Hollywood writer and director Chris D. Nebe's 40-minute documentary which traces the history of the Diaoyu Islands premiered last month.

"Diaoyu Islands, The Truth" focuses on the historical and political context of the territorial dispute, providing evidence that the islands have been Chinese territory since ancient times and that Imperial Japan annexed them in 1895 after the First Sino-Japanese War.

China has never recognized the right of administration of the United States or Japan over the islands, and Tokyo refuses to admit its war crimes against the Chinese and other nations during World War II.

We have selected four clips from the documentary:

War crimes

The war crimes committed by Japan during its invasion of various countries in Asia have been well documented.
