So you want to say Pakistan and China have bad relationship?
Only in indian wet dreams, 
China and Iran never accused Pakistan of terrorism, they merely asked Pakistan to stop terrorists to enter their territory from Afghanistan via Balochistan and FATA (trained by, guess who?).
Know the difference?
Now the evidence for indian terrorist training activities in Afghanistan is so huge that even your allies like americans are asking you to keep it low.
The problem with you indians is that you believe all the bull$hit your media feeds you. And you actually believe that india is not training likes of BLA, TTP etc.
Even though your Rahul Gandhi says that you should ignore Pakistan, you still can not leave us alone in peace, this is your nature!
A proof is you and loads of your indian friends being on a Pakistani board here, LOL. Accept the fact, despite your huge population, you always think small!
This is the difference between you and China… !
