BEIJING, Aug. 15 -- China's State Archives Administration (SAA) on Friday began releasing documents and videos showing Japan's aggression and defeat to China during the 1930s and 1940s.

The 24-part video series, entitled "The Great Victory", will be released on the SAA website. one episode per day, following the release of Japanese war criminals' written confessions on 44 consecutive days since July 3.

The move is to mark the 69th anniversary of victory in both the national war against Japanese aggression and WWII.

The documents and videos are also a warning "never follow the road of Japanese militarists" said Li Minghua, deputy head of the SAA.

"The Japanese government has long lacked deep and profound reflection on some historical problems," said Wang Xinsheng, professor with the History Department of Peking University.

China has published such important historical materials online to counteract the current situation in Sino-Japanese relations, he said.

The material was collected from the Central Archives, the Second Historical Archives of China, the China Film Archive and some local archives.

"These archives show that China's war against the Japanese was part of the world anti-fascist war, and China was the main oriental battlefield," said Guo Biqiang, director of research at the Second Historical Archives of China.

The war against Japanese aggression broke out in 1937 and ended on Aug. 15, 1945 with Japan's unconditional surrender, which also cemented total victory in WWII. More than 35 million Chinese people died or were wounded during the conflict.
