i have two officers known to me currently undergoing mil training in China, checked from both of them, they dont recall meeting a (very) enthusiastic Chinese on the Subway 
Anyways, i have requested them to keep their radars up, in case they meet other Pakistani Officers there, they will throw a test call to them.
Best of luck!
