I am a Korean high school student, Minseo Park. I often read articles and hear the news from BBC website, and I found the error in the headline of your article. I would like to inform you and request you to correct it.

The headline of the article is "Russia threatened to ram US ship in Sea of Japan. I supposed that you are already aware of that the sea was recommended to be called "East Sea", not "Sea of Japan, since you mentioned it in your article. BBC is one of the biggest and powerful press in the world and have a huge effect on lots of people. One word in your article may cause confusions to many people who read and watch your news. We all agree that the global press like yours have the duty to spread the right information to readers and audiences. 

It would be very appreciated if you could fix the headline of your article. The word "Sea of Japan" should be corrected to "East Sea".

I sincerely thank you for your time. If you have any questions, feel free to contact me by email. I'm looking forward to hear from you.
