In the opening ceremony, they moved their bodies, as did white singers. That was the best part of the singing. Later, I heard that it was the first time black and white singers had sung the piece together. If cultures mix, like international marriages, what is important is the individual. What you like, what you think and what you do for a living become very important.
Countries become trivial.
There will be no West and East. What counts are individuals. The Ozawa born in China, raised in Japan with Japanese citizenship, is not important anymore. What matters is myself as an individual. When the existence of individuals becomes important, regulations will become barriers.
