Japan-South Korea Agreement on The Continental Shelf Was Signed: January 30, 1974

January 30, 1974 is the day when the “Japan-Korea Continental Shelf Agreement” was signed in Seoul.

On this day, Japan and South Korea signed an agreement on the continental shelf of both countries.

In May 1972, South Korea set up its own mining area beyond the midline between Japan and South Korea.

This was the trigger for this agreement.

This can be divided into two types, commonly known as the “Northern Agreement” and the “Southern Agreement”.

The official names of each are “Agreement on the demarcation of the northern border between Japan and the Republic of Korea on the northern border of the continental shelf adjacent to both countries” and “Joint development of the southern part of the continental shelf adjacent to both countries between Japan and the Republic of Korea”.

The outline of each is as follows.

[Northern Agreement] The boundary between the continental shelves of both countries will be “from 33 degrees north latitude to 36 degrees north latitude”.
The boundary line passes through the West Channel of the Korea Strait, but is approximately halfway between the territorial waters baselines of both countries.

[Southern Agreement] Detailed provisions on joint development of oil and natural gas resources. It is valid for at least 50 years until 2028.

Both came into effect on June 22, 1978.

China is opposed to this agreement because it claims that Japan’s western waters of Kyushu are its exclusive economic zone.
