China on Tuesday reaffirmed its support for joint efforts in nominating comfort women files to the Memory of the World Register.
"As far as we know, some NGOs from countries and regions where comfort women suffered are preparing to jointly nominate the files," Foreign Ministry spokesperson Hua Chunying told a routine press briefing.
"We are supportive of this," she added.
The Memory of the World Programme, established in 1992 by the UN Educational, Scientific and Cultural Organization (UNESCO), preserves the world's most important documents.
"The enslavement of women was a crime by Japanese militarists during World War II," Hua said, adding that inscribing the files in the UNESCO register will help people everywhere realize the cruelty of war, cherish peace and protect human dignity.
Historians estimate that about 200,000 comfort women from China, the Korean Peninsula and Southeast Asia were forced to serve in Japanese military brothels during WWII.
