Why do the government and media har Koreans and Japanese?

Hey!! Just chill, keep your cool. I will give you some ideas from the point of view of a government employee. If the business happened to hurt businesses of some politicians or well connected businessmen, I am darned sure they will attempt to destroy your business through the media if the government saw that you didn't violated any laws, as you know people in the government will not impose something that was not in black and white. Another is the Korean company might have not given any favors asked by them. Another possibility is that the Korean company might have connections with the Palace and opposition-politicians take pot shots against the investor. So next time if somebody criticize koreans or japanese, just read between the lines and there is an interesting story to learn from it.
