A few observations. Indians and Pakistanis generally tend to meet up in some third country, and when they meet up, there is no such animosity as would be on these forums. The only two things that both sides don't give up on is Kashmir and cricket, and if ever these topics come up for discussion, though a rarity, surprise surprise, people tend to be very cordial, and logical, but then no one is ready to budge as well. Other than that, it's good fun, and like any other "desi", both these nationalities mix up well, and are by and large on good terms.
One thing I have noticed, irrespective of how much love Pakistanis have for China, it is either the average Chinese isn't aware of such a love and friendship, or they just want to keep a distance, whatever it might be, but one will never really find these two nationals interacting much, nor sharing any such relationship as is talked about through the media by the leadership of the two countries. It seems all the friendship talk is limited at the government level, to Pakistanis at large, and members from two countries on various forums, but certainly not reciprocated by Chinese people at large.
