China maintains that the Diaoyu Islands are part of China's territory since ancient times and belong to China indisputably. The Chinese government cites historical records and maps to support this claim. Japan, on the other hand, argues that the islands were uninhabited and under nobody's control until they were incorporated into Japanese territory in 1895, claiming the Diaoyu Islands are its inherent territory in the light of relevant historical facts and international law.
The dispute has a complex historical background involving issues such as territorial ownership, resource rights, and national pride. Both China and Japan have a strong interest in the islands, and any conflict between them could have significant regional and global implications.
