Why keep on fighting instead of spending money on education, housing, environment protection, development and so on.
I hope Vietnam be China's best friend, we look exactly the same, similar culture and political ideology and shared memory.
No more fighting, no need. Human should be smarter than animals, we should resolve issues by talking instead of fighting.
I go to a Pho restaurant near my home weekly, and have haircut by a Vietnamese uncle monthly. I never had any issues with them in person.
The Vietnamese uncle give me a cigarette for free when I went to his shop every time, although I had quit smoking for many years, I will smoke with him and have a nice chat.
Personally, I think Vietnamese are very friendly, humble and good manner. I don't see any difference between Vietnamese and Chinese(we both speak English)
