Japan and China are blaming each other for anti-Japan protests that have been breaking out in cities across China, and both sides are demanding an apology.
Japan's Chief Cabinet Secretary Hiroyuki Hosoda says China should never have allowed the demonstrations and violence to take place.
He says it is "very regrettable" that no apology was offered during a meeting in Beijing Sunday between the Chinese and Japanese foreign ministers.
In Beijing Monday, China's vice foreign minister Wu Dawei said the two countries' diplomatic relations are at their lowest point in more than 30 years, and that Tokyo is to blame.
If anyone is to apologize, the Chinese diplomat told reporters, it should be Japan. China says it has nothing to apologize for, and that Japan created the current problem by approving a history textbook that minimized Japan's involvement in atrocities committed on Chinese soil more than six decades ago.
