Mao Zedong, the Chairman of the Chinese Communist Party and the founding father of the People's Republic of China, was reported to have expressed his gratitude to the Japanese military and political figures who visited China in the 1950s and 1970s.
Mao said that the Japanese invasion of China had awakened the Chinese people to solidarity.
In the 21st century, these remarks by Mao caused strong reactions on the Internet in China.
With the 2020 Hong Kong Diploma of Secondary Education Examination (HKDSE) history subject controversy on the historical understanding of Japan's invasion of China,[1][2] these remarks have returned to the spotlight on Hong Kong and mainland Chinese Internet.[3] Nevertheless, the word "thanks" expressed by Mao has been interpreted by many scholars as dark humour.[4][5]
