China's State Archives Administration started releasing a series of videos exposing the suffering of sex slaves at the hands of the Japanese military more than 70 years ago on August 15.

During the WWII, an estimated 200,000 "comfort women" were forced into providing sexual services to the Japanese army.

In spite of the concern over the "Comfort Women" issue from the international community, Japanese Prime Minister Shinzo Abe's Friday statement to mark the 70th anniversary of the end of World War II made no direct reference to the "comfort women".

To refute Japanese right-wingers’ denial of war crimes involving “comfort women”, the State Archives Administration of China has produced the online feature video:“Comfort Women”:Selected Archives on Japanese Army Sex Slaves, releasing the archives kept by some Chinese archival agencies and research institutions.

The eight-part video series will be released on the administration's website, one per day until August 23, 2015.
