The Japanese government has criticized former PM Hatoyama's acknowledgment of a "territorial dispute" with China. The day after his remarks, Hatoyama visited the Nanjing Memorial, which is for those killed in a massacre by Japanese forces. “In the eyes of the Chinese public, his visit is very valuable and undermines those in China who argue that all Japanese suffer from amnesia about wartime misdeeds," said Jeff Kingston, director of Asian studies at Temple University Japan.
