About China, China is the largest fund provider of all welfare projects(basically very low return) in Pakistan, Highways, Bridges, Port, Dams, Hydro-Power, and technological aid for you know what, etc. This is the best way they can do to benefit average people, instead of corrupted officials.

China's aid could be much more if all classified info exposed, if we are in a right track towards national prosperity, and if we have less Pro-US ambiguous and corrupted officials.
