Korean claim; Defect on the Chart S-23?

The previous text  "Japan Sea（52）" on S-23

52 Japan Sea 
On the Southwest
The Northeastern limit of the Eastern China Sea (50) and the Western Limit of the Inland Sea (53）.

Kim-Shin claimed it is invalid of the S-23 Japan Sea text ,lack of limit definiation of southwestern limit of the Japan Sea（Japanese.yonhapnews　25ｔｈApr2012）　But it must not be a ground that the name of Sea of Japan is invalid and ground to add "East Sea". It is just a very easy solution of the text to fix a text below example. The boundary between Eastern China Sea and Sea of Japan is already defined. In addition, the definiation of the Yellow Sea(51) southeast boundary is already explained in S-23.

52 Japan Sea
On the Southwest
The Northeastern limit of the Eastern China Sea (50) and the Western Limit of the Inland Sea (53）and "Southeastern limit of Yellow Sea (51)

（日本人向けに簡単に説明：確かに52日本海の南西端の説明があいまいなことは確かである。一方、50東海（東シナ海）の北端と、53黄海の南東端は既に定義が出来ている。このことから50日本海の説明に、”53黄海の南東端”を付け加えればよいだけ）
