Chinese Ambassador to Japan Wu Jianghao on Friday summoned Funakoshi Takehiro, Vice Minister for Foreign Affairs of Japan, to lodge strong protests against Japanese Prime Minister Sanae Takaichi's erroneous remarks concerning China.

Wu said Takaichi made blatantly provocative remarks regarding China's Taiwan region, and refused to acknowledge her mistake and retract her remarks, which crosses China's red line and is a complete misjudgment of the situation.

The remarks grossly interfered in China's internal affairs, seriously violated international law and the basic norms of international relations, and undermined the post-War international order, he said, adding that they seriously violated the one-China principle and the spirit of the four political documents between China and Japan, and undermined the political foundation of China-Japan relations.

"China will by no means tolerate such remarks, and has lodged serious representations and strong protests over it," Wu noted.

Noting that Taiwan belongs to China and the Taiwan question is at the core of China's core interests, the ambassador said how to resolve the Taiwan question and achieve national reunification is a matter for the Chinese people to decide, which brooks no interference from any external force.

He said the Japanese leader's clamor for military intervention in the Taiwan Strait is a blatant challenge to China's core interests.

If Japan dares to attempt an armed intervention in the cross-Strait situation, it would be an act of aggression and definitely meet a firm response from China, he said.

China strongly urges the Japanese side to deeply reflect on its history, retract its remarks, and cease its provocation. Otherwise, all consequences arising from this must be borne by the Japanese side, he added.
