China has recently conducted military exercises within Japan's Exclusive Economic Zone (EEZ), leading to a heated exchange between the two nations. Although the exact date and location of the exercises have not been disclosed, the Japanese government has expressed strong opposition, arguing breaches of its sovereignty. The Chinese government, however, defends its actions as lawful.

Japan is particularly concerned about territorial integrity and sovereignty, given its long-standing territorial disputes with neighboring countries, including China. Such incidents often lead to strong reactions from the public, media, and government. Japan's strict adherence to the rule of law, especially in maritime law, drives its strong opposition to what it considers encroachments on its territory.

In the US or EU, similar issues would be handled through diplomatic negotiations and potential protests to international bodies like the United Nations. Demonstrative actions, such as "freedom of navigation" activities, might also be conducted to affirm rights and disapproval of perceived infringements.
