for a long time, East Asian modern culture except Japanese anime is not popular in the world
a most important reason is that East Asian look (or mongoloid) is not popular in the world.
many non-Asian people even can't differentiate one Asian person with another, they think all Asian people look the same.
The west is dominant in the world and so is their look.
Indians, middle east people and south American people look more west than East Asian people.
so it will be more difficult for East Asian countries to export modern culture(movies, dramas, music) to non-Asian countries than other major countries, e.g, India, Turkey.
But the rise of Kpop and K-dramas have broken the limitations.
this is a good phenomenon.
And I think Kpop is laying a easy road to the outside world for future cultural export of China.
I see the rise of Chinese entertainment industry in recent years.
And I think 5 or 10 years later, Chinese entertainment may take place of Kpop.
Let Kpop do the hard entry work for China
