Japan Protests China's Unapproved Research Near Disputed Island
Japan and China are arguing about scientific research in the ocean.
Japan says China was doing research in its area without permission, near a small island called Okinotori.
Japan's coast guard told China to stop and complained.
China says it's allowed to do research there because the island is just rocks and shouldn't count as part of Japan's area.
Other countries, like Taiwan and South Korea, also disagree with Japan.
Japan accused China of conducting unapproved maritime research near Okinotori Island.
The incident occurred in Japan's exclusive economic zone (EEZ).
Japan's coastguard demanded the activity cease and lodged a diplomatic protest.
China claims the area is not subject to Japanese EEZ rights, as Okinotori is merely rocks.
Other nations, like Taiwan and South Korea, also dispute Japan's claim over Okinotori.
