Because it is the Chinese govt's responsibility to arrest all the Norinco leaders and execute them, as is the norm in China. Hell, they can at least start an official investigation. Nornico supplying arms illegally to acknowledged terrorist groups while the Chinese govt looks the other way is what's the problem here.
No, Nornico didn't supply arms to any acknowledged terrorist groups, or even any india. The customer they sold the weapon to is Willy, remember? Unless India security department shows any possible evidence that Nornico got involved DIRECTLY, Chinese gov can't do anything to Norinico since they were selling weapons to a Thai citizen.
This is no different from what Pakistan does and you clearly know where's Pakistan's reputation today.
Oh, please don't get Pakistan involved here. The whole world has different opinion of where is Pakistan's reputation today. From US to France, everyone is selling weapons to them as long as they can pay it with cash.
You think there is a single company in China that will go against CCP? You don't know your own country.
Why CCP should have any will on this? There is no India security staff coming to them with this case. If India security department doesn't bother to ask, why Chinese is bothered to do anything about it?
Bangladesh executed 14 terrorist leaders for smuggling Chinese made arms from Norinco (named by the judge) while the actual culprits are sitting in Beijing. Bangladesh is a democratic country. They won't simply execute 14 people for no reason.
Still, you have the same problem here: why don't raise the issue to Chinese gov if you have any evidence?
