On November 13, 2025, Vice Foreign Minister Sun Weidong summoned Japanese Ambassador to China Kenji Kanasugi to lodge stern representations with Japanese Prime Minister Sanae Takaichi’s wrong words and deeds related to China.

Sun Weidong said that Japanese Prime Minister Takaichi Sanae openly made provocative remarks related to Taiwan during his defense in Congress a few days ago, implying that he might intervene in the Taiwan Strait issue with force, and the nature and impact are extremely bad. After China's repeated solemn representations, Japan still refuses to repent and withdraw its wrong remarks. China is strongly dissatisfied and firmly opposed to this, and has made solemn representations and strong protest to Japan.

Sun Weidong pointed out that Gao Shi’s Taiwan-related remarks are extremely wrong and dangerous, grossly interfering in China’s internal affairs, seriously violating international law and basic norms of international relations, seriously undermining the post-war international order, seriously violating the one-China principle and the spirit of the four political documents between China and Japan, seriously undermining the political foundation of Sino-Japanese relations, and seriously hurting the feelings of the Chinese people. The 1.4 billion Chinese people will never agree to this!

Sun Weidong emphasized that the Taiwan issue is the core of China's core interests and is an untouchable red line and bottom line. Taiwan is China's sacred territory and Taiwan affairs are purely China's internal affairs. How to solve the Taiwan issue is the Chinese people's own business and does not tolerate any external interference. This year marks the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War, as well as the 80th anniversary of Taiwan’s liberation. 80 years ago, the heroic Chinese people defeated the Japanese invaders after 14 years of bloody fighting. Today, 80 years later, if anyone dares to interfere with China's reunification in any form, China will definitely give him a head-on blow! China once again urges Japan to deeply reflect on its historical crimes, immediately reflect on and correct its mistakes, withdraw its bad remarks, and not go further down the wrong path. Otherwise, Japan must bear all the consequences.
