South China Sea: China’s ‘dark fleet’ now targeting Sea of Japan

However, I kindly request you to consider changing Sea of Japan to East Sea.

It is historically and politically sensitive as the ocean is not really belong to Japan.

We are aware of the place is between countries.

Hope you are safe and happy for all.

Thank you^^!
