This plane is for the protection of Chinese territories and trading links.
This shows the Chinese can now master major technologies.
The export of this plane in the future may mean a lot of money.
All of the above means a lot of $$$ to be made for China and this is good for the Chinese people.
Just think about it, rather than bashing for no reason at all.
You are right. We can see the traitors want to sellout to the European imperialists. Therefore they want to see China militarily weak, so that the western powers can invade China again.
The export of this Chinese plane in the future may mean a lot of money. Probably worth US$30 million each plane. Lots of hightech jobs will be created in the Chinese plane making industry.
