The Chinese use Pakistan as a cheap instrument to triangulate India between them. It is safer to presume that the Chinese now see Pakistan as an extension of their Western Theatre Command.

Why Shekar Gupta is worried about Chinese weapons when India won the war and Pakistan was humiliated? I mean his article soon after 10th may declared India clear victor. India intercepted all Fatah rockets but somehow Poonch was turned in to mini Gaza.
And no Shekar g, Pakistan didn't fire any cruise/ballistic missile. Maybe couple of CM400 from JF17 to hit S400 if you count that. Fatah are rockets, cannot call them missiles.
