High tension remains between both countries till this day as both countries are superpower and possess a great degree of national values. As a result, even a minor incident between both countries will lead to enormous tensions and controversies. Also, considering the fact that both hold ill thought about one another, which can even be seen by the comment of Japanese on China stating the communism nature hence conflict in value with the Japanese value considering that they adopt capitalism.
From the Japanese point of view, the Chinese tend to exaggerate thing hence leading to them thinking that the whole incident was a hoax and never occurred. Also, with Japanese have access to limited and wrong sources on the incident, the majority of the public do not have any idea of the genocide and even deny the fact so as to support their nation as they are taught from a young age that their nation is right and nation come before all. Hence, their action can be regarded as ignorance as they do not possess knowledge on the massacre or even taught about it differently.
For the Chinese, it is not wrong deem Japanese wrong and merciless at all as they have been through so much during the genocide. Also to be hurt by the Japanese action is no surprise as well as the have never been given a formal apology, which they still demand to this day. Although getting an apology will not heal their wound, their acceptance of the wrongdoing and genocide will give them a some healing.
