China on Tuesday urged Japan to seriously reflect on the past aggression of Japanese militarism in reaction to Prime Minister Fumio Kishida's warning to Beijing against changing the status quo by force.

Kishida said Monday that the Group of Seven leaders will seek to send a strong message to the world during their summit later this week in Hiroshima that they will not accept "unilateral attempts by China and Russia to change the status quo by force," in the face of Beijing's military assertiveness in the Indo-Pacific.

Chinese Foreign Ministry spokesman Wang Wenbin pointed out at a press conference that some forces in Japan "have been doing all they can to whitewash the history of aggression" and asked, "Isn't this just an attempt to change the status quo?"

"If Japan truly opposes unilateral changes to the status quo, it should unequivocally check the regressive behavior of the abovementioned forces," Wang said.

He also criticized the view held by some Japanese that any contingency concerning Taiwan would be an emergency for Japan, urging Tokyo to abide by the one-China principle -- namely that both the mainland and Taiwan belong to one and the same China.

As the host of the G-7 summit from Friday, Japan is "obsessed with stoking and creating bloc confrontations, which undermines the interest of the region," Wang said, expressing China's firm opposition to it.
