南京大虐殺・従軍慰安婦強制連行の嘘

This is a very sensitive and emotional issue for Chinese. Especially the number issue [the number of victims (see In the 1990s)] is very sensitive in China. And secondly, Chinese scholars are not fully up-to-date on Japanese research or Japanese sources. In a sense they are handicapped to appreciate the kind of research done in Japan.
On the Japanese side I still see people primarily use the Rape of Nanjing as a political tactic. So not everybody in Japan is treating the Rape of Nanjing as a scholarly subject. In turn that creates a vicious cycle making it very difficult for Chinese scholars to accept or appreciate different views or conclusions in Japan.
