Diplomatic tensions between China and Japan escalated following a breach of protocol by the Chinese Foreign Ministry. During a press conference on September 30, spokesperson Guo Jiakun referred to Japanese Prime Minister Sanae Takaichi by name only, omitting her official title.

Japan has formally requested that China show ‘appropriate respect’ to the Prime Minister. Japanese Foreign Ministry spokesperson Toshihiro Kitamura stated that Tokyo has relayed its concerns to Beijing, noting that international protocol dictates leaders be addressed with due respect regardless of political differences. 

The incident occurred while the Chinese spokesperson was discussing Japanese debates regarding the potential acquisition of nuclear weapons and nuclear-powered submarines. This dispute follows a period of strained relations, partly due to Takaichi’s previous comments suggesting that Tokyo might intervene in the event of an attack on Taiwan. While the protocol dispute has heightened frictions, Takaichi has signaled a desire for stability, characterizing China as an ‘important neighbor’ in recent policy addresses.
