A documentary film that focuses on China's resistance to the Japanese invasion during World War II is set to greet Chinese audiences, more than 70 years after it was made.

The Oscar winner, 'Kukan': The Battle Cry of China, was filmed by American correspondent Rey Scott in the 1930s.

Sponsored by Chinese American filmmaker Li Ling-Ai, Scott visited China four times since 1937, and he recorded the hardships faced by ordinary people in the war-torn China.

The research and collaborative innovation center of Chongqing has acquired the rights to screen the film in China.

The movie premiered in the United States in 1941 and was even watched by late U.S. President Franklin Roosevelt.
