I don't want to sound rude, but neither India nor Pakistan has a history of being able expand infrastructure in a massive way.
The is the same argument of SCS all over again, we don't built and build fast because we are aggresive, we are jus so much better and richer than you guys are. This applies to all manners of infrastructure all over China and the world.
if this the only road china is building and this quickly, that would support your argument, but based on Chinas history, it is nothing out of the ordinary.
This is exactly why we are better, we don't need your stats to be fake, we don't need your army to be weak, we don't need your country to be in anarchy. No matter how good you think you are we are just that much better.
