Chinese fishing boats have resumed their operations in the West Sea of Korea and the South Sea near Jeju Island, engaging in illegal fishing activities and causing harm to Korean fishermen. They are using large nets, which is prohibited in the Exclusive Economic Zone (EEZ), and playing a cat-and-mouse game with the Korean Coast Guard. This issue is also posing a problem for North Korea. In addition to Southeast Asia and South America, Chinese fishing boats are engaging in reckless fishing in these regions, requiring both individual country efforts and international cooperation to address the issue.
