"In the international community, survivors of South Korean 'comfort women' speak out their anger bravely. But voices of those from China are relatively weak," China News Service quoted the 56-year-old artist as saying on Tuesday.

"I hope to provide spiritual support to those Chinese women survivors through my paintings, and to help them voice their misfortunes."

In order to better understand the history, Poirot lived a month in the Nanjing Museum of the Site of Lijixiang Comfort Stations from September to October.

"During my stay here, I saw the pictures of these 'comfort women' every day. I felt deeply grieved when I saw their painful expressions…This (the museum) is a place where people would cry consciously. I almost finished these paintings in one go," Poirot said. He also said he hopes his brush works could help call for peace of humankind.
