Who do you think you are to give your opinions about China and its neighbours? Have you ever lived in Vietnam, Korea or Japan and see how Chinese culture becoming a trend here?
Even Japan now trying to come back to its roots, i.e. Chinese culture. In Vietnam, Chinese cultural elements is permeating to daily activites and more and more popular not by years, but by days. Before 1975, North Vietnam tried to get rid of Sino-Vietnamese and use "pure" Vietnamese words, but now media trying to use more and more Sino-Vietnamese. They even use Chinese grammar, i.e. putting adjective before nouns. New buildings imitate Chinese style. Music imitate Chinese. Old anniversaries, which originated from China and almost forgotten, now being revived.
People in the West is brainwashed that other East Asian hate China. In fact, it is very complicated. It is a love-hate relationship.
I love and respect China, but do not like the Sinification of Vietnamese culture. I like to keep our Vietnamese distinctive culture and do not want ours to be a version of Chinese.
The same in Korea and japan.
With regards to Hong Kong recent protests, I see the similarities with Southern Vietnamese. We North Vietnamese bring civilization to them, give them one of the best education in the world, teach them how to live more civilized. But many still hate us and call us conquerors (this hatred originated not since 1975, but perhaps hundred years before that). However, I believe with time, we will be more assimilated (says 50 - 100 years).
