Even Taiwan had to bow down to Beijing when it reelected its pro-China (anti-independence) party for president. Not only Tajikstan bows down. india will gets its turn too.
China is building railways to Pakistan and Nepal, where we can deploy main battle tanks directly to the subcontinent plains in wartime. From ports in Pakistan, Sri Lanka and Myanmar, we will eventually contest indian navy and bottle it up to a coast guard. You might even lose Andaman Islands. Meanwhile, we built forward airbases all along Tibetan border for air strikes and equipped them with our top
J-10B fighters.
The next war will be india's 1971, when india will be split into west india and east india (Assam, Manipur). Maybe more. I actually prefer this outcome to any peace deal with india, because even with a peace deal and return of Tawang a single big india will pose problems to its neighbors again a decade later. We can't leave india in one big piece.
