You have little idea about what you're talking about. NDRC chair spoke to COAS, the day before. And this has not happened ever. =)China does not comment on the internal affairs of Allies such as Pakistan it's strictly enforced within their Foreign ministry so i would not expect any statement as such. But rest assured seeing IK go will put a smile on China's face contrary to what people here are blabbering about.
Now go talk to your sources and see what they can possibly share with you.
Enjoy!
