I am well aware of the fact that this incident causes conflict between Japan and Korea.
And I understand that changing the name is not that simple a task.
However, it is correct to mark the name of the place you know 'Sea of Japan' as 'East Sea'.
I think one wrong word can undermine the credibility of the entire news.
Please check again and correct it.
If it is difficult to completely change it, why don't you mark the two together?
