Twenty-One Demands
Japan seized concessions in areas of China towards the end of the Qing Dynasty. Dissatisfaction with the settlement and the Twenty-One Demands by the Imperial Japanese government led to a severe boycott of Japanese products in China in 1915. Bitterness in China persists over the Second Sino-Japanese War and Japan's post-war actions. This sentiment may also be at least to some extent influenced by issues related to Chinese people in Japan.
