The current prime minister's blatant dissemination of false information targeting specific groups from certain countries—I believe everyone understands the consequences of such behavior. China has not banned its citizens from traveling to Japan; this is merely a safety warning, and certainly not an economic penalty. We all know that China has the capability to cripple the Japanese economy in many ways, and the tourism restrictions are primarily for security reasons.You are probably a novice in Geopolitics. This is not about safety warning at all. Cause everyone knows Japan is perfectly safe. This is all about punishing Japan by reducing Chinese tourism. This is an economic punishment move.
I suggest you look into the recent attacks against Chinese tourists in Japan. What's even more worrying is that most of these attacks have not been further investigated or investigated by the Japanese government, which is tantamount to condoning these attacks.
