggressive to China you will face a worse humiliation than you got in 1962. The more belligerent the Hindu radicals get towards peaceful countries like Pakistan, the more you will have to deal with China.
China will not only increase its military presence around India but China will fund and arm the many separatist movements inside your fake country to cause problems for your regime both internally and externally. Pakistan will also be of great help in this regard to destabilise India and collapse it into many different countries like what happened to Yugoslavia. Whatever problems you can cause China, China will return the favour in much bigger dosages.
To be a failed state, 50% of the country must lack basic sanitation. Guess which country qualifies for that?
